Hill's Prescription Diet k/d + Mobility Dog Food — canned (Flavoured with Chicken) review

Ingredients, as declared: Meat and animal derivatives (chicken 2%), derivatives of vegetable origin, oils and fats, seeds, various sugars, minerals, molluscs and crustaceans. Protein sources: Pork liver, chicken. ActivBiome+ Kidney Defense prebiotic blend (0.3%): Betaine, oat bran, fructo-oligosaccharides.

Meat and animal derivatives heads the list with chicken shown at 2%, then derivatives of vegetable origin, oils and fats, seeds, various sugars and minerals. Molluscs and crustaceans close it, the customary source of glucosamine in pet food and the entry standing behind the mobility half of the name.

Hill's names two protein sources below the list, pork liver and chicken, so both animals are in the tin even though only chicken carries a printed percentage. Take that to the appointment before the first can is opened, especially where an exclusion plan already keeps one of them out of the bowl.

Hill's puts betaine, oat bran and fructo-oligosaccharides into the kidney prebiotic it calls ActivBiome+ Kidney Defense, declared at 0.3%. Betaine is dosed separately in the additive panel at 1.4g.

With moisture declared at 74.0%, protein converts to 16.5% of dry matter and fat to 22.3%, and the carbohydrate estimate comes to 52.3%. Crude fibre reads 3.5% dried out and calcium 0.77%. Energy is 112 kcal per 100g. These are the proportions a recipe written to a kidney brief is given on purpose, so they belong next to the vet's instructions rather than beside an everyday tin.

Iron is dosed at 17.2mg, zinc at 44.3mg, copper at 2.8mg, manganese at 3.8mg and iodine at 0.6mg, all printed on the label alongside the betaine figure.

The guide begins at 123 grams a day for a 2.5kg dog, gives 530 grams at 20kg and 975 grams at 40kg. Where a maker names two problems on one tin, the printed table gives way to what the practice has worked out for your dog, and the choice to feed it at all stays with them.

It is sold in a 370 g can. On the label's own portions a 15kg dog would eat roughly 750 grams a day, a little over two cans.
