Royal Canin Jack Russell Adult review

44.5/100Average
DryAdultSenior

A small-breed kibble with a dental idea built in: pentasodium triphosphate at 0.35%, a mineral salt that slows tartar on the teeth. Protein is declared at 30.0%. Wheat gluten and maize gluten supply part of that, and with no bird named it sits in our Average band.

Our view

Likely to suit

  • Adult and senior Jack Russells and other small terriers
  • Owners who think about tartar
  • Small dogs with an appetite for protein, at 32.6% of dry matter
  • Homes keeping shellfish away, since the glucosamine is made by fermentation

Worth watching

  • Wheat, wheat gluten and maize gluten carry part of the protein
  • No species named for the poultry, the fats or the hydrolysed proteins, so an elimination trial has nothing to work from
  • Fish oil on the list, and crude fibre low at 1.3%

The score, in context
  1. Royal Canin Jack Russell Adult 44.5

All one Average. Typical dry food: Good.

The analysis reads decently, and the band reflects where the protein comes from and how little the label commits to.

What's in it

  • Rice, maize, wheat
  • Wheat glutenConcentrated cereal protein used to lift the analysis.
  • Animal fats, hydrolysed animal proteinsCould come from anything at all.
  • Beet pulp, maize gluten
  • Minerals, including pentasodium triphosphate0.35%The tartar-slowing salt, and a genuinely useful inclusion for a small breed.
  • Fish oil, soya oilMarine omega 3.
  • Yeast products, fructo-oligo-saccharides, yeastsPrebiotics for the gut.
  • Borage oil, marigold meal0.1% borageGamma-linolenic acid and a plant antioxidant.

Named ingredients

Dehydrated poultry proteins, rice, maize, wheat, wheat gluten*, animal fats, hydrolysed animal proteins, beet pulp, maize gluten, minerals (including pentasodium triphosphate (0.35%)), fish oil, soya oil, yeasts products, fructo-oligosaccharides, yeasts (source of manno-oligosaccharides), borage oil (0.1%), marigold meal, glucosamine from fermentation, hydrolysed cartilage (source of chondroitin). *L.I.P.: protein selected for its very high digestibility.
Against the range

One small-breed kibble led by dehydrated poultry proteins, with rice, maize and wheat behind and two plant glutens lifting the protein figure. No animal entry names a species, and moisture is left off the label, so the dry matter figures assume 8%.

A Jack Russell is a fraction of the 15kg comparison dog, so the smallest bag goes much further than the daily figure suggests.

The premium end for a dry food, and the price runs ahead of what the analysis shows.
