Growling Tums Adult Large Breed review

Our bands put this one in Average, a step under the Good band where the typical adult dry food is found, and the reason is worth understanding before it colours your view. The numbers themselves are perfectly reasonable: protein at 25.0% of dry matter, fat at 15.2% and estimated carbohydrate at 47.3% against a typical 46.2%, which is why nutritional balance reads Average. What pulls the reading down is protein and processing, held to Average because the two animal entries, poultry meal and digest, name no species between them. For a big dog with no dietary history to work around, that is a labelling shortfall rather than a feeding one.

Ingredients, as declared: Poultry meal (min 30%), rice (min 26%), barley, oats, poultry fat, beet pulp, digest, brewers yeast, salmon oil, minerals, vitamins, glucosamine, MSM and chondroitin.

Poultry meal at a minimum of 30% is the largest entry and the source of most of the protein. Drying and grinding come before the mix, so meal holds its weight through cooking. A 30% share is a solid one for a food of this sort. Poultry is the catch, since the word takes in any domestic bird and lets the mix change from batch to batch.

The starch is rice at a minimum of 26%, and barley and oats follow it, with beet pulp adding bulk to the 4.0% fibre. Estimated carbohydrate lands at 47.3% of dry matter, barely above the typical dry food, so for a cereal based recipe the plant side is not running away with the bowl.

The fats are poultry fat and salmon oil, and this is the richest reading in the brand at 14.0% fat and 379 kcal per 100g against a typical 357. That energy density is a genuine advantage for a large dog, since a smaller bowl does the same job, but it also means a quiet week needs the scoop trimmed back.

Digest and brewer's yeast are the palatability entries. Digest is a broken down animal protein sprayed on the outside of the kibble, the trick that makes plain biscuit taste worth eating, and yeast adds B vitamins alongside its savoury note. Neither is a problem in itself, though digest naming no animal is the least informative line on the label.

The joint trio closes the list: glucosamine and chondroitin for cartilage support and MSM for its anti inflammatory reputation, the combination usually chosen for big and ageing frames. No doses are given, which leaves their contribution unknowable from the label alone. The minerals fare better, printed per kilo as iron at 50mg, zinc at 50mg, manganese at 35mg, copper at 15mg, iodine at 1mg and selenium at 0.3mg. Biotin comes in at 150mcg, and the two headline vitamins carry figures of their own.

£3.73 a kilo, sold in 7.5kg, 10kg, 15kg and 20kg bags.

A 15kg adult dog in moderate condition would take about 222 grams a day, or £0.83, from a maintenance estimate of roughly 840 kcal (110 × bodyweight^0.75). A large breed dog will eat well beyond that, so read the figure as a unit rate and not as a portion.
