Hill's Science Plan Adult 1+ Healthy Mobility Large review
A food for big dogs whose joints have started to matter, built on omega 3 instead of a supplement blend. It sits in our Average band. Fish oil is declared at 1.8% with flaxseed just ahead of it, while the meat share is modest at 7% chicken and 11% total poultry.
Our view
Likely to suit
- Large adults and older dogs, with joint-minded feeding built into the everyday meal
- Owners who want the omega source named and given a figure
- Big dogs carrying a shade more than their frame wants. Fat is declared at 12.9%
- One bag for a mature adult and a senior
- Trace minerals each printed with a figure
Worth watching
- No glucosamine or chondroitin dose printed; the joint help is the fish oil and flaxseed
- Fish oil on the list, so not for a dog kept away from fish
- Wheat and maize open the list, with carbohydrate at an estimated 57.2% of dry matter
- Protein at 19.7%, gentle for a large dog in hard work

How this scores
How we scoreThe details
Dog fit

The score, in context
- Hill's Science Plan Adult 1+ Healthy Mobility Large 39.0
All one Average. Typical dry food: Good.
The distance from the middle of the dry shelf comes from how little of the bowl is animal, not from anything a large dog would object to.

- Maize
- Chicken and turkey meal11%Chicken 7% within it. Already dried, so little is lost in cooking.

A large dog scales up well beyond the 15kg daily figure.
Middle of the market for a dry food, and you pay a little more than the analysis alone would justify.
