Hill's Science Plan: the closer look
The range
Sixty one products, 41 dry and 20 wet. Small and mini formulas cover 33 products and large breed 13. Adult labels run to 52, senior to 29 and puppy to nine. The lists include Adult 1-6, Mature Adult, Healthy Mobility, Perfect Digestion, Perfect Weight and Sensitive Stomach & Skin.
Ingredients
Chicken takes the lead on 46 products. Lamb takes five, turkey and salmon four each, and beef one. Four recipes are flagged grain free. Prebiotic appears on many of the dry labels, and glucosamine and chondroitin on the Mature Adult large breed food.
Nutrition
The wet food runs 5.2 to 8.3% protein as fed with energy of 82 to 121 kcal per 100g. The dry sits at 17.4 to 27.7% protein and 313 to 383 kcal per 100g. Nutritional balance reads Good on 21 products, Average on 22 and Poor on 18.
Strengths
- Protein and processing Good on 31 products
- Breed-size and age formulas throughout
- Joint support flagged on 14 products
Limitations
- Protein and processing reads Poor on 17 products
- Value reads Average on 45 products
- Four grain-free recipes in 61
Where it is less of a fit
- If you want transparency to read higher, check that pillar, as it sits at Good on 54 products
- If you are looking for protein variety, check the labels, since chicken leads on 46 of the 61 recipes
- If raw or fresh is on your shortlist, check the format list, as the range here is dry and wet
Score overview
Protein and processing gives what lift there is, Good on 31 products, but it reads Poor on 17 and that holds the band down. Value reads Average on 45 products and transparency is Good on 54. The puppy and weight-control dry recipes are the ones that reach Good, and most of the wet food reads Average.
The average score is the mean of each product's overall score out of 100 (using the best-scoring variety per product), not a flat average across every variety.
