Hill's Science Plan Adult 1+ Oral Care review

49.2/100Average
DryAdultSenior

A kibble designed to be bitten into, not shattered, with the whole recipe bent to that purpose. Cellulose sits fourth on the list and gives each piece a fibrous structure, so a tooth sinks in and the surface gets wiped on the way. It sits in our Average band, largely because of the ingredient that makes it work.

Our view

Likely to suit

  • Dogs that will not tolerate a toothbrush
  • A bulkier bowl that satisfies, fibre declared at 9.7%
  • A named meat high on the list: chicken 14% inside 22% total poultry
  • Adults and older dogs alike
  • A gentle hand on weight, energy at 344 kcal per 100g

Worth watching

  • Cellulose fourth, a purified fibre with no food value of its own
  • Dried eggs, which rules it out for an egg-sensitive dog
  • Rewards a dog that chews and does less for one that bolts
  • Animal fat and digest name no animal

The score, in context
  1. Hill's Science Plan Adult 1+ Oral Care 49.2

All one Average. Typical dry food: Good.

The cellulose that lets this kibble wipe a tooth is the thing our scale marks down, and a dog with a dental problem may be glad of the trade.
