Hill's Science Plan Perfect Weight Small & Mini Adult Dog Food with Chicken review
A slimming kibble sized for a small dog's mouth, and the label is upfront about how it gets there. Purified fibre fills the bowl so the ration stays visible while the energy drops. It sits in our Average band, because it is designed to dilute.

Our view
Likely to suit
- A small dog whose collar has been letting out a notch at a time
- Small and mini adults who need fewer calories without their dinners disappearing
- Little jaws. The kibble is made for them
- An older small dog, as adults and seniors share the bag
- Dogs fine on chicken and turkey
Worth watching
- Wheat first on the list, the one thing it cannot work around for a wheat-sensitive dog
- Chicken at 9% within 14% poultry, so maize protein meal carries much of the protein
- Animal fat and digest with no species, and fibre high enough that some dogs take a week or two to settle

Almost every dog on this bag is far smaller than 15kg and on a reduced ration, so the real daily cost is a fraction of the guide.
Middle of the market for a dry food, and you pay more than the analysis alone would justify.
