Hill's Science Plan Puppy Large review

64.4/100Good
DryPuppy

A Good-band puppy food built around keeping a big pup's growth steady, not quick. Calcium is printed and lands inside the range a large skeleton is reared on, the most useful line on the label. Fat is held back and cellulose pads the bowl without adding calories.

Our view

Likely to suit

  • Large-breed puppies, with calcium answered directly at 1.18% of dry matter
  • Owners pacing a big pup's growth on purpose
  • Pups who do well with more fibre, from cellulose and beet pulp
  • Growing dogs that do well on egg. Dried eggs sit high enough to matter

Worth watching

  • Unnamed animal fat and digest beside fish oil and eggs, so no strict exclusion diet
  • Broken rice second and maize third, for a home that avoids grain

The score, in context
  1. Hill's Science Plan Puppy Large 64.4

All one Good. Typical dry food: Good.

On calcium, fat restraint and a fully printed analysis it does the narrow job it sets out to do; cereal outweighing named meat is what holds it level with the typical puppy kibble.

A large-breed pup's ration rises fast, then wants pulling back as growth flattens.

Middle of the dry market and Good value on our scoring, though the price asks a little more than the analysis returns.
