Royal Canin Jack Russell Adult review
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%

Named ingredients
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.
