Strong Choice
Overall, this is a thoughtfully designed digestive and immune-support supplement that combines several probiotic strains, prebiotics, and enzymes in a palatable whey-based powder. It’s best suited for dogs who might benefit from extra gut support, such as those with occasional digestive upset, dogs on or recovering from antibiotics, or dogs under stress. As with any supplement, it should be used in addition to, not instead of, a complete and balanced diet.

Strengths
- Contains multiple probiotic strains (including Lactobacillus, Bifidobacterium, and Enterococcus) plus prebiotics like fructooligosaccharides and mannanoligosaccharides to help support a healthy gut microbiome.
- Includes a blend of digestive enzymes, which can aid in breaking down food components and may help some dogs with digestion and stool quality.
- Uses pumpkin seed, yucca, and herbal ingredients like licorice and anise that can offer additional digestive support and help with stool odor in some dogs.
- Powder form with very small serving sizes makes it easy to mix into food and adjust the dose for different body weights.
Considerations
- Contains dairy-derived ingredients (milk protein and sweet whey), so it may not be ideal for dogs with known dairy sensitivities or allergies.
- As a supplement, this does not provide complete and balanced nutrition and must be fed alongside a full, balanced dog food.
- The use of multiple herbal and yeast ingredients means that very sensitive dogs may occasionally react; it’s wise to introduce it gradually and monitor for any changes in digestion or skin.
- If your dog has a significant medical condition or is pregnant or used for breeding, this should only be used under direct veterinary guidance.

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
Active Yeast
Active yeast is used in pet food as a live yeast/probiotic and palatability enhancer, supplying protein, B‑vitamins, beta‑glucans and mannan oligosaccharides that can support digestion, healthy gut microbes and immune function in dogs and cats. While generally safe, it can trigger reactions in animals with yeast sensitivities and should be used with caution or under veterinary guidance for immunocompromised pets or animals with conditions affected by purine intake or urinary stone history.
03
MOS
MOS (mannan-oligosaccharides) are prebiotic fibers derived from yeast cell walls commonly added to dog and cat foods to support digestive health by encouraging beneficial gut bacteria and helping reduce adhesion of certain pathogens to the intestinal lining. They may improve stool quality and support immune function as a functional ingredient rather than a nutrient source; MOS is generally considered safe but effectiveness depends on dose and product quality, so consult your veterinarian for pets with specific gastrointestinal issues or special dietary needs.
04
Yucca Schidigera
Yucca schidigera is used in dog and cat foods as a functional additive—its steroidal saponins and polyphenols help reduce fecal odor and ammonia emissions and may offer mild antioxidant or anti‑inflammatory effects. It is not a significant nutrient but is generally safe at typical inclusion levels; however, concentrated supplements or high doses can cause gastrointestinal upset or skin irritation in sensitive animals, so consult your veterinarian before use.
05
Anise Seed
Anise seed is typically used in pet foods and treats as a natural flavoring and mild digestive aid (carminative) to enhance palatability and may help freshen breath in dogs and occasionally in cat products. Because concentrated anise oil can be toxic and some pets—especially cats with limited ability to metabolize certain essential oil compounds—may be sensitive or allergic, anise is used only in small amounts and should be avoided in high concentrations or during pregnancy and lactation; consult your veterinarian if unsure.
