Sneyd's Wonderdog Wonderdog Adult Grain Free Salmon & Trout review

Our scoring lands this in the Good band, near the top of the band that the typical adult dry food occupies. The fish is most of the reason. Half the recipe is named animal, the plant side stays short and specific, and almost every working ingredient carries a percentage next to it. Carbohydrate does come out at 48.2% of dry matter, over the 46.2% that adult dry food usually carries. The trace mineral panel names its sources without printing individual amounts. Those two things are what keep it where it is.

Ingredients, as declared: Salmon & Trout 50% (Freshly Prepared Salmon & Trout 36%, Dried Salmon 12%, Salmon Stock 2%), Sweet Potato 24%, Peas 9%, Potato, Beet Pulp, Linseed, Omega-3 Supplement, Minerals, Asparagus 0.3%, Fructooligosaccharides (FOS, 96mg/kg), Mannanoligosaccharides (MOS, 24mg/kg)

Behind the 50% fish headline sit three entries: freshly prepared salmon and trout at 36%, dried salmon at 12%, salmon stock at 2%. That split rewards a slow read. Cooking drives off the water in fresh fish. The dried salmon therefore carries a good share of the protein that reaches the dog. The analysis lands where you would expect from that, with protein converting to 28.3% of dry matter on an assumed 8% moisture, the label not declaring its own.

On the plant side it is sweet potato at 24% first, then peas at 9% and potato. No cereal anywhere. Whole peas bring fibre and antioxidants along with a spread of micronutrients and a little plant protein. At 9% they read as a supporting ingredient. Lifting the protein figure is not what they are there for.

Down in the small print, this label does its real work. FOS at 96mg/kg and MOS at 24mg/kg are prebiotics with a real job, feeding the bacteria that live beyond the small intestine. Both are printed with an amount. Linseed adds plant omega 3 and a useful helping of fibre. Asparagus at 0.3% is the label's flourish and the recipe stands up perfectly well without it.

One entry stays vague, and it is the omega-3 supplement, listed with no source attached. In a recipe built on oily fish it is unlikely to introduce anything the salmon and trout have not already brought, so for most dogs the question never arises. If you are working through a strict exclusion plan with your vet, it is the one line worth asking Sneyd's to name.

Sulphates and oxides are the trace element forms here, and a gut takes those up a little less readily than chelates. The panel names each source and stops there, with no amounts against them. The selenium is the sodium selenite form that the great majority of the trade uses. Vitamins A, D3 and E are all present.

£4.33 a kilo, sold in a 15kg bag.

For a daily guide, a 15kg adult dog in moderate condition works out at about 247 grams, assuming roughly 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate), which comes to £1.07. The bag's own guide asks 140 to 230 grams for a dog of 11kg to 20kg, so use the waistline as the tie breaker.
