Gastrointestinal Biome Wet Dog Food

Overview
Hill's Prescription Diet Gastrointestinal Biome Wet Dog Food is a clinically formulated wet diet designed to support digestive health and foster a balanced gut microbiome in dogs with gastrointestinal sensitivities. Digestive issues — including loose stools, gas, bloating, and inconsistent bowel movements — can become a chronic source of discomfort for affected dogs and frustration for their owners. This formula uses a targeted blend of prebiotic fibres to nourish beneficial gut bacteria and support a healthy, well-functioning digestive system.
Formulated by Hill's nutritionists and veterinarians using ActivBiome+ technology, it works in harmony with the dog's natural gut microbiome to improve stool consistency and overall gastrointestinal wellbeing. The wet format can also help increase water intake, supporting gut motility. Always consult your veterinarian to confirm whether this diet is appropriate for your dog.
