Overview
Hill's Prescription Diet Gastrointestinal Biome is a veterinary dry dog food built around ActivBiome+ technology, sold here as a 27.5 lb chicken-flavor bag for adult dogs with sensitive stomachs.
This is a prescription veterinary diet, meaning it's intended for use under a vet's direction rather than picked up as a general everyday food. Hill's label states it's formulated to help firm loose stool within 24 hours and support the gut microbiome through its prebiotic fiber blend.
- ActivBiome+ technology
- 27.5 lb bag, chicken flavor
- Prebiotic fiber blend
- Veterinary diet for sensitive stomach
Who it's for
Intended for dogs whose vet has recommended a gastrointestinal or microbiome-support diet, not for healthy dogs without a digestive issue. As a prescription formula, check with your vet before switching a dog onto it.
Strengths and trade-offs
Drawn from this product's published specifications.
- Prebiotic fiber blend targets microbiome support
- Large 27.5 lb bag reduces reorder frequency
- Prescription veterinary diet, not a general-purpose food
- Requires vet guidance before switching your dog
Performance notes
The formula's ActivBiome+ approach combines a prebiotic fiber blend with higher omega-3 fatty acid content, aimed at supporting gut microbiome balance alongside the stool-firming effect Hill's lists on the label. Being a dairy-free formula, it also removes one common trigger ingredient for dogs with food sensitivities.
