Hill's Science Plan Puppy Large review
Hill's Science Plan Puppy Large is built around the single thing large breed rearing turns on, which is keeping growth steady rather than quick. Protein is declared at 29.2%, fat is held back to 15.7% of dry matter, and cellulose adds bulk without calories. Calcium is printed and converts to 1.18% of dry matter, inside the range a big puppy's skeleton is reared on. It sits in our Good band, and the lines a large breed owner reads first are the lines this label gets right.
Our view
Likely to suit
Slowing the growth down is most of the job when your puppy is heading for real size, and this bag was built for it.
- Large breed puppies, whose calcium needs the label answers directly at 1.18% of dry matter
- Owners deliberately pacing a big pup's growth, with fat held to 15.7% of dry matter
- Pups who benefit from more fibre in the bowl, at 2.9% of dry matter with cellulose and beet pulp supplying it
- Growing dogs who do well on egg, since dried eggs sit far enough up this list to matter
Worth watching
Before the first big bag goes in your cupboard, read a few of these entries closely.
- Unnamed animal fat and digest sit alongside fish oil and dried eggs, so this is not the label for a strict exclusion diet
- Broken rice sits second and maize third, so the biscuit is cereal-built, something to note in a household that avoids grain

The score, in context
The overall reading lands in our Good band, level with the typical puppy kibble, and protein and processing, nutritional balance and transparency all read Good with it. Large breed growth is the narrow job this bag is trying to do, and on calcium, on fat restraint and on a fully printed analysis it does it. What pulls the reading down is an ingredients list where cereal outweighs named meat and where the fat and the palatant are given without an animal attached to them.
What's in it
Ingredients, as declared: Chicken and turkey meal (chicken 19%; total poultry 29%), broken rice, maize, digest, animal fat, dried eggs, cellulose, flaxseed, minerals, dried beet pulp, fish oil (1.3%), vegetable oil, oat bran, fructo-oligosaccharides. ActivBiome+ Multi Benefit prebiotic blend (0.6%): Oat bran, fructo-oligosaccharides.

Ingredient notes
First on the list is chicken and turkey meal, declared as 19% chicken within 29% total poultry. It is a dried meal. The water left before the mixer, so the printed share holds up in the finished kibble. Protein converts to 31.7% of dry matter, a solid figure for a growth food.
Calcium is the headline act on any large breed puppy bag, because a big skeleton laid down too quickly is the classic rearing injury. Here the printed figure converts to 1.18% of dry matter, and that lands it inside the window a large breed puppy's growth is planned around. That one line is the most useful thing on the whole label.
Fat is deliberately restrained at 14.4%, or 15.7% of dry matter, and its effect is the same as the calcium's: growth paced rather than pushed along. Energy still lands at 395 kcal per 100g against the 376 typical for the category, so the scoop wants weighing, particularly once a big pup learns to ask.
Cellulose is the entry most worth understanding. Close to indigestible, this purified plant fibre adds bulk and slows a meal down without adding a single calorie. Crude fibre converts to 2.9% of dry matter here. The job gets done well, though the fibre a whole vegetable brings is a different thing altogether. Its presence also tells you how tightly the calories in this bag have been kept in hand.
Broken rice and maize carry the biscuit between them, with carbohydrate converting to an estimated 42.7% of dry matter against a 39.0% typical. Dried eggs sit further up the list than they usually do on a kibble. Egg is a genuinely useful protein to find there, easy to digest and complete across the amino acids a growing dog needs.
The omega fats come from two directions, flaxseed on the plant side and fish oil at 1.3% on the marine. The mineral panel is dosed per kilo, with zinc at 135 mg/kg, iron at 82.2 mg/kg, copper at 8.9 mg/kg, manganese at 8.5 mg/kg, iodine at 2.9 mg/kg and selenium at 0.1 mg/kg. The ActivBiome+ blend at 0.6% is the label's own name for the oat bran and fructo-oligosaccharides that already appear as separate entries.
Price and value
Sold in 2.5kg, 6kg, 12kg and 16kg bags.
A large breed puppy's daily ration rises fast and then wants pulling back as the growth curve flattens out. Weigh against the bag's chart for expected adult weight, and let a hand on the ribs settle it.
