Pet Food Ingredient
Probiotics
Live bacterial cultures added to pet food or fed as a supplement to support gut-microbiome diversity. Common strains in pet products: Enterococcus faecium SF68, Bifidobacterium animalis, Lactobacillus acidophilus.
Also labelled as
Regulatory status
AAFCO permits probiotic strains listed in the Association of American Feed Control Officials Official Publication. Manufacturers must specify strain and guaranteed CFU at end of shelf life.
Key notes
- —Heat-sensitive — strains added before extrusion are often largely killed by the time the kibble reaches the pet. Post-extrusion spray-on or capsule supplementation is more reliable.
- —Effective doses are strain-specific. Most generic "multi-probiotic" products lack the specific strain + CFU count that controlled trials used; a named-strain product with guaranteed potency through the expiry date is a better bet than a generic blend.

Common questions
Do probiotics in dog food actually work?
Depends on the strain and the form. Probiotic strains are heat-sensitive — strains added before extrusion are often largely killed by manufacturing heat. Post-extrusion spray-on or separate capsule supplementation is more reliable than in-kibble inclusion. Named strains with guaranteed CFU counts through expiry (e.g. Enterococcus faecium SF68) are more credible than generic "probiotic blend" claims.
Are probiotics safe for dogs long-term?
Yes — no documented safety concerns at typical supplemental doses. AAFCO permits specific probiotic strains listed in its Official Publication. Long-term supplementation typically doesn't cause issues; at worst, ineffective products waste money without causing harm. Dogs with severely compromised immune systems (chemotherapy, organ transplant) should consult a vet first.
