Musculoskeletal Strength & Mobility in Dogs

​Musculoskeletal strength and mobility form the foundation of how dogs move, play, work, exercise, and interact with their environment. Every step, jump, climb, turn, or change in posture depends on the coordinated function of bones, joints, muscles, tendons, ligaments, and the nervous system. Together, these structures create a dynamic system that supports body weight, protects internal organs, enables movement, and adapts to changing physical demands.

Healthy mobility is far more than the ability to walk without limping. It reflects the body's capacity to generate force, maintain balance, distribute weight efficiently, absorb impact, and perform everyday activities comfortably. Whether a dog is an energetic puppy, an athletic working dog, or a senior companion, musculoskeletal health influences physical function throughout every stage of life.

​

Research over the past several decades has significantly improved understanding of canine movement. Modern veterinary medicine increasingly uses objective tools—including gait analysis, force-platform technology, wearable motion sensors, range-of-motion measurements, and validated owner questionnaires—to evaluate mobility more accurately than subjective observation alone (Clark & Comerford, 2023; Clark et al., 2023). These advances are helping researchers identify subtle changes earlier while improving consistency in musculoskeletal assessment.

​

Although methods for measuring mobility continue to advance, important knowledge gaps remain. Compared with human medicine, standardized methods for directly measuring muscle strength in dogs are still limited, and many current assessments rely on functional performance rather than true strength testing (Frye et al., 2022; Wells et al., 2024). This evolving evidence illustrates both the progress made in canine biomechanics and the opportunities for future research.

This Major Pillar introduces the core principles of musculoskeletal strength and mobility in dogs and provides an evidence-based overview of the systems that influence movement throughout life.

​

What This Major Pillar Covers

 

The canine musculoskeletal system is an integrated network that allows movement while maintaining structural stability. Bones provide the framework of the body, joints permit controlled motion, muscles generate force, and connective tissues transfer that force to create coordinated movement. None of these components function independently. Instead, mobility depends on continuous interaction among skeletal structures, soft tissues, neurological control, and mechanical forces generated during everyday activity.

 

This educational hub introduces three interconnected areas of canine musculoskeletal health:

• Mobility & Joint Health in Dogs, which explores how joints function, how movement changes throughout life, and how mobility is evaluated in veterinary medicine.

• Bone Health in Dogs, which explains skeletal structure, bone remodeling, mechanical loading, and the role of healthy bones in lifelong mobility.

• Muscle Function in Dogs, which examines muscle anatomy, force generation, muscle adaptation, and how muscles support posture, balance, and locomotion.

 

Together, these topics create a comprehensive overview of canine movement without focusing on specific diseases or treatments. Instead, the emphasis is on understanding normal function, the factors that influence mobility, and the growing body of scientific evidence for studying canine musculoskeletal performance.

​

Modern veterinary research combines clinical observation with biomechanics, imaging, computer modeling, wearable technology, and functional assessment tools to better understand how dogs move under both normal and altered conditions  (Brown et al., 2020; Stark et al., 2021). These multidisciplinary approaches continue to improve knowledge of movement while supporting more objective methods for evaluating musculoskeletal function.

​

Why This Area Matters

 

Movement is central to canine health and welfare. The ability to walk, run, climb stairs, rise from rest, maintain balance, and perform normal daily activities depends on efficient interaction among muscles, bones, joints, and connective tissues. Even subtle changes in movement may reflect alterations within this complex system.

​

Musculoskeletal conditions are among the most common reasons dogs experience reduced physical function. Research consistently identifies osteoarthritis, aging, obesity, orthopedic disease, neurological disorders, and recovery following injury or surgery as important influences on mobility (Clark & Comerford, 2023; Wells et al., 2024). These factors often affect more than locomotion alone. Reduced mobility can also influence participation in daily activities, physical fitness, social interaction, and overall quality of life.

