Pero Low Calorie & Gluten Free review
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
- 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.
