Hill's Science Plan Adult 1+ Healthy Mobility Medium review

39.1/100Average
DryAdultSenior

The brand's joint-minded recipe in a bag sized for a middling dog. Cereal does the bulk of the carrying, with wheat and maize ahead of 11% total poultry, and the joint help comes from oils: fish oil at 1.8% with flaxseed just ahead. Our scale reads it Average.

Our view

Likely to suit

  • Medium adults and seniors stiffening after a long walk
  • Joint-minded feeding without a separate supplement
  • A marine omega source declared with a percentage
  • Calories reined in a little, fat declared at 13.1%
  • One recipe from mature adulthood into old age

Worth watching

  • No glucosamine or chondroitin dose printed
  • Fish oil, so not for a fish free diet
  • Wheat first, the line to check for a dog with a wheat history
  • Carbohydrate at 57.0% of dry matter against the 46.2% typical
