What Makes a Good Dog Probiotic
- CFU count — look for at least 1-5 billion CFU per serving for maintenance
- Multiple strains — different strains colonize different gut sections
- Survivability — strains must survive stomach acid; microencapsulation improves this
- Prebiotics included — prebiotic fiber feeds the probiotic bacteria and amplifies effect

FAQ
How long should I give my dog probiotics?
For acute issues (post-antibiotic, travel diarrhea): 2-4 weeks. For chronic digestive issues or immune support: ongoing daily use is appropriate and safe long-term.
Can I give my dog yogurt instead of a probiotic supplement?
Plain, unsweetened yogurt is safe for most dogs but CFU count is much lower than supplements and strains aren't optimized for canine gut microbiome. Supplements are significantly more effective for therapeutic use.