​

One challenge identified throughout the scientific literature is that mobility changes often develop gradually. Owners may notice obvious limping, but early changes in gait, posture, weight distribution, or activity levels can be much more difficult to detect without a structured assessment. Objective gait analysis has demonstrated that measurable biomechanical differences often precede more apparent clinical changes (Clark et al., 2023).

​

Researchers increasingly recognize that evaluating mobility requires more than observing whether a dog walks normally. Comprehensive assessments incorporate multiple dimensions of function, including:

​

• gait characteristics

• stance and posture

• joint range of motion

• weight distribution

• balance

• muscle condition

• owner-reported functional ability

• performance during standardized movement tasks

 

Rather than relying on a single measurement, combining these approaches provides a more complete understanding of musculoskeletal health (Montalbano, 2022; Clark & Comerford, 2023).

​

Scientific interest in canine mobility also extends beyond clinical medicine. Working dogs, sporting dogs, assistance dogs, military dogs, and search-and-rescue dogs perform physically demanding tasks that place unique mechanical loads on the musculoskeletal system. Studies examining locomotion, muscle activation, joint loading, and movement efficiency contribute to a broader understanding of canine biomechanics and inform future research on performance, injury prevention, and rehabilitation (Charles et al., 2025; Cain et al., 2025).

​

How This Major Pillar Relates to Canine Health Overview

 

Musculoskeletal strength and mobility are closely connected with nearly every aspect of canine health. While this pillar focuses specifically on bones, joints, muscles, and movement, these systems interact continuously with other body systems described throughout the Canine Health Overview.

​

Movement depends on healthy neurological control to coordinate muscle contraction, maintain balance, and regulate posture. Cardiovascular and respiratory systems supply oxygen and nutrients that support muscle activity during exercise and recovery. The endocrine system influences bone remodeling, muscle metabolism, and body composition. Nutrition provides the building blocks required for skeletal growth, muscle maintenance, and connective tissue health. Body weight also affects mechanical loading across joints and bones, illustrating the close relationship between musculoskeletal function and metabolic health.

Research demonstrates that factors such as aging, obesity, workload, breed, and body conformation influence how these systems interact over time. For example, obesity alters weight distribution during locomotion, while improvements in body condition are associated with more balanced loading patterns and better physical fitness outcomes (Welter et al., 2026). Likewise, aging contributes to measurable reductions in joint mobility, even among otherwise healthy dogs, emphasizing that movement reflects both structural and physiological change across the lifespan (Lorke et al., 2017).

​

Advances in veterinary biomechanics further demonstrate that movement cannot be understood by examining individual structures in isolation. Three-dimensional musculoskeletal computer models estimate muscle forces, joint loading, and limb mechanics during locomotion, providing insights that complement traditional clinical evaluation (Brown et al., 2020; Stark et al., 2021). These models continue to improve understanding of how different body systems work together to produce efficient movement.

​

Because mobility reflects the integrated function of multiple physiological systems, it serves as an important indicator of overall canine health rather than simply orthopedic status.

Key Concepts Within This Pillar

 

Understanding musculoskeletal strength and mobility begins with several foundational concepts that appear consistently throughout the scientific literature.

​

Mobility

 

Mobility refers to the ability to move safely, efficiently, and independently during everyday activities. Modern veterinary frameworks recognize mobility as more than walking ability alone. It includes transitions such as rising, sitting, turning, climbing, balancing, and maintaining comfortable movement across different environments (Wells et al., 2024).

​

Gait

 

Gait describes the coordinated pattern of limb movement during locomotion. Veterinary gait analysis evaluates timing, stride characteristics, force production, symmetry, and weight distribution to identify normal and altered movement patterns. Objective gait assessment has become one of the strongest evidence-based tools for measuring canine mobility (Clark & Comerford, 2023; Altermatt et al., 2023).

​

Joint Function

 

Healthy joints provide controlled motion while maintaining stability. Their function depends on the coordinated interaction of cartilage, synovial structures, ligaments, tendons, surrounding muscles, and bone. Joint range of motion represents one measurable aspect of mobility, although functional movement depends on many additional biomechanical factors.

