Hill's Science Plan Adult 1+ Perfect Weight Large review
A weight-control kibble for the big dog who has outgrown the collar, in our Good band. Energy is held to 317 kcal per 100g against the 357 typical of adult dry food, with fibre pushed up to 11.9% so a measured bowl still fills. The meat leads the list, and the bulk behind it is where the questions sit.

Our view
Likely to suit
- Large adults carrying too much for their frame
- Dogs that beg between meals
- Keeping protein up while calories come down, at 25.1% declared
- Mature and older dogs alike; the label covers both
- Owners who want the birds named and first on the list
Worth watching
- Cellulose, a purified fibre that adds volume and nothing else
- Maize protein meal lifts the protein figure, so not all of it is bird
- Wheat and an unnamed digest and animal fat, which rule it out for an exclusion trial

- Hill's Science Plan Adult 1+ Perfect Weight Large 56.0
All one Good. Typical dry food: Good.
On the analysis alone this is a well aimed weight recipe; what holds the score back is how the bulk is made.

A low-energy kibble takes more grams for the same calories; a 15kg adult wants about 265 grams on the maintenance estimate.
Middle of the market for a dry food, and a little dear for what the analysis shows.
