Royal Canin Rottweiler Adult review

39.6/100Average
DryAdultSenior

A big bag for a big dog, with the extras reading like rottweiler worries answered one by one. It sits in our Average band because the list names almost nothing. The analysis behind it is better balanced than the list suggests.

Our view

Likely to suit

  • Adult rottweilers and other giant breeds, the size the feeding table is pitched at
  • Big dogs feeling their years, glucosamine and chondroitin both on the list
  • Keeping a heavy dog trim, with L-carnitine at 830 mg per kilo
  • Active and working adults, fat at 20.0% carrying the energy
  • Dogs that do well on poultry and rice

Worth watching

  • Glucosamine from hydrolysed crustaceans, which matters in a shellfish-avoiding home
  • Fish oil part way down the list
  • Poultry, fats and hydrolysed proteins all named by family, so it cannot prove or clear a single protein

The score, in context
  1. Royal Canin Rottweiler Adult 39.6

All one Average. Typical dry food: Good.

The band is a verdict on transparency more than substance: nutritional balance reads Good while protein and processing reads Poor.

What's in it
  • RiceFirst, and where the calories start.
  • Dehydrated poultry proteinWater already out, so the declared weight is close to what reaches the bowl. No bird named.
  • Animal fatsNo animal named.
  • Vegetable protein isolate, maizePlant protein doing some of the work the meat gets credit for.
  • Hydrolysed animal proteins
  • Vegetable fibres, beet pulp
  • Fish oil, soya oil
  • Minerals, dehydrated tomato, hydrolysed yeastAntioxidants from the tomato, a prebiotic from the yeast.
  • Hydrolysed crustaceans, hydrolysed cartilageSources of glucosamine and chondroitin, with no dose printed.
  • Marigold extract

Vitamins A and D3 and trace minerals with doses, L-carnitine at 830 mg to help turn stored fat into energy, and tea extract at 150 mg for polyphenols.

The glucosamine comes from crustaceans, so not for a household avoiding shellfish.

Named ingredients

Rice, dehydrated poultry protein, animal fats, vegetable protein isolate*, maize, hydrolysed animal proteins, vegetable fibres, fish oil, beet pulp, soya oil, minerals, dehydrated tomato, hydrolysed yeast (source of manno-oligo-saccharides), hydrolysed crustaceans (source of glucosamine), marigold extract (source of lutein), hydrolysed cartilage (source of chondroitin).
Against the range

One recipe for big adults: rice first, dehydrated poultry protein second, animal fats third, then vegetable protein isolate and maize. Fat is set at 20.0%, L-carnitine is dosed at 830 mg per kilo, and glucosamine and chondroitin come from hydrolysed crustaceans and cartilage. Moisture is not declared.

A rottweiler eats far more than the 275 grams a day a 15 kg dog would, so scale the cost to your dog.

Middle of the market for a dry food, and the price runs ahead of what the analysis shows.
