Dr John Silver review

42.6/100Average
DryAdultSenior

Two light, low fat everyday kibbles for adult and senior dogs, both in our Average band. That reading is about how thin the animal share is, and much less about the bowl in front of your dog. Wheat leads each recipe, with a meat meal declaring 11% chicken or beef behind it.

Our view

Likely to suit

  • Less active adults and seniors, with fat at 6.0%
  • Dogs that have eaten wheat all their lives without bother
  • Several dogs of different sizes on one bag
  • A choice of poultry or beef on the same build

Worth watching

  • Wheat first in both, so a wheat intolerance rules them out
  • Neither meal names its species beyond the 11%, and the beef carries chicken too
  • A dog in real work will want more fat than these give

The score, in context
  1. Dr John Silver 42.6
  2. Beef 42.1

All two Average. Typical dry food: Good.

A cereal-led food with a meat contribution, still serviceable for a small, steady, older dog and honest about being simple.

Poultry from top to bottom, and the more cereal-heavy of the pair.

Both recipes open on wheat and put a dried meat meal second, each declaring 11% of its named animal with the rest of the meal unidentified. Peas at 4% sit inside a vegetables heading, and linseed and yucca extract close both lists.

Fat is 6.0% in each, protein converts to under 20% of dry matter and carbohydrate to 63.6% to 65.4%. The beef adds chicken fat and chicken gravy, so poultry runs through both.
