Royal Canin Maxi Adult review
Royal Canin Maxi Adult is the plain everyday member of this range, written for dogs between 26kg and 44kg and not trying to solve anything more complicated than dinner. Dehydrated poultry protein leads the list and wheat flour and maize follow. The useful extras are kept short: algal oil for DHA, glucosamine made by fermentation rather than taken from shellfish, and chondroitin from hydrolysed cartilage. It sits in our Average band, on a label that names its cereals more precisely than it names its animals.
Our view
Likely to suit
If your big dog has nothing in particular that needs fixing, this is the plain member of the range that just gets on with dinner.
- Owners of large adult dogs who want a straightforward daily food, not a recipe aimed at a condition
- Households feeding a dog somewhere between 26kg and 44kg, the span the label's own chart covers
- Big dogs who could do with some help at the hips, with glucosamine and chondroitin both on the list
- Owners keeping shellfish out of the house, since fermentation makes the glucosamine here and no crustacean shells are involved
- Owners who want a manageable bowl for a large dog, at 372 kcal per 100g
Worth watching
Look these label details over before you order the big bag.
- Chicken, turkey, duck and goose all stay possible between production runs, because the poultry is never narrowed to a bird
- Cereal carries a great deal here, with wheat, maize and barley turning up across six separate entries
- Fish oil is one of the entries, so this bowl is not fish free
- Crude fibre is declared at only 1.3%, which is modest for a large dog and worth knowing if yours does better on a bulkier bowl
- No species sits behind the hydrolysed animal proteins or the animal fats, though the dehydrated pork protein further down is named properly

The score, in context
The Average band is where this finishes, with the Good band above it holding the middle of the adult dry category. Two things put it there. Start with the ingredients list: the meat that leads names a family of birds, never one of them, and cereal appears in six different guises. Then there is the shape of the analysis. Protein converts to 28.6% of dry matter and estimated carbohydrate to 42.8%, under the 46.2% typical of adult dry food, though plant material is still doing most of the bulk work. None of that makes it a shaky daily food for a big, settled dog, and the mineral panel behind it is dosed line by line.

Ingredient notes
Dehydrated poultry protein opens the list, which is where you want meat to be, and dehydrated is the useful form of it. With the water already gone, the label's declared share and the kibble's actual share are near enough the same. Poultry is the word to watch: it covers any domestic bird and lets the recipe move between chicken, turkey, duck and goose without a single word changing on the pack. Dehydrated pork protein appears further down and is named properly, which is a small point of clarity worth having.
Wheat flour, maize, wheat, maize flour, maize gluten and barley between them make up the plant side of the bowl. Barley is the pick of that group, cooking down into an easily digested carbohydrate with useful fibre attached. Maize gluten is the entry to note. It tops up the protein figure using plant material, and a dog makes less of that than of the animal kind. The finished numbers come out at protein 28.6% of dry matter and estimated carbohydrate 42.8%.
Animal fats sit high on the list without saying which animal they came from, and soya oil and fish oil follow further down. The genuinely interesting one is algal oil from Schizochytrium, a marine algae that is grown, not fished. It delivers DHA directly, so a dog's body does not have to convert it out of a plant omega. It is a thoughtful inclusion on a food this ordinary.
Glucosamine here comes from fermentation and not from crustacean shells, which is worth knowing if shellfish is off the menu in your household, and chondroitin comes from hydrolysed cartilage. No dose is printed against either, so treat them as a helping hand and not a measured supplement.
The added minerals are all given a figure. Zinc is at 127 mg, manganese at 43 mg, iron at 33 mg, copper at 10 mg, iodine at 3.3 mg and selenium at 0.06 mg per kilo. Above them sit vitamin A at 15800 IU and vitamin D3 at 1000 IU. The clinoptilolite at 10 g per kilo is a naturally occurring clay, and its job belongs to the production line rather than the bowl. Fibre is the one line that reads short at 1.3%, which is roughly what beet pulp on its own leaves you with.
Price and value
£4.55 a kilo, sold in 3kg and 15kg bags.
As a guide, a 15kg adult dog in moderate condition would eat around 226 grams a day at £1.03, assuming roughly 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate). The dogs on the pack are considerably bigger: the label asks 278 grams for a 26kg dog on low activity, rising to 413 grams at 44kg.
