Hill's Science Plan Perfect Digestion Adult Small & Mini Dry Dog Food Chicken & Brown Rice review
A small and mini breed kibble aimed at the little dog whose gut has never been predictable, and it sits in our Average band. Fibre is the tool, a deliberate mix of pecan shell, beet pulp, citrus pulp, cranberries and flaxseed. Wheat and maize lead the list, and meat is the thinnest part of the label. If your dog's digestion settles on it, that matters more than any band.
Our view
Likely to suit
- Small and mini adults whose stools have been loose or unreliable
- Owners who want the fibre sources named on the list
- A smaller bag on the shelf, with a 1.5kg size beside the 6kg
- Adult and senior small dogs alike
- Trace minerals printed as doses, zinc at 134 mg and iron at 76.4 mg per kilo
Worth watching
- Wheat and maize open the label, which matters if wheat has caused trouble before
- Maize gluten meal, a plant protein some sensitive dogs handle less comfortably
- Animal fat and digest name no species, so this cannot anchor an elimination trial
