Wolf Of Wilderness Dry Junior: Wild Hills review

All three recipes settle in our Good band, and so does the typical adult dry food. The spread is no mystery once you read the lists. Blue River declares more protein than the other two, with dried salmon protein at 10% behind its fresh chicken. Wild Hills spreads its animal content across chicken, duck and a hydrolysed liver palatant. Green Fields leans harder on pea protein and poultry fat, and its pillars come back Good for protein and processing, for nutritional balance and for value, with transparency a step up at Excellent. Treat the difference as construction rather than as a warning; these are recognisably the same food, built with different care.

Ingredients, as declared: Fresh chicken meat (26%), potato flakes, peas, chicken protein (12%), poultry fat (5%), partially dried and hydrolysed poultry protein (5%), duck protein (4%), linseed, dried apple pulp, brewer's yeast, hydrolysed liver (2%), salmon oil, pea flour, dried sea buckthorn (0.2%), dried wild berries (0.1% blueberries, 0.1% cranberries), dried wild herbs (0.1% thyme, 0.1% rosemary), dried ginger root (0.1%), glucosamine, chondroitin sulphate, mannan-oligosaccharides, inulin, Mojave yucca.

Fresh chicken opens every label, at 33% on Blue River, 26% on Wild Hills and 25% on Green Fields, and Blue River's is stated as free-range. Much of that fresh weight leaves as steam in the oven, so the dried entry behind it matters just as much. Blue River puts poultry protein at 18% and dried salmon protein at 10% there, and Wild Hills chicken protein at 12% with poultry and duck proteins behind it. Green Fields has poultry protein at 15% with dried lamb protein at 4%. Protein converts to 33.7% of dry matter on Blue River and 32.6% on the other two.

Potato flakes bind all three recipes and nothing cereal appears anywhere. Peas and pea flour turn up in Wild Hills, pea protein in Green Fields. Read that last one twice: refined pea protein pushes the protein figure up without putting any more animal in the bowl.

Joint support is the clearest split in the range. Blue River prints glucosamine at 0.04% and chondroitin sulphate at 0.02%, Wild Hills lists both without percentages beside them, and Green Fields carries neither. For a large-breed pup whose frame is going to ask a lot of its joints later, that is a real difference between the bags.

The extras are where the range shows its character. Wild Hills adds hydrolysed liver at 2% purely to keep the bowl interesting, then sea buckthorn at 0.2%, ginger root at 0.1% and Mojave yucca. Yucca is there for the smell of what the garden gets. Blue River works algae meal at 0.1% in as a marine source, and all three lean on brewer's yeast for B vitamins and on yeast cell walls at 0.2% for the prebiotic fraction.

The wild berries at 0.3% and the herb blends at 0.2% are the range's flourish. They give the labels their character and they do no harm, but a puppy grows on the meat, the minerals and the fat, not on the camomile.

The trace minerals come mostly as sulphates with a chelated zinc alongside, the form that tends to be absorbed better of the two. Selenium is declared as sodium selenite, the commoner of the two selenium forms permitted here; the yeast-bound version is usually better absorbed, and plenty of well-made foods use the selenite regardless.

The most varied bowl of the set: chicken at 26% fresh with chicken protein at 12%, then hydrolysed poultry protein at 5% and duck protein at 4%, with hydrolysed liver at 2% for palatability. Sea buckthorn, ginger and Mojave yucca fill out the tail, and glucosamine and chondroitin are both listed, though without doses printed beside them.

Blue River is £3.50 a kilo, with Green Fields and Wild Hills both at £4.17.

As a guide, a 15kg dog in moderate condition eats about 220 grams a day of Green Fields or Wild Hills. That works out at £0.92, assuming around 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate). A growing puppy eats more than that against its bodyweight, so treat the figure as a starting point and go by the label's chart for the adult weight you are expecting.
