Happy Dog Vet Diet: Urinary Low Purine 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.

Happy Dog sells these seven kibbles through its VET Diet line, each named for the condition the maker aims it at. The list runs from Adipositas and Hepatic through Intestinal, Renal and Struvite to Urinary Low Purine, for dogs already working to a vet's plan.

Our view

Likely to suit

  • Dogs already working to a vet's plan for one of the seven named conditions
  • Dogs whose appetite has gone quiet, since every recipe carries a hydrolysed liver coating
  • Owners who want the additive panel itemised. Each variety prints its own
  • A meat-free option in Urinary Low Purine, where egg is the only animal ingredient

Worth watching

  • Some varieties name the species and some print poultry protein or meat meal, so check the one you are handed
  • No moisture or calorie figure on any bag; feed to the vet's instruction first

Taurine at 2000 mg, L-carnitine at 900 mg and L-tryptophan at 1800 mg per kilo, added back into a recipe with no meat to supply them.

No meat at all. For a purine restricted diet that is the point.

The one recipe in the line that sits outside the house pattern entirely.

Six of the seven follow one house pattern: a cereal or potato base, poultry fat as the added fat, dried carrots, potassium and sodium chloride, then a fine tail of botanicals. Hydrolysed liver is on all seven, there to keep a therapeutic kibble worth eating. Urinary Low Purine sits apart, with no meat at all.

Species naming varies: some print chicken or salmon, others poultry protein or meat meal. None declares moisture and the bags print no calorie figure, so dry matter and energy here are estimates. The vitamin and trace element panels are itemised variety by variety.
