Royal Canin Maxi Joint Care Adult review

35.5/100Average
DryAdultSenior

An Average joint-care kibble for the biggest dogs in the house. Hydrolysed collagen is declared at 0.84%, chondroitin comes from hydrolysed cartilage, and green tea extract is dosed at 2.5 g per kilo. Around them sits a maize-led recipe with fibre lifted to keep a big appetite occupied.

Our view

Likely to suit

  • Giant breed adults whose joints are showing their mileage
  • Seniors as much as adults; the bag covers both
  • A big dog that needs to stay lean, with crude fibre at 6.3% and fat held to 15.0%
  • An antioxidant with a printed dose, green tea extract
  • Heavy dogs that eat quickly, since high fibre gives the bowl staying power

Worth watching

  • No glucosamine on the list: the joint support is collagen and chondroitin, neither with a printed dose
  • Maize leads, with wheat, maize flour and maize gluten behind
  • Poultry protein, animal fats and hydrolysed proteins name no species
  • Fish oil, so not for a fish-free diet

The score, in context
  1. Royal Canin Maxi Joint Care Adult 35.5

All one Average. Typical dry food: Good.

Most of the distance to the typical dry food is about naming; read as a joint food for a giant breed that eats it happily, it does what it set out to do.

What's in it
  • MaizeFirst in the bag; a cereal-led recipe.
  • Dehydrated poultry proteinWater out before mixing, so it does real work. Poultry names no bird.
  • Wheat, animal fatsThe fats name no animal.
  • Vegetable fibresHigh on the list, the quiet feature.
  • Vegetable protein isolate, maize flour, ricePlant protein raising the figure, which a dog handles less well than meat.
  • Hydrolysed animal proteins, maize gluten
  • Beet pulpA reliable friend to stool quality.
  • Fish oil, yeasts, minerals, soya oilOmega 3 from the fish oil.
  • Hydrolysed collagen0.84%Supplies the amino acids cartilage is built from.
  • Marigold extract, hydrolysed cartilageLutein, and chondroitin.

Vitamins A and D3 with iron, iodine, copper, manganese, zinc and selenium, each dosed, plus green tea extract at 2.5 g and clinoptilolite at 10 g per kilo.

Moisture is left off the pack, so the dry matter figures assume 8%.

The dogs on this label are far bigger than 15kg, so expect the daily share to be well above the estimate for a mid-sized dog.
