Probiotic Chews For Dogs Supplement
Verified Jun 11, 2026
A soft chew probiotic supplement for dogs of all sizes, providing 1 billion CFU from a blend of nine clinically studied probiotic strains plus prebiotic FOS. It’s designed to support healthy gut bacteria, stool quality, and general digestive comfort, and uses chicken liver and brewer’s yeast to make the chews more palatable. This is meant to be added to a regular complete and balanced diet, not used as a primary food.
This is a well-designed probiotic supplement for dogs, with a diverse mix of lactobacillus, bifidobacterium, and streptococcus strains at a meaningful CFU level for daily support. The addition of prebiotic FOS helps feed the beneficial bacteria, which can make the probiotic blend more effective. It’s a good option for ongoing digestive support in otherwise healthy dogs, as long as you’re comfortable with the flavoring ingredients like chicken liver and brewer’s yeast.

At a Glance
KibbleLab Review
Strengths
- Provides 1 billion CFU per chew from nine named, clinically studied probiotic strains, which is a solid daily dose for most dogs.
- Includes prebiotic fructooligosaccharides (FOS) to help nourish and support the growth of beneficial gut bacteria.
- Uses liver and yeast as palatability enhancers, which many dogs find very tasty and can make daily dosing easier.
- Free from artificial flavors and dyes, relying instead on more functional inactive ingredients like flax oil, mixed tocopherols, and herbal extracts for stability and flavor.
Considerations
- Contains chicken liver, so it isn’t suitable for dogs with chicken allergies or strict chicken-free diets.
- Includes brewer’s yeast, which some dogs with yeast sensitivities or on low-yeast diets may need to avoid.
- This is a supplement only and does not provide complete and balanced nutrition, so it must be given alongside a regular dog food.

Top 5 Ingredients Explained
01
FOS
Fructooligosaccharides (FOS) are non-digestible, soluble prebiotic fibers commonly added to pet foods and supplements to feed beneficial gut bacteria and support intestinal health. In dogs and cats they can help improve digestion, stool quality and immune support, but excessive amounts may cause gas or loose stools in sensitive animals so levels should be balanced and introduced gradually.
02
Probiotic Blend
A probiotic blend is a mixture of live beneficial bacteria added to pet foods to support healthy digestion, maintain a balanced gut microbiome, and contribute to immune health in dogs and cats. Benefits can include improved stool quality and reduced occasional digestive upset, but effectiveness depends on the specific strains, dose and viability (CFU) and some pets may experience mild, transient GI changes; immunocompromised animals should receive veterinary guidance and probiotics are not a substitute for veterinary care.
03
Lactobacillus Acidophilus
Lactobacillus acidophilus is a probiotic live bacterial culture commonly added to pet foods and supplements to help maintain a healthy intestinal microbiota, support digestion, and reduce the risk or severity of diarrhea and antibiotic-associated gastrointestinal upset in dogs and cats. It is generally considered safe and can support immune and gut health, but efficacy is strain- and dose-dependent, is not a substitute for veterinary care, and owners should consult their veterinarian—especially for young, elderly, or immunocompromised animals—before use.
04
Lactobacillus Casei
Lactobacillus casei is a probiotic bacterial strain added to dog and cat foods and supplements to support digestive health by helping maintain a balanced gut microbiome, which can improve stool quality and nutrient absorption. Its benefits are strain- and dose-dependent and may include modest immune support, but viability is affected by processing and storage and pets with weakened immune systems or serious illness should consult a veterinarian before use, as transient GI upset or interactions with antibiotics can occur.
05
Lactobacillus Salivarius
Lactobacillus salivarius is a probiotic bacterial strain added to pet foods and supplements as a live-culture ingredient to help support healthy gut microbiota, digestion, and intestinal immune function in dogs and cats. It is not a nutrient but can improve stool quality and reduce digestive upset in some animals; products should list the specific strain and viable CFU, and use with caution in severely immunocompromised pets or under veterinary guidance when animals are on antibiotics.
