In her article for Honest Paws, Dr. Gaffud examines the potential side effects when dogs are given probiotics, and she offers guidance for pet owners to introduce them safely.
Key points:
Digestive Upset: Mild gastrointestinal symptoms (diarrhea, vomiting, gas, bloating) are the most common when a probiotic is introduced. These are usually temporary and can be mitigated by starting with a low dose.
Allergic Reactions: Though rare, dogs may show hypersensitivity (itching, hives, swelling), so one must monitor carefully when starting a new strain or formula.
Increased Thirst: A transient rise in water consumption may occur as the gut microbiome adjusts.
Changes in Appetite: Appetite may go up or down temporarily as gut flora shifts.
Immune Stimulation / Overreaction: Dogs with sensitive immune systems might show signs of low-grade inflammation or allergic flare-ups.
Overgrowth or Dysbiosis: In some cases, introducing new microbes can disturb gut balance and allow opportunistic bacteria to overgrow.
Medication Interactions: Probiotics can theoretically interfere with absorption or efficacy of some drugs (especially those affected by gut flora or GI pH).
Dr. Gaffud notes that side effects are usually mild and transient, typically resolving within days to a few weeks as the dog’s system adapts.
She recommends always introducing probiotics gradually, monitoring the pet closely, consulting a veterinarian if problems persist, and avoiding overdosing or mismatch of strains.
This article underscores that probiotics can offer digestive and immune benefits, but prudent administration and veterinary oversight are key to minimizing risks.