​

Bone Health

 

Bones provide structural support, protect vital organs, store minerals, and serve as attachment sites for muscles. Bone is continuously remodeled throughout life in response to biological processes and mechanical loading, allowing the skeleton to adapt to changing physical demands.

​

Muscle Function

 

Skeletal muscles generate the forces required for posture, locomotion, balance, and movement. Muscle architecture, fiber composition, and neuromuscular coordination influence how efficiently dogs perform different physical activities. Breed-specific differences in muscle structure contribute to variation in athletic specialization and movement patterns (Webster et al., 2014; Van Boom et al., 2023).

​

Functional Assessment

 

Rather than relying on a single measurement, contemporary veterinary medicine evaluates musculoskeletal function using multiple complementary approaches. These include gait analysis, range-of-motion measurements, force-platform testing, wearable sensors, functional scoring systems, and validated owner questionnaires. Together, these methods provide a more comprehensive picture of canine mobility than subjective observation alone (Montalbano, 2022; Clark et al., 2023).

​

The following sections explore the three major components of this pillar—mobility and joint health, bone health, and muscle function—to illustrate how each contributes to lifelong movement and overall musculoskeletal health in dogs.

​

Mobility & Joint Health in Dogs

 

Mobility is one of the most visible indicators of canine musculoskeletal health. Every step, turn, jump, or change in posture requires coordinated interaction among joints, muscles, bones, tendons, ligaments, and the nervous system. When these structures function efficiently, movement appears smooth, balanced, and adaptable to different activities and environments. Even subtle changes in this coordination may influence how comfortably and effectively a dog moves.

​

Veterinary medicine increasingly views mobility as more than the absence of lameness. Contemporary frameworks define mobility as the ability to perform everyday activities—including walking, trotting, rising from rest, climbing stairs, turning, balancing, and changing direction—while maintaining comfort, stability, and functional independence (Wells et al., 2024). This broader perspective reflects the understanding that movement is closely linked to overall health, physical function, and quality of life.

​

Healthy joints play a central role in this process. Synovial joints provide controlled movement while distributing mechanical forces generated during locomotion. Cartilage, joint capsules, ligaments, surrounding muscles, and tendons work together to maintain both mobility and stability. Rather than functioning as isolated structures, joints are integrated into a larger biomechanical system that continuously adapts to changes in speed, terrain, body weight, and physical activity.

​

Research consistently identifies gait analysis as one of the most objective methods for evaluating canine mobility. Traditional clinical observation remains valuable, but visual assessment alone may overlook subtle changes in stride length, limb loading, or movement symmetry. Modern gait analysis combines technologies such as force platforms, pressure-sensitive walkways, inertial measurement units (IMUs), wearable accelerometers, and marker-based or markerless motion capture systems to quantify movement with much greater precision (Altermatt et al., 2023; Lee & Song, 2025; Palez et al., 2025).

​

These objective measurements are becoming increasingly important because mobility impairments often develop gradually. Scientific studies demonstrate that dogs with musculoskeletal disease frequently show measurable differences in movement before obvious gait abnormalities become apparent. In a validation study of the GenPup-M owner-reported assessment, mobility-impaired dogs exhibited lower peak vertical force, slower movement, and questionnaire scores that correlated well with clinical examination findings and force-platform measurements (Clark et al., 2023). Such findings support the growing use of standardized clinical metrology instruments alongside objective biomechanical data.

​

Contemporary mobility assessment is therefore multidimensional rather than dependent on a single test. Veterinary professionals increasingly combine information from several sources, including:

​

• gait analysis and stride characteristics

• posture and stance evaluation

• joint range-of-motion measurements

• weight distribution and limb loading

• muscle condition and symmetry

• neurological examination

• functional movement tasks

• owner-reported observations of everyday activity

 

This multimodal approach provides a more comprehensive picture of musculoskeletal function than any individual measurement alone (Montalbano, 2022; Clark & Comerford, 2023).

