Specific CKD-HY Heart & Kidney Support hydrolysed review
We don't put a score on this food. It is a veterinary diet, formulated for a diagnosed condition and meant to be fed on a vet's advice. Your vet has seen your dog and we have not, so a number from us could only pull you towards their advice or away from it, and neither of those is ours to do. What follows is what the label declares, what the analysis works out at, and where to buy it, with no judgement attached to any of it.
Specific offers this one in its CKD-HY range, the hydrolysed version of its heart and kidney diet. It is built on dried potato and hydrolysed salmon, for dogs needing restricted protein and a short list of sources at the same time.
Specific CKD-HY is the hydrolysed version of the brand's heart and kidney diet, for dogs that need restricted protein and a short list of sources at once. We do not put a score on it. Pork fat sits second on the list, a clear sign of where the calories are meant to come from.
Our view
Likely to suit
- Adult dogs whose vet has recommended a restricted-protein heart and kidney diet
- A food trial running alongside a heart or kidney case: hydrolysed salmon is the main protein
- No grain anywhere on the list
- Holding weight on a smaller ration, with fat at 15.5% doing the work
Worth watching
- A second protein hydrolysate and a vegetable oil, neither with a source named
- Salt inside the AuraGuard entry with no amount declared, and no phosphorus figure on the pack
- Portions are the practice's call
