Buying Guide

Check probiotic strain diversity

Look for products listing multiple clinically studied strains (e.g., Lactobacillus, Bifidobacterium) because different strains target different digestive and immune functions

Consider CFU count and stability

Review colony-forming unit (CFU) counts and whether the formula guarantees CFUs through expiration or at time of manufacture, as stability affects effectiveness

Match format to your dog

Choose powders, soft chews, or tablets based on your dog’s size and feeding habits—for example, scoopable powders for mixing versus pumpkin-flavored soft chews for picky eaters

Look for added prebiotics and enzymes

Prebiotics (fiber sources) and digestive enzymes can enhance probiotic performance; products like those with PB6-style blends or enzyme support suit dogs with digestion or enzyme insufficiency

Account for allergy and ingredient needs

Check labels for common allergens or protein sources (e.g., duck in some formulations) and choose hypoallergenic or limited-ingredient options if your dog has sensitivities
