Specific CJD Joint 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.

Specific lists this one in its CJD Joint Support range as a fish based dry diet for joint management, written around hydrolysed collagen and chondroitin for dogs whose vet is treating stiff or arthritic joints.

DryAdult

A fish-based dry diet from Specific's CJD Joint Support range, written around hydrolysed collagen and chondroitin for dogs whose vet is treating stiff or arthritic joints. Cellulose sits high on the list and fibre is declared at 7.0%, so it reads as a food built to hold a joint patient's weight as much as to feed the joint. We do not score veterinary diets; this page sets out the label and leaves the judgement to your vet.

Our view

Likely to suit

  • Dogs whose vet is managing stiff or arthritic joints
  • A joint patient who needs weight kept in check, with plenty of fibre and L-carnitine on the label
  • Owners who like the joint entries named: PETAGILE collagen, chondroitin sulphate, borage oil, krill

Worth watching

  • Wheat first on the list. If your dog has reacted to wheat before, raise it with your vet
  • No dose printed for any of the joint ingredients
