Pro Plan Veterinary Diets OM Obesity Management 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.
OM Obesity Management is a high fibre dry diet, and Purina places it under Pro Plan Veterinary Diets for a dog on a weight loss plan set by a vet.
A high fibre dry diet that Purina places under Pro Plan Veterinary Diets, for a dog on a weight loss plan set by a vet. We do not put a score on it. Protein stays up at 31.5% of dry matter while fat is held to 6.5%, which is how the maker keeps a dog fed on fewer calories.
Our view
Likely to suit
- Adult dogs on a vet-set weight loss plan
- A hungry dog: pea hulls and cellulose add bulk without adding energy
- Larger-looking portions, at 296 kcal per 100g
- Owners who want every vitamin and trace mineral dosed on the pack
Worth watching
- Poultry never named to a species, and pork fat beside it, so two animals in the bowl
- Corn, soya meal, barley and wheat gluten all on the list
Written by our editorial team. Independent guidance, not veterinary advice.
