Hill's Prescription Diet k/d Kidney Care - review & rating
Is Hill's Prescription Diet k/d Kidney Care a good choice?
A therapeutic renal diet - judged in its own category, where restricted phosphorus and moderated protein are clinical goals, not flaws (IRIS guidelines). Decades of feeding trials and published research behind it. Use strictly under veterinary supervision.

ℹ️ This rating is for a specific flavour variant. Brands often sell the same line in several flavours (salmon, lamb, chicken…), each with a different recipe, nutrient profile and allergens - and therefore a different score. Always check the exact variant you are buying.

Pros
- Clinically studied phosphorus restriction (IRIS-aligned)
- Feeding trials and published renal research
- High palatability for a therapeutic diet
- Not for healthy dogs - low protein is intentional and unsuitable
- Premium price
- Requires veterinary recommendation and monitoring
📋 Hands-on test pending - this rating is based on label analysis and public manufacturer data (that is always how we score; a hands-on test adds photos, our own measurements and Bekon’s verdict, but never changes the score).

Frequently asked questions
Can I feed k/d to my healthy dog?
No. Restricted phosphorus and moderated protein serve dogs with diagnosed kidney disease (IRIS staging). For a healthy dog this profile is unnecessarily low in protein. Therapeutic diets belong with a diagnosis and veterinary monitoring.
