Royal Canin Gastrointestinal Puppy Ultra Soft Mousse review

We don't put a score on this food. It is a veterinary diet, formulated for a diagnosed condition and meant to be fed on a vet's advice. Your vet has seen your dog and we have not, so a number from us could only pull you towards their advice or away from it, and neither of those is ours to do. What follows is what the label declares, what the analysis works out at, and where to buy it, with no judgement attached to any of it.

Royal Canin offers this mousse within its Gastrointestinal range as the puppy version, a soft textured wet food the maker intends for young dogs whose digestion is being supported by a vet.

WetPuppyAdult

The puppy version of Royal Canin's Gastrointestinal range, a very soft wet food for young dogs whose digestion is being supported by a vet. We leave it unscored. The mousse texture is half the design: it can be syringed or spooned into a pup with no interest in chewing.

Our view

Likely to suit

  • Puppies on a vet-supervised gastrointestinal plan
  • Pups that will not chew, since a mousse can go in by syringe or spoon
  • A growth recipe with calcium in the analysis at 1.58% of dry matter
  • Owners who want the vitamins, taurine and trace minerals printed per kilogram

Worth watching

  • Caseinate is a milk protein, so dairy is in the recipe though the pack never says the word
  • Poultry entries name no bird, leaving chicken, turkey, duck and goose open
  • Fish oil adds a fish element

What's in it
  • Poultry by-productsA category, not a bird.
  • Pork by-products, pork gelatine
  • Rice flour
  • Powder celluloseFibre that mostly stays intact through the gut.
  • MineralsDeclared as a block near the top; the calcium for growth comes from here.
  • Hydrolysed poultry byproductsAgain no bird named.
  • Fish oilA fish element without fish as a meat.
  • CaseinateA milk protein, so the recipe contains dairy.
  • Yeasts, pork blood productsBlood products add colour and protein.
  • Marigold meal

Vitamins D3, E and C with taurine at 1.2g, plus iron, iodine, copper, manganese and zinc per kilogram and clinoptilolite as a technological additive.

The 46.2% and 0.4% figures describe how the protein and fat sources were chosen, not how much meat went in.

Calcium works out at 1.58% of dry matter, the figure to quote to your vet for a fast growing large breed pup.
