Choosing a grain-free food is often about ruling grain out as a possibility rather than confirming it as the actual cause, and a straightforward single-protein recipe like this one is the least complicated way to do that without changing anything else at the same time.

Dried turkey protein leads the ingredient list at 24.5%, though only just — dried potatoes come in right behind at 24.4%. Tomato pomace, dried peas and whole linseed make up the rest. It is a complete grain-free food for adult dogs, and James Wellbeloved's stated approach across the range is to exclude beef, pork, soya, eggs, dairy and wheat.

• Complete grain-free food for adult dogs, built on turkey as the named protein
• Dried turkey protein (24.5%) leads dried potatoes (24.4%) by the narrowest of margins
• Protein 21.4%, fat 10.8%, crude ash 7.3%, crude fibre 3.7%
• Omega-3 at 1.1%, omega-6 at 2.7%
• Glucosamine (0.045%) and chondroitin (0.005%) included
• Excludes beef, pork, soya, eggs, dairy and wheat

A number worth a second look. Turkey is the named protein and does lead the ingredient list, but only just — dried potatoes come in right behind it at 24.4%. Call this an honestly balanced turkey-and-potato recipe rather than a heavily meat-forward one, whatever the name on the front suggests.

Who it's for: adult dogs moving to a grain-free diet as a precaution or on a vet's advice, particularly where turkey hasn't already been tried and ruled out.
