Briantos Maxi Adult review

53.1/100Good
DryAdult

Briantos Maxi Adult is a big-bag, big-dog kibble built on poultry and rice. Dried poultry protein leads at 21%, with 17.5% of the recipe pinned to chicken by name, and rice follows at 20%. Green-lipped mussel extract turns up near the end of the list as a nod to the joints that carry a heavy frame. It comes out in our Good band, the same band the typical adult dry food reaches.

Our view

Likely to suit

Feeding a big dog means thinking about joints and portion sizes early, and this recipe has clearly done some of that thinking for you.

  • Large breed adults, with a feeding table that starts at 20kg and runs all the way to 90kg
  • Owners who like a joint gesture built in, since green-lipped mussel is a recognised natural source of joint-friendly omega 3s
  • Dogs that do well on grain, because rice, barley, maize and millet share the carbohydrate work
  • Chicken-eating dogs, as the label fixes 17.5% of the recipe to chicken by name

Worth watching

Before the first big scoop, give these points a quick once-over.

  • Pork appears mid-list as dried pork protein, easy to miss on a poultry-fronted bag and relevant to any dog kept off it
  • Fish oil, maize and barley all appear, worth knowing for owners steering around any of them

The score, in context

The Good band it earns is exactly where the typical adult dry food also sits, and value is level with that band. Protein and processing and nutritional balance both read Average, transparency reads Poor, and the result is a solidly middling recipe with no standout in either direction. Chicken named at 17.5% gives the label a fixed point many at this level lack, while estimated carbohydrate at 50.2% of dry matter, above the typical 46.2%, and the vaguer entries hold the rest back.

Ingredient notes

The headline works out as 21% dried poultry protein, of which 17.5% is chicken by name. Dried protein is concentrated, so the finished kibble's protein, converting to 26.1% of dry matter, owes most of itself to that entry. The remainder of the poultry, and the poultry fat that follows, never name their birds.

Rice at 20% leads a broad grain bench with barley, maize and millet behind it. Rice and barley digest well, millet is gluten free and easy on most dogs, and maize is the least loved of the group, adequate rather than admirable.

Dried pork protein is a quiet surprise on a poultry-branded label. Pork is a perfectly good and highly palatable meat, but its presence matters to anyone assuming this is a birds-only bowl.

Green-lipped mussel extract is the recipe's signature flourish, best known as a natural anti-inflammatory for arthritic joints. It arrives without a printed dose, so read it as a statement of intent rather than a measured supplement, with fish oil alongside doing steadier omega 3 work.

Beet pulp handles the fibre, dried yeast adds B vitamins, and calcium converts to 1.63% of dry matter, an unremarkable adult level. The additive panel is printed in full, with part of the zinc chelated for better absorption.

Price and value

£2.07 a kilo, in a single 14kg bag size.

A 15kg adult dog in moderate condition would get through roughly 242 grams a day at about £0.50, taking the standard maintenance figure of 840 kcal (110 × bodyweight^0.75) as the basis. The label's own table, written for bigger dogs, allows 245 grams at 20kg rising to 780 grams at 90kg.
