Hill's Science Plan Adult 1-5 Light Large review
Hill's Science Plan Adult 1-5 Light Large rebuilds a large breed recipe around fibre, and that is where the fullness in this light diet comes from. Energy is held to 312 kcal per 100g against the 357 a typical adult dry food carries. It lands in our Average band.
Our view
Likely to suit
- Large breed adults on a weight plan
- Dogs who beg between meals: crude fibre at 12.3% keeps them feeling fed
- Owners who like a number against the bird, with chicken at 9% and total poultry at 14%
- Big dogs with some wear in the joints. Pork cartilage and crustacean shell hydrolysate are both on the list
Worth watching
- Cellulose, there for fullness and not nourishment
- Wheat behind the pea bran, and two fats listed without a source
- Crustacean shell on the list, so not shellfish free

How this scores

Dog fit
Listed for large breed adults. High fibre means bigger and more frequent stools, so a dog with a fixed toilet routine may need an extra garden trip.

The score, in context
- Hill's Science Plan Adult 1-5 Light Large 47.1
All one Average. Typical dry food: Good.
A purified fibre and two unnamed fats cost it on the recipe side, while the analysis does exactly what a light large breed food is meant to do.
What's in it
- Pea bran mealThe fibrous outer coat of the pea, not the whole pea. Bulk with very little energy.
- Chicken and turkey meal14%Chicken printed at 9%. A dried meal concentrates protein, not water.
- Maize, wheat, broken riceWheat is the grain most often blamed when a dog stops agreeing with its dinner.
- Maize protein meal, digestPlant protein.
- CellulosePurified plant fibre, effectively indigestible. Fills a dog up for almost no calories.
- Dried beet pulp
- Vegetable oil, animal fatNeither names a source, so the food cannot anchor an exclusion trial.