​

Age represents one of the most consistent influences on mobility. Research in healthy Beagles found measurable reductions in forelimb range of motion, particularly at the carpal joint, among older dogs compared with younger adults, demonstrating that normal aging can alter movement even in the absence of overt orthopedic disease (Lorke et al., 2017). These findings reinforce the importance of interpreting mobility within the context of life stage rather than assuming that all changes reflect disease.

​

Body condition also influences how dogs move. Excess body weight changes mechanical loading across joints and alters force distribution during locomotion. Emerging research indicates that improvements in body condition are associated with more balanced limb loading and improved cardiorespiratory resilience, illustrating the close relationship between musculoskeletal function and overall physical fitness (Welter et al., 2026).

​

Activity level and occupational demands further shape joint function. Dogs participating in athletic or working activities experience movement patterns that differ substantially from routine walking or trotting. Biomechanical investigations demonstrate that tasks such as jumping and negotiating A-frame obstacles require substantially greater joint motion and higher landing forces than level-ground locomotion, emphasizing how different activities place unique demands on the musculoskeletal system (Blake & Godoy, 2021). Likewise, studies of working dogs show that loaded trotting and specialized occupational tasks alter muscle activation and limb mechanics in ways that reflect adaptation to performance demands (Charles et al., 2025; Charles et al., 2025).

​

Mobility can also change following orthopedic surgery or injury. Research evaluating dogs after femoral head and neck osteotomy found that although many gait measures approached normal during trotting, compensatory movement patterns—including reduced hip extension and persistent muscle atrophy—remained detectable, highlighting the complexity of functional recovery (Engstig et al., 2022). Such studies demonstrate why comprehensive mobility assessment extends beyond observing whether a dog can simply walk.

​

Despite remarkable advances in measuring movement, important research gaps remain. One of the most significant is the absence of standardized methods for directly measuring muscle strength in dogs. Unlike human medicine, where grip dynamometry and manual resistance testing are widely established, veterinary medicine currently relies largely on functional performance measures as indirect indicators of strength (Frye et al., 2022). Similarly, recent reviews conclude that standardized assessments linking objective mobility measurements to everyday functional activities remain an active area of research (Wells et al., 2024).

​

Overall, the evidence indicates that canine mobility can now be evaluated with increasing accuracy through objective gait analysis, functional assessment, and validated clinical measurement tools. Continued advances in biomechanics, wearable technology, and standardized outcome measures are expected to further improve understanding of how dogs move throughout life.

​

Bone Health in Dogs

 

Bones form the structural framework of the canine musculoskeletal system. They provide mechanical support, protect vital organs, create attachment sites for muscles and tendons, store essential minerals, and serve as dynamic tissues that continually respond to mechanical loading throughout life. Every movement—whether standing, walking, running, or jumping—depends on the skeleton's ability to withstand and distribute forces while maintaining stability and flexibility.

​

Contrary to the common perception that bone is a static structure, the canine skeleton is highly active. Bone tissue undergoes continuous remodeling, a normal biological process in which older bone is resorbed and replaced with new bone. This process allows the skeleton to adapt to growth, aging, changing body weight, and varying levels of physical activity. Mechanical loading generated during everyday movement provides one of the key stimuli influencing bone architecture and strength, illustrating the close relationship between mobility and skeletal health.

​

Healthy bones also function as integral components of joints. Articular surfaces transmit forces between adjacent bones, while the underlying subchondral bone helps absorb and distribute mechanical loads generated during locomotion. Recent investigations of the canine talus demonstrate that subchondral bone density and strength vary across different regions of the joint surface; using computed tomographic osteoabsorptiometry (CT-OAM), researchers found these density variations directly map the joint's localized mechanical load history and weight-bearing patterns (Vali et al., 2025). These findings reinforce the concept that skeletal tissues continuously adapt to the physical demands placed upon them.

