Senior Advanced Probiotic Bites Supplement
Verified Jun 15, 2026
This is a soft chew probiotic and prebiotic supplement designed for senior dogs to support healthy digestion and gut flora. It provides a blend of beneficial bacteria strains along with a specialized prebiotic (PreforPro), using chicken-based flavorings to make the chews more palatable. It’s intended as an add-on to a balanced diet for older dogs that may need extra digestive and immune support.
Overall, this is a thoughtfully formulated probiotic supplement for senior dogs, offering multiple well-known probiotic strains plus a targeted prebiotic to support the gut microbiome. The use of chicken-based flavoring helps with palatability, which is helpful for older dogs that can be picky. As with any supplement, it should be used alongside, not instead of, a complete and balanced senior dog food.

At a Glance
KibbleLab Review
Strengths
- Contains a broad-spectrum probiotic blend (including Bacillus subtilis and multiple Lactobacillus species) to support a diverse gut flora in senior dogs.
- Includes a specific prebiotic component (PreforPro) to help nourish and support the activity of the probiotic bacteria.
- Soft chew format is generally easy for senior dogs to chew and can be given like a treat, which helps with compliance.
- Uses familiar food ingredients like pumpkin and flaxseed that can complement digestive health in many dogs.
Considerations
- Uses chicken and chicken organ digest for flavor, so it is not suitable for dogs with known chicken allergies or sensitivities.
- This is a supplement only and does not provide complete and balanced nutrition, so it must be given along with a regular dog food that meets your senior dog’s nutritional needs.
- Any probiotic supplement can occasionally cause temporary gas or stool changes when first introduced, so it’s important to follow the gradual introduction directions.

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.
