Royal Canin Maxi Sterilised Care review
Written for the big dog whose appetite outlasts the operation, and it sits in our Average band. Fat is held down and fibre lifted, so a smaller ration still fills the bowl, while protein stays up at 30.4% of dry matter. The ingredients list does the deciding: maize first, and an unnamed bird behind it.

Our view
Likely to suit
- Neutered large adults whose appetite has outlasted their calorie needs
- Holding a weight steady, with fat at 13.0% and fibre at 6.7%
- Adults and seniors alike
- Big frames carrying the years, with glucosamine and chondroitin listed
- Dogs that bolt a bowl and look for more
Worth watching
- Maize, wheat and maize gluten carrying much of the bowl
- No bird named behind the poultry protein, and no animal behind the fats
- Glucosamine from hydrolysed crustaceans, and fish oil too

How this scores
How we scoreThe details
Dog fit
Listed for neutered adult and senior dogs; the pack names no breed size, though Maxi is the large range. A neutered dog usually needs a little less than an unneutered one, so let the waistline set the scoop.

Adult, Senior
Poultry
The score, in context
- Royal Canin Maxi Sterilised Care 37.5
All one Average. Typical dry food: Good.
The sterilised design works as described; the reading falls on an ingredients list that opens on cereal and names neither the bird nor the fats.
What's in it
- MaizeThe bag opens on cereal.
- Dehydrated poultry proteinSubstantial with the water already out, but the bird is never named.
- Wheat, maize glutenThe gluten adds plant protein to the figure on the front.
- Vegetable fibresThe weight strategy runs on fibre.
- Hydrolysed animal proteins, animal fatsNeither names an animal.
- Vegetable protein isolateMore plant protein, which a dog uses less well than animal protein.
- Beet pulp, psyllium husks and seedsPsyllium holds water in the gut; beet pulp works on stool quality.
- Fish oil, soya oil, borage oilOmega 3 from the fish; gamma-linolenic acid from the borage.
- Yeasts, minerals, marigold extract
- Hydrolysed crustaceans, hydrolysed cartilageGlucosamine and chondroitin, neither with a dose. The crustaceans are shellfish.
L-carnitine at 200 mg per kilo for a dog that needs to stay trim, every trace mineral dosed, and clinoptilolite, a mineral clay that earns its place in the factory.
Moisture is not declared, so the dry-matter figures rest on an assumed 8%.
Named ingredients
Against the range
One kibble for large dogs after neutering. Maize leads with dehydrated poultry protein second, then wheat and maize gluten. Fat is held to 13.0%, fibre lifted to 6.7%, and L-carnitine dosed at 200 mg per kilo. Moisture is not declared, so the dry-matter figures assume 8%.

Pricing & size
- Price per kilo
- £5.26 (RRP)
- Pack
- 12 kg
- A 15kg dog eats (our estimate)
- 200 to 245 g a day, 225 in the middle
- Cost per day, 15kg dog
- £1.18
Most dogs on this bag will be well over the 15kg reference, so the daily figure for them is higher.
Middle of the market for a dry food, and the price runs ahead of what the analysis shows.
