Strong Choice
This is a targeted digestive supplement for senior dogs rather than a complete food, so it should be given in addition to a balanced diet. The formula centers on a diverse mix of probiotics plus a branded prebiotic to support gut bacteria and normal digestion. It’s most suitable for older dogs who tolerate chicken well and may benefit from extra gastrointestinal support.

Strengths
- Contains a wide variety of probiotic strains, which can help support a healthy gut microbiome in senior dogs.
- Includes a branded prebiotic (PreforPro) to nourish beneficial gut bacteria alongside the probiotics.
- Soft chew format is generally easy for senior dogs to chew and can be given like a treat.
- Uses chicken and chicken liver digest for palatability, which can help with acceptance in picky senior dogs.
Considerations
- This is a supplement, not a complete diet, so it must be fed along with a balanced dog food.
- Dogs with known chicken or poultry allergies should avoid this product because it contains chicken and chicken liver digest.
- Pea and garbanzo flours are present; while amounts are small, very sensitive dogs may not tolerate legumes well.
- Probiotic effects can vary from dog to dog, so some seniors may respond more noticeably than others.

Top 5 Ingredients Explained
01
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.
02
Bacillus Subtilis
Bacillus subtilis is a spore-forming probiotic bacterium added to some pet foods and supplements to support healthy gut microbiota, digestion, and stool quality in dogs and cats. It can help with nutrient utilization and immune support, but effects are strain-specific and depend on viability (spores are heat-tolerant); consult your veterinarian before use for animals with weakened immune systems.
03
Bacillus Subtilis DE111
Bacillus subtilis DE111 is a proprietary, spore-forming probiotic strain used in dog and cat foods and supplements to support healthy digestion, help balance intestinal microbiota, and promote regular stool quality. It is heat- and acid-resistant so it can survive processing and passage to the gut, but probiotic effects are strain- and dose-dependent, so choose products with clinically supported amounts and consult your veterinarian—especially for very young, elderly, or immunocompromised pets.
04
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.
05
Lactobacillus Plantarum
Lactobacillus plantarum is a probiotic bacterial strain commonly added to pet foods and supplements to support intestinal microbial balance, aid digestion, and help maintain normal stool quality in dogs and cats. It can promote nutrient absorption and support immune health when provided in adequate, strain-specific doses, but effectiveness depends on viability (CFU count) and formulation, and pet owners should consult their veterinarian—especially for young, elderly, or immunocompromised animals—since probiotics are adjuncts, not replacements for medical treatment.
