Skinner's Field & Trial Maintenance Plus review

32.9/100Average
DryAdult

A short kennel recipe in our Average band, with a joint aid supplement written into it. Maize and wheat carry the bowl and poultry meat meal is the animal side. For a steady older working dog on familiar food, it does the job.

Our view

Likely to suit

  • Working dogs whose joints have started to feel the years
  • Kennels feeding one simple ration to several dogs
  • Dogs that eat cereal without complaint
  • A composition you can read start to finish in a few seconds
  • A dog already settled on the brand's plainer maintenance food

Worth watching

  • The joint aid supplement has no breakdown, so no glucosamine or chondroitin amounts
  • Wheat second on the list
  • Poultry meat meal and poultry fat name no bird
  • Protein at 18.0% suits a dog ticking over, less so one working hard through a season

The score, in context
  1. Skinner's Field & Trial Maintenance Plus 32.9

All one Average. Typical dry food: Good.

The score describes the food more than it warns against it: a cereal-led kennel ration with a modest, unnamed animal share.

What's in it
  • MaizeMost of the energy, and a cereal most dogs digest easily.
  • WheatA binder, and the grain that turns up most often in intolerance stories.
  • Poultry meat mealRendered and dried, so third place understates its protein. No bird named.
  • Barley
  • Poultry fatNo species either.
  • Beet pulpFibre, with the barley.
  • Vitamins and minerals
  • Joint aid supplementThe reason this bag exists. One line, no breakdown, no doses.

Vitamins A, D3 and E with trace elements as plain salts and oxides, zinc as the oxide and selenium as sodium selenite.

The joint aid's contents and doses are not on the label. Judge it on how your dog moves after a few months.

Named ingredients

Against the range

Eight entries, two of them cereals at the top. Maize and wheat lead, poultry meat meal is the only animal protein, and barley, poultry fat and beet pulp follow. The last line, a joint aid supplement, is what sets this bag apart from the brand's plainer maintenance food.
