Our view
Likely to suit
- Medium dogs asked to lose a little while mealtimes still feel normal
- Dogs who follow you round the kitchen between meals. The fibre keeps them fuller for longer
- Stiffening joints, with chondroitin from pork cartilage and glucosamine from crustacean shell
- Older dogs too, as the label covers the senior years
- A household that wants the diet food to be the whole meal
Worth watching
- Fish oil at 1.9%, and a crustacean source for the glucosamine: not one for a dog avoiding fish or shellfish
- Wheat and maize both do real work in the recipe
- This much fibre shows up in the garden for a week or two. Change over gradually and keep water topped up
