Specific CKD Heart & Kidney Support 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.
Under its CKD banner Specific has a Heart and Kidney Support diet. This is the restricted protein kibble, and the maker directs it at dogs whose vet is managing heart or kidney disease.
Specific's restricted protein kibble from its CKD line, aimed at dogs whose vet is managing heart or kidney disease. Protein is declared at 13.9%, well below an everyday adult kibble, with fat and energy doing the work of holding condition. We do not score veterinary diets, so this page sets out the label and leaves the judgement to your vet.

Our view
Likely to suit
- Dogs whose vet is managing heart or kidney disease and has prescribed a lower protein diet
- A dog that needs to hold condition on less protein, with fat at 15.3% and energy at 390 kcal per 100g
- Owners who want a modest fibre level, 2.4% from beet pulp and cellulose powder
Worth watching
- No phosphorus or sodium figure printed. Those numbers have to come from your vet or from Specific
- Wheat second on the list, and an animal protein hydrolysate that names no species
