Hill's Prescription Diet Hills Prescription Diet Metabolic Weight Management Cans review

Ingredients, as declared: Meat and animal derivatives (chicken 3%), cereals, derivatives of vegetable origin, vegetables, eggs and egg derivatives, seeds, oils and fats, minerals.

The list is written almost wholly in category terms. Meat and animal derivatives come first with chicken drawn out at 3%, then cereals, derivatives of vegetable origin, vegetables, eggs and egg derivatives, seeds, oils and fats and minerals. Chicken is the one species named anywhere on it, and egg is the only other animal ingredient you can pick out.

Nothing is broken out here as a digestible core or a named blend. The fibre, the starch and the fat all arrive under headings, and none of them names a source you can follow. If your dog is on an elimination plan, that is a genuine limit on what the tin can tell you, and better raised at the appointment than guessed at.

Crude fibre is declared at 3.4%, which is 14.2% once the water comes out, while fat converts to 12.1% and protein to 28.0%. Carbohydrate is estimated at 39.4% of dry matter and moisture is declared at 76.1%. Fibre up and fat down is precisely how a reducing recipe is put together, so the conversions are showing the intent rather than a thin tin.

Energy is 80 kcal per 100g, and the label also prints metabolisable energy as 811 kcal per kilogram. Calcium works out at 0.75% of dry matter. The dosed minerals are zinc at 26.9mg, iron at 10.5mg, manganese at 2.3mg, copper at 1.7mg and iodine at 0.3mg.

Because each mouthful carries so little energy, the printed portions are large: 93 grams a day at 1kg, 400 grams at 10kg, 485 grams at 20kg and 970 grams at 50kg. The vet running the weight plan is the one to say whether it suits your dog.

It comes in 200g and 370g cans.
