Hill’s Prescription Diet Canine Gastrointestinal Biome Stew - Chicken review

A weak wet food by the label. Just 8% declared meat content, and the label keeps too much vague. Feeding it costs about £8.55 a day for a typical adult dog - the breakdown below shows exactly what that buys.

Our analysis

Breaking the 39 down: the biggest single loss is ingredient quality, where it takes 24.1 of a possible 40. Its strongest showing is additives at 9.3 of 10. On top of that, 16 points are deducted outright for red-flag ingredients - a penalty applied before anything else is counted, which is why the total lands where it does.

The label declares 8% meat, which is a low figure, and a declared low figure is still more honest than silence, and the ingredient list leans on vague groupings instead of naming what is actually in the bag.

At about £8.55 a day to feed a 15kg dog, the question is not whether it is cheap but whether the label justifies the price - and on our scoring, it does not.

How heavy is your dog?

A typical 15 kg adult dog needs about 872 g a day = £8.55 / day, £259.92 / month.

How we work this out
  1. Energy: an adult dog at rest needs about 95 × weight0.75 kcal a day (the FEDIAF maintenance formula - a 15 kg dog works out near 725 kcal).
  2. Portion: divide that by this food's energy density, 83 kcal/100g, to get the grams above - a denser food needs fewer grams.
  3. Cost: multiply the grams by this food's price, £9.80 / kg, for the daily cost, then by 30.4 days for the month.

Estimates scale to your dog's weight and the food's calorie density - a denser food needs fewer grams. A rough guide; always follow the pack. Try the full feeding calculator
