IAMS Senior Large Complete Dry Dog Food is a 12 kg bag of chicken-flavoured pellets aimed at large and giant breeds, and it takes fourth place in this guide. At £26.45 it works out at £2.20 a kilo, which undercuts both the £3.71/kg bag with the biggest review base here (4.7 stars from 2,313 ratings) and the £4.92/kg bag with the smallest review base. It is still well above the cheapest entry on the list, whose 15 kg bag costs less than this one.

The listing's own numbers repay a close read. The pack claims 78% animal protein, and the same bullet qualifies that as a share of total protein, not a share of the bag. It advertises a 'wheat free recipe' and then, in the asterisk, states that the recipe is produced in a factory which handles wheat. The rating histogram shown adds up to 100, while the listing reports 1,232 ratings, so those bars read as a percentage split rather than counts. Everything on this page comes from the Amazon listing, not from any testing we carried out.
