Alpha Grain-Free Working Dry Dog Food is a 15kg bag of chicken, sweet potato and vegetable kibble, listed at £29.79 and rated 4.4 out of 5 from 83 Amazon ratings. It sits at number 10 in this guide, but the number that decides that is not the star rating. At roughly £1.99 a kilo it is the cheapest bag here — about a quarter of the cost per kilo of the dearest one in the group, where the rating is 4.3 to 4.8 across the board.

The listing is not tidy, and the contradictions are worth knowing before you buy. Two of its five bullet points are word for word the same "skin & coat support" line about linseed. It calls the food "Allergen-Free" in one field while listing "Allergy Relief" as a specific use in another, and it gives the dog breed size as "Medium" while the breed recommendation says "All Breed Sizes". Everything on this page comes from the Amazon listing, not from any testing we have carried out.