​

Bone health cannot be considered independently of the surrounding musculoskeletal system. Muscles generate the forces that move bones through joints, while tendons transmit muscular force and ligaments contribute to joint stability. Research examining tendon and ligament microstructure further demonstrates that connective tissues possess specialized mechanical properties that support efficient movement and help maintain structural integrity under repeated loading (Lau et al., 2024). Together, bones, joints, muscles, and connective tissues function as an integrated biomechanical system rather than as separate anatomical structures.

​

Veterinary researchers increasingly rely on advanced imaging and computational modeling to study skeletal biomechanics. Three-dimensional musculoskeletal computer models estimate joint loading, muscle forces, and skeletal movement during locomotion, providing information that is difficult to obtain through direct measurement in living animals. Studies have shown that subject-specific and whole-body models can reproduce experimental gait with reasonable accuracy while offering valuable insights into internal mechanical forces generated during movement (Brown et al., 2020; Stark et al., 2021).

​

Although these models continue to improve, researchers also recognize important limitations. Breed-specific skeletal anatomy, passive soft-tissue restraints, joint-stabilization mechanisms, and individual variation remain challenging to fully incorporate into biomechanical simulations (Brown et al., 2020; Dries et al., 2016). Ongoing refinements are expected to produce increasingly realistic representations of canine movement and skeletal loading.

​

Breed differences provide another important perspective on bone health and mobility. Dogs have been selectively bred for a remarkable range of body sizes, limb proportions, and functional roles, resulting in substantial anatomical diversity across breeds. These conformational differences influence posture, gait, joint mechanics, and weight distribution. Studies comparing breeds demonstrate measurable variations in standing posture, locomotion, and movement efficiency that reflect underlying skeletal structure rather than simply differences in training or activity level (Humphries et al., 2020; Humphries et al., 2020).

​

Research involving working dogs further illustrates how skeletal adaptation reflects occupational demands. Repetitive loading associated with sprinting, endurance work, detection tasks, herding, or assistance work places distinct biomechanical stresses on bones and joints. These demands interact with muscle architecture, connective tissues, and movement strategies to support specialized performance while also influencing long-term musculoskeletal adaptation (Charles et al., 2025; Charles et al., 2025).

​

Life stage also affects skeletal function. During growth, bones lengthen and remodel rapidly to accommodate increasing body size and changing mechanical demands. In adulthood, remodeling continues to maintain structural integrity, while aging is associated with gradual changes in bone quality, joint mechanics, and overall mobility. Rather than occurring in isolation, these age-related changes interact with muscle condition, body composition, and physical activity to influence lifelong musculoskeletal performance.

​

Bone loading also changes in response to alterations in movement. Studies evaluating dogs following orthopedic procedures have demonstrated persistent changes in limb loading patterns, even when overall gait appears clinically improved. Following femoral head and neck osteotomy, for example, compensatory changes in pelvic position, hip extension, and muscle mass remained evident despite relatively normal trot characteristics, highlighting the complexity of skeletal adaptation during recovery (Engstig et al., 2022).

​

Environmental factors further influence skeletal biomechanics. Experimental research examining dogs walking on slippery flooring demonstrates that altered surface conditions change musculoskeletal loading patterns and gait mechanics, suggesting that the external environment plays an important role in how forces are transmitted through bones and joints during everyday movement (Li et al., 2025; Chugo et al., 2026). These findings highlight the interaction between the skeleton and the environments in which dogs live and move.

Recent advances in digital technologies are expanding opportunities to study bone-related biomechanics outside traditional laboratory settings. Wearable inertial measurement units, pressure-sensitive walkways, motion-capture systems, and accelerometers enable researchers to evaluate skeletal movement and weight distribution under more natural conditions while improving the objectivity of mobility assessment (Altermatt et al., 2023; Reinstein et al., 2025). These technologies complement imaging and computational modeling by providing detailed information about how skeletal structures function during real-world locomotion.

