Royal Canin Maxi Adult review
The plain everyday member of the Maxi range, in our Average band, for big dogs that need nothing more complicated than dinner. Dehydrated poultry protein leads, wheat flour and maize follow. The thoughtful touch is algal oil, which delivers DHA directly on a food this ordinary.

Our view
Likely to suit
- Large adult dogs on a straightforward daily food
- Dogs between 26kg and 44kg, the span of the label's own chart
- Big dogs that could use some help at the hips
- Shellfish-free households. The glucosamine is made by fermentation
- A manageable bowl for a large dog, at 372 kcal per 100g
Worth watching
- Poultry never narrowed to a bird, so chicken, turkey, duck and goose all stay possible between runs
- Cereal in six separate entries
- Fish oil on the list, so the bowl is not fish free
- Crude fibre at only 1.3%, modest for a dog that does better on a bulkier bowl

The score, in context
- Royal Canin Maxi Adult 43.7
All one Average. Typical dry food: Good.
A label that names its cereals more precisely than its animals, with plant material doing most of the bulk work, holds it a step under the middle of the shelf.
What's in it
- Dehydrated poultry proteinsWater already gone, but poultry covers any domestic bird.
- Wheat flour, maize
- Animal fatsNo animal named.
- Wheat, hydrolysed animal proteinsNo species behind the proteins either.
- Maize flour, maize glutenThe gluten tops up protein with plant material a dog makes less of.
- Dehydrated pork proteinsNamed properly.
- Barley, minerals, beet pulpBarley is the pick of the cereals.
- Soya oil, yeast products, fish oil
- Algal oil (Schizochytrium)Grown, not fished, and delivers DHA directly.
- Glucosamine from fermentation, hydrolysed cartilageNo dose printed, so a helping hand and not a measured supplement.
Every added mineral has a figure, zinc at 127 mg per kilo down to selenium at 0.06 mg, and the clinoptilolite clay is there for the production line.
Named ingredients
Against the range
One everyday kibble for big adult dogs. Dehydrated poultry protein leads, then wheat, maize and barley across six separate entries. Animal fats and hydrolysed animal proteins name no species, while the pork protein further down is named properly. The extras are short: algal oil for DHA, glucosamine from fermentation and chondroitin from cartilage, with every added mineral given a figure.

Pricing & size

The daily figure is for a 15kg dog; the dogs on the pack are much bigger and eat far more.
Middle of the market for a dry food, and the price runs ahead of what the analysis shows.
