Rank #2 in Best Grain Free Dog Food 2026: 10 Ranked by Cost per Kilo
Skinner's Field & Trial Grain Free Chicken & Sweet Potato 15kg
Price and rating as shown on Amazon when we collected them. Both change.
Skinner's Field & Trial Grain Free Chicken & Sweet Potato is a 15 kg sack of dry food for adult dogs, made without wheat, maize, barley or oats. It sits at number two in this guide. The rating is 4.6 out of 5 from 621 ratings — high, and in a group where the notes run from 4.3 to 4.8, not high enough on its own to decide anything.
The number that does separate it is the price per kilo. £43.04 for 15 kg works out at £2.87 a kilo, against £8.67 a kilo for the 1.5 kg James Wellbeloved bag in the same guide — roughly three times the price for the same category of food, with no matching three-star gap in the ratings. The 621 ratings break down as 76% five-star, 90% at four stars or better, and 5% at one or two stars; one buyer in twenty was unhappy, and an average of 4.6 flattens that out. The listing is also inconsistent about who the food is for: the spec table recommends it for boxers and gives the dog breed size as "Large", while the bullets say the Field & Trial range covers active and working dogs "of every age, breed and activity level". The same spec table gives the occasion as "Birthday". Everything on this page comes from the Amazon listing, not from any testing we have done.