​

Current research increasingly emphasizes that bone health should not be viewed simply as the absence of fractures or orthopedic disease. Instead, it represents the skeletal system's ability to support efficient movement, adapt to changing mechanical demands, and work in coordination with muscles, joints, connective tissues, and the nervous system throughout life. Continued advances in biomechanics, imaging, computational modeling, and objective movement analysis are helping researchers better understand these complex interactions while identifying new opportunities to study normal skeletal function.

​

Muscle Function in Dogs

 

Muscles are the engines of the canine musculoskeletal system. While bones provide structure and joints permit movement, skeletal muscles generate the force required for posture, balance, locomotion, and physical activity. Every voluntary movement—from standing and walking to running, jumping, and changing direction—depends on precisely coordinated muscle contractions working together with tendons, ligaments, bones, and the nervous system.

 

Muscle function extends well beyond producing movement alone. Healthy muscles stabilize joints, absorb mechanical forces during impact, support efficient weight distribution, and help maintain overall physical performance. Because muscles continuously respond to activity, workload, age, and body condition, they are highly adaptable tissues that reflect both the immediate demands placed upon them and long-term physiological changes.

 

Veterinary researchers increasingly recognize muscle function as a key component of lifelong mobility. However, compared with gait analysis and joint assessment, directly measuring muscle strength in dogs remains challenging. Reviews of the current evidence indicate that validated strength-specific tests remain limited, and many clinical assessments rely on functional performance rather than direct measurements of muscular force (Frye et al., 2022; Dahl et al., 2023). This represents one of the most important knowledge gaps in contemporary canine musculoskeletal research.

 

Instead of using hand-held dynamometers or standardized resistance testing commonly applied in human medicine, veterinary researchers frequently evaluate muscle function through indirect biomechanical measures. These include kinematic assessments that capture the geometry of movement (such as range of motion and joint angles) and kinetic metrics that quantify the forces causing that movement (such as ground reaction forces, posture, balance, and electromyography). Although these approaches provide valuable information about movement, they measure overall functional performance rather than isolated muscle strength (Frye et al., 2022; Montalbano, 2022).

 

Electromyography (EMG) has become one of the most informative methods for studying muscle activation during movement. Surface EMG allows researchers to evaluate when specific muscles contract during different phases of gait and how muscle activity changes under varying mechanical demands. For example, studies examining the gluteus medius, cranial biceps femoris, vastus lateralis, and longissimus muscles demonstrate that activation patterns vary according to gait phase, terrain, and direction of movement, reflecting the highly coordinated nature of canine locomotion (Yoshikawa et al., 2020; Miró et al., 2020).

 

Recent investigations also show that muscle recruitment varies with the physical demands placed on the body. Walking on inclines or declines alters forelimb muscle activation compared with level walking, illustrating how dogs continuously adjust muscular effort to maintain stability and efficient movement across different environments (Cain et al., 2025). Similarly, biomechanical studies of jumping and agility obstacles demonstrate that higher-impact activities require greater joint motion and increased muscular control than routine walking or trotting (Blake & Godoy, 2021; Clarke et al., 2024).

 

Muscle architecture varies considerably among dog breeds, reflecting generations of selective breeding for different functional roles. Sprinting breeds, endurance-working dogs, companion breeds, and livestock guardians each possess distinct musculoskeletal adaptations that influence movement efficiency and physical performance.

Comparative anatomical research has shown that Greyhounds bred for sprinting possess epaxial musculature adapted for rapid force production, whereas Staffordshire Bull Terriers exhibit muscle characteristics associated with greater trunk stability (Webster et al., 2014). 

 

Likewise, analyses of multiple working and companion breeds demonstrate significant differences in muscle fiber size and composition. Working breeds generally possess larger muscle fibers and greater proportions of fatigue-resistant Type I and Type IIa fibers—with Type IIa serving as an intermediate, oxidative-glycolytic bridge that balances rapid power generation with metabolic efficiency—adaptations consistent with sustained physical activity and endurance  (Osiak-Wicha et al., 2024; Van Boom et al., 2023).

