Pro Plan Veterinary Diets HA Dry 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.

HA is the hydrolysed diet on Purina's Pro Plan Veterinary Diets list, made for a dog whose vet has put him on an exclusion feeding plan.

DryAdult

Purina's HA is a hydrolysed diet for dogs on an exclusion feeding plan, fed on a vet's advice, and we do not score it. There is no meat on the label. Corn starch and hydrolysed soya protein are the whole concept, the protein broken into fragments.

Our view

Likely to suit

  • Dogs whose vet has put them on an exclusion trial
  • A recipe with no meat ingredient at all
  • Owners who want moisture declared, at 7.5%, so the conversions need no assumption
  • Every size of adult dog, from toy to giant

Worth watching

  • Fish oil in the back half, so something fish-derived reaches the bowl
  • Sugar on the list, marked by the maker as a purified carbohydrate
  • The portion is the practice's call, not the table on the bag

Written by our editorial team. Independent guidance, not veterinary advice.

The details

Dog fit
