My pet had recurring digestive discomfort, and after consulting with our vet, we decided to try a prescription diet. What stood out to me was the inclusion of prebiotic fibers and highly digestible protein sources in this formula.

  • Monitor your pet’s response during the transition and afterward, and keep your vet informed of any concerns.
  • This diet is designed for specific gastrointestinal conditions, so it might not be necessary if your pet is healthy.
