Hill's Science Plan Perfect Digestion Large Breed Puppy Food with Chicken & Brown Rice review

61.3/100Good
DryPuppy

A chicken and turkey kibble for large-breed puppies with unsettled digestion. Calcium converts to 1.0% of dry matter, a properly restrained level for a big frame, and that is the figure that earns the name. The poultry is quantified, a five-part prebiotic blend makes up 4%, and cereal carries much of the rest.

Where to buy: coming soon

Our view

Likely to suit

  • Puppies growing into a large frame, with calcium well inside what big-breed growth asks for
  • Pups with easily upset digestion. The prebiotic blend is built in
  • Owners who want the poultry quantified: chicken at 16%, total poultry at 25%
  • Growing dogs that put on condition readily, at 364 kcal per 100g against the 376 typical

Worth watching

  • Maize second and broken rice third, so cereal does a good deal of the building
  • Fish oil in the recipe, beyond the poultry on the front

The score, in context
  1. Hill's Science Plan Perfect Digestion Large Breed Puppy Food with Chicken & Brown Rice 61.3

All one Good. Typical dry food: Good.

An ordinary band over a deliberate brief: the calcium is pitched for a big skeleton, which no band can show.

What's in it
  • Chicken and turkey meal25% poultry, 16% chickenMeal goes in dry, so the printed figure is close to what the kibble holds.
  • Maize, broken riceCereal heavy by design.
  • Animal fat, digestNeither names a species. Digest is the cooked palatant that makes a lean kibble worth finishing.
  • Brown rice4%
  • Barley, oats
  • CellulosePurified fibre, useful for bulk.
  • MineralsCalcium lands at 1.0% of dry matter, the line that matters most here.
  • Pecan shell, flaxseed, beet pulp, citrus pulp, cranberries4% blendThe ActivBiome+ blend: fermentable and bulking fibres together.
  • Fish oil, vegetable oilGenuine marine omega 3; the vegetable oil names no plant.

A large-breed puppy has no steady daily amount: it peaks before the first birthday, then falls away.

Middle of the dry market, and the price runs a little ahead of what the analysis shows.
