Hill's Science Plan Puppy <1 Medium: With Lamb & Rice review

48.8/100Average
DryPuppy

A growth kibble from the brand most owners first meet at the vet's, built to a fixed recipe with a full analysis and a calcium figure you can check. The chicken recipe sits in our Good band and the lamb a step lower in Average. Rice, maize and an unnamed animal fat hold them back.

Our view

Likely to suit

  • Owners who read the calcium line first. Both recipes declare it, inside the growth range
  • Puppies moving onto a brand their vet already stocks
  • Steering off chicken, as the lamb recipe's only named meat is lamb meal
  • A pup better on moderate fat; the chicken recipe is 19.5% of dry matter

Worth watching

  • Rice, maize and maize protein meal all do real work, so a grain-free home should read on
  • Fish oil in both, at 0.5% and 1.4%, if your pup is kept off fish

The score, in context
  1. With Chicken 61.4
  2. With Lamb 48.8

Two recipes across Good and Average. Typical dry food: Good.

Candour is not the issue here; the cereal lean and the unnamed fat are what keep both recipes off the higher places, and the lamb more so.

The animal fat and digest name no species, so lamb is not the only animal behind this food.

The one to choose for a pup kept off poultry, with more plant protein doing the work.

Both recipes lean on rice, with maize and maize protein meal alongside, and both use an animal fat and a digest that name no species. Carbohydrate converts to 40.5% and 38.6% of dry matter, ordinary for a puppy kibble.

Calcium is printed on both and sits inside the growth range: 1.55% and 1.48% of dry matter. Each list closes on flaxseed, fish oil and the ActivBiome+ blend, which is oat bran and fructo-oligosaccharides already listed on their own. What varies is the lead: poultry meal in one, broken rice ahead of lamb meal in the other.

Mid-market for a dry food, though you pay a little more than the analysis alone would earn.
