Some dogs react badly to red meat, eggs, soya or dairy without it ever being formally diagnosed as an allergy, and a food built to avoid all four at once is a genuinely useful thing to have on the shelf for that reason alone.

This is made without eggs, soya, dairy or red meat, built on white fish (14%), with fish and fish derivatives, cereals (4%) and chicken (4%) filling out the rest. Protein is notably light at 6%, with oil at just 3%, and it's fed by dog weight rather than a flat scoop.

• White fish 14%, cereals 4%, chicken 4%
• Protein 6%, oil 3%, crude ash 1.5%, crude fibre 0.45%
• Made without eggs, soya, dairy or red meat
• Feeding guide by dog weight, e.g. a 20kg dog gets around 3/4 of a can a day
• 412G tin

On the protein figure. At 6% protein, this is noticeably lighter than most of the wet food on this shelf, built around low fat and fibre for easy digestion rather than a high-protein profile. It suits the dogs it's aimed at, but it's not a like-for-like swap calorie-for-calorie with a richer can.

Who it's for: owners of a dog that reacts to red meat, eggs, soya or dairy, or anyone whose dog does better on a lighter, easily digestible recipe than a typical meat-forward can.
