One of the weakest wet foods we have rated. The label keeps too much vague. Feeding it costs about £3.94 a day for a typical adult dog - the breakdown below shows exactly what that buys.

Our analysis

Breaking the 14 down: the biggest single loss is ingredient quality, where it takes 21.7 of a possible 40. On top of that, 25 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 no meat percentage at all, so there is no way to verify how much of the recipe is animal protein, and the ingredient list leans on vague groupings instead of naming what is actually in the bag.

At about £3.94 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 464 g a day = £3.94 / day, £119.78 / 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, 156 kcal/100g, to get the grams above - a denser food needs fewer grams.
  3. Cost: multiply the grams by this food's price, £8.49 / 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
