Pero Low Calorie & Gluten Free review

59/100Good
DryAdultSenior

A lighter fish kibble in our Good band for adults and seniors with a little to lose. The calorie cut is gentle: energy at 339 kcal per 100g against 357 for the typical adult dry food, so the bowl still looks full. Brown rice at 40% comes in ahead of the fish.

Our view

Likely to suit

  • Adult and senior dogs carrying a few extra pounds
  • Stomachs that suit fish
  • Gluten kept out
  • Stiffening joints, with glucosamine at 175 mg per kilo on the label
  • Owners who read mineral panels, since selenium is the organic form here
  • Holding muscle while weight comes off, with protein at 26.1% of dry matter

Worth watching

  • Chicken gravy on the list, so it is not fish only
  • Fish meal at 8% names no species
  • Hydrolysed salmon mainly buys flavour, so the 33% is not all whole fish

The score, in context
  1. Pero Low Calorie & Gluten Free 59.0

All one Good. Typical dry food: Good.

A properly declared fish share and figures on the joint support lift it; no single fault holds it back, only a recipe headed by rice.

What's in it
  • Brown rice40%The biggest single entry, and no gluten.
  • Salmon meal14%The concentrated form, doing most of the protein work.
  • Fish meal8%No species named, though still a good source of marine amino acids.
  • Hydrolysed salmon11%Pre-broken protein, mainly for flavour.
  • Beet pulpKeeps digestion regular while the ration is trimmed.
  • Salmon oil5%The omega 3 source.
  • Sweet potato, flaked potato
  • Chicken gravyA small amount for taste, and the end of any chicken free claim.
  • Minerals, krill
  • Glucosamine, chondroitin sulphate, cranberry175mg/kg, 80mg/kg, 80mg/kg

Selenium as organic selenium, the form more readily used and the less common one on this shelf, with zinc at 100mg per kilo.

Chicken gravy keeps it off a fish-only elimination trial.

Named ingredients

Against the range

One rice-led fish recipe. Fish at 33% is split into salmon meal, fish meal and hydrolysed salmon, with salmon oil and krill behind. Brown rice, sweet potato and flaked potato carry the starch, and there is no gluten.