 

These breed-specific adaptations highlight an important concept: muscle function is influenced not only by activity level but also by inherited anatomical characteristics. Consequently, normal movement patterns may differ among breeds without indicating abnormal musculoskeletal function.

 

Age also influences muscle performance throughout life. Healthy aging is associated with gradual changes in mobility, coordination, and joint range of motion, all of which interact with muscle function. Because muscles contribute substantially to joint stability and balance, age-related reductions in muscle mass or neuromuscular coordination may affect overall mobility even in the absence of a specific orthopedic disease (Lorke et al., 2017; Frye et al., 2022).

 

Muscle function is also closely linked to body condition and physical fitness. Changes in body composition influence how muscles generate force and how weight is distributed across the limbs during locomotion. Emerging research in obese dogs demonstrates that improvements in physical fitness are accompanied by changes in mobility and cardiorespiratory resilience, reinforcing the close relationship between muscular performance and whole-body health (Welter et al., 2026).

 

Modern technology is expanding opportunities to study muscle function in greater detail. Wearable inertial sensors, accelerometers, motion-capture systems, and computer-generated musculoskeletal models enable researchers to estimate muscle activation and internal force production during movement without invasive procedures. Whole-body computational models have reproduced experimental gait with encouraging accuracy, providing new insights into muscle coordination and locomotor biomechanics while highlighting the need for continued refinement of breed-specific anatomical data (Brown et al., 2020; Stark et al., 2021).

​

Despite these advances, researchers consistently identify the lack of standardized, validated strength testing as a major limitation in canine musculoskeletal science. Recent reviews emphasize that the field now has increasingly sophisticated methods for evaluating gait and mobility, yet still lacks universally accepted approaches to directly quantify muscular strength in everyday clinical practice (Frye et al., 2022; Wells et al., 2024).

​

Future research is expected to integrate wearable technologies, biomechanical modeling, functional performance testing, and objective muscle measurements into standardized assessment frameworks. As these tools continue to evolve, they will provide a more comprehensive understanding of how muscles contribute to healthy movement across different breeds, life stages, and activity levels.

Together with healthy bones and well-functioning joints, effective muscle function enables dogs to maintain balance, generate movement, respond to changing physical demands, and support lifelong musculoskeletal health.

Current Research Themes

 

Research on canine musculoskeletal health continues to improve how movement is measured and understood. Rather than relying solely on visual observation, researchers increasingly use objective tools that provide more consistent and repeatable data.

​

Objective Mobility Assessment

 

Wearable sensors, pressure-sensitive walkways, force platforms, and motion-capture technologies are making gait analysis more accurate and accessible. These tools help researchers measure stride characteristics, limb loading, and movement symmetry with greater precision than traditional observation alone (Altermatt et al., 2023; Lee & Song, 2025).

​

Functional Mobility

 

Researchers are also expanding mobility assessment beyond walking. New frameworks consider how dogs perform everyday activities, combining physical examination with functional tests and owner-reported observations to provide a broader picture of mobility (Clark & Comerford, 2023; Wells et al., 2024).

​

Musculoskeletal Biomechanics

 

Computer models are helping scientists estimate joint loading, muscle forces, and movement mechanics that cannot be measured directly in living dogs. These models continue to improve as more breed-specific anatomical data become available (Brown et al., 2020; Stark et al., 2021).

​

Measuring Muscle Strength

 

One of the largest research gaps remains the direct measurement of muscle strength. Although mobility can be assessed with increasing accuracy, reliable and standardized strength tests for dogs are still under development (Frye et al., 2022; Dahl et al., 2023).

​

Future Directions

 

Artificial intelligence, wearable devices, and digital monitoring systems are expected to improve long-term mobility tracking and provide more objective methods for studying musculoskeletal function in both research and clinical settings (Palez et al., 2025; Reinstein et al., 2025).

​
