Royal Canin Boxer Adult review

39.7/100Average
DryAdultSenior

An unusually rich recipe for a breed kibble, at 20.0% fat and 404 kcal in every 100g, built for a muscular dog that runs all day. It sits in our Average band. Fat is put second on the list on purpose, with L-carnitine at 830 mg per kilo to help the body burn it.

Our view

Likely to suit

  • Busy adult boxers that empty the bowl and ask what happens next
  • Dogs that hold condition better on a fattier bowl
  • L-carnitine printed with a quantity
  • A large adult, with the table running from a 24kg dog to a 38kg one
  • Older boxers, as the label covers seniors too

Worth watching

  • Rice and animal fats ahead of the first meat
  • Pork beside the poultry, and fish oil in the fat blend
  • Poultry and animal fats with no species named, which blunts the label for tracking a sensitivity
  • No moisture declared, so the dry matter figures assume 8%

The score, in context
  1. Royal Canin Boxer Adult 39.7

All one Average. Typical dry food: Good.

Fat and a lower carbohydrate estimate help the balance, but rice first and unnamed animals pull protein and transparency to Poor.

What's in it
  • RiceOpens the list.
  • Animal fatsSecond, for energy density. No species is named, and the source can change between runs.
  • Dehydrated poultry proteinThe first meat, already dried.
  • Maize, vegetable protein isolate
  • Dehydrated pork proteinComparatively rare in kibble, here in a supporting part.
  • Hydrolysed animal proteinsBroken down small, largely for taste.
  • Vegetable fibres, beet pulp, minerals
  • Soya oil, fish oil, copra oilCopra oil, from coconut, is an unusual sight on a dog food list.
  • Dehydrated tomato, hydrolysed yeast, marigold extractAntioxidants, MOS for the gut and lutein.
  • Hydrolysed crustaceans, hydrolysed cartilageGlucosamine and chondroitin with no quantity given. Crustaceans are shellfish.

Vitamins A and D3, iron, iodine, copper, manganese, zinc and selenium all dosed per kilo, with L-carnitine at 830 mg, tea extract at 150 mg and clinoptilolite clay at 10 g.

Pork, poultry, fish and shellfish all appear, so check the list against anything your dog avoids.

Most boxers weigh well over 15kg, so expect to feed more than the guide amount.

Premium end of the market for a dry food, and you pay more than the analysis alone would earn.
