The Purina Pro Plan Veterinary Supplements FortiFlora Dog Probiotic Supplement stands out as a top choice for managing digestive health in dogs, recommended by veterinarians. The supplement contains Enterococcus Faecium, offering a CFU count of 8 CFU/g, which is beneficial for promoting intestinal health and balance.

The product needs to be stored in a cool, dry place to maintain its efficacy. While the brand Purina has a strong reputation for quality, some users might find the exact nutritional contributions of the strain not as clearly defined as in other supplements. This product remains a reliable option for improving your dog’s digestive health.
