Quick answer
Our top pick is Purina Pro Plan Veterinary Supplements FortiFlora, a probiotic powder backed by research and recommended by many veterinarians. It contains a patented strain shown to support digestive and immune health, which may help with stress-related GI upset. For dogs needing a chewable, Zesty Paws Probiotic Bites offer a tasty alternative with added prebiotics and a blend of strains.
What to consider for Dog Probiotic For Anxiety
Anxiety in dogs can manifest as digestive upset, such as diarrhea or loss of appetite. Probiotics help maintain a healthy gut microbiome, which communicates with the brain via the gut-brain axis. When choosing a probiotic for anxiety, look for products with strains like Bifidobacterium longum or Enterococcus faecium, which have been studied for stress-related benefits. Also consider the form (powder, chew, capsule) and your dog’s preference. Always consult your veterinarian before starting any supplement, especially if your dog is on medication or has a health condition.
What to look for in a health product (dental, probiotic, joint, allergy or calming supplement)
Look for an NASC quality seal, which indicates the product meets strict manufacturing standards. For probiotics, check the colony-forming units (CFU) count and that the strain is identified. Evidence-based ingredients at meaningful amounts are key: for probiotics, a minimum of 1 billion CFU per serving is common. Ensure the product is labeled for dogs and dosing instructions are clear by weight. Avoid products with vague proprietary blends. For other health products, similar principles apply: look for seals like VOHC for dental, and for joint supplements, glucosamine and chondroitin at effective doses.

What to avoid
- Avoid products claiming to cure or prevent anxiety or other diseases.
