Overview
Hill's Prescription Diet k/d is a kidney support dry dog food in chicken flavor, sold in an 8.5 lb bag, built around the brand's ActivBiome+ Kidney Defense formulation and an appetite trigger system for dogs with reduced appetite from kidney disease.
This falls under Hill's Prescription Diet line, meaning it's formulated for dogs with a kidney condition diagnosed by a vet rather than as a general wellness food, and Hill's typically requires vet authorization to purchase these formulas.
- 8.5 lb bag
- Chicken flavor, dry kibble
- ActivBiome+ Kidney Defense formula
- Enhanced Appetite Trigger for reduced appetite
Who it's for
Dogs with vet-diagnosed kidney disease needing a controlled diet, particularly medium breed dogs based on the sizing on this bag. Not for healthy dogs without a kidney diagnosis, since restricted nutrient profiles aren't needed and can be counterproductive for normal kidney function.
Pros and cons
- Formulated specifically for kidney support with an appetite trigger for dogs eating less
- Chicken flavor may help appetite in dogs going off food
- 8.5 lb bag size manageable for smaller households
- Prescription diet, likely requires vet authorization to purchase
- Not appropriate for dogs without a kidney diagnosis
Performance notes
The Enhanced Appetite Trigger addresses a common problem in kidney disease, reduced appetite, while the kidney defense formulation is built around the nutrient restrictions, typically lower phosphorus and protein, that vets use to slow kidney disease progression.
