CSJ CP Fat2Fin! - 12.5kg review

46/100Average
DryAdult

A slimming ration that is honest about it from the analysis down, and it sits in our Average band. Fat comes down to 6%, cellulose fills the bowl without much energy, and L-carnitine is printed at 400mg/kg. The starch side does more of the work than we would usually want, which is the trade a low fat recipe makes.

Our view

Likely to suit

  • Dogs on a weight plan, with fibre at 4.5% so the bowl still looks like a meal
  • Owners who want the slimming help itemised
  • Heavier dogs needing joint help: glucosamine and MSM at 400mg/kg each, chondroitin at 200mg/kg
  • Dogs kept off the usual red meats, as fish and duck are the only animals on the list
  • Windy dogs, and the people who share a room with them. Activated charcoal is on the list

Worth watching

  • Rice opens the list, and carbohydrate estimates at 56.0% of dry matter
  • Cellulose fills the dog up but brings none of the nutrition of vegetable fibre
  • White fish meal names no species, and salmon gravy and salmon oil follow it

The score, in context
  1. CSJ CP Fat2Fin! - 12.5kg 46.0

All one Average. Typical dry food: Good.

Slimming foods rarely flatter themselves in general scoring; judged as a controlled ration for a dog who needs to lose a little, it does its job properly.

What's in it
  • RiceOpens the list, ahead of the fish.
  • White fish meal18%Dried, so nearly all of the 18% reaches the kibble. No species named.
  • Oats, barley, potato, sweet potato
  • Beet pulp, duck meal, peasDuck adds a second animal protein without much fat.
  • Salmon gravy, yeast
  • CellulosePurified plant fibre, all but indigestible. A full stomach for very little energy.
  • Rapeseed oil, minerals, carrot, salmon oil
  • Activated charcoalAn unusual sight on a complete food, and the traditional answer to wind.
  • Dried fruits and herbs2000mg/kgSet out name by name, turmeric and devil's claw root among them.
  • Glucosamine, MSM, yucca, chondroitin400, 400 and 200mg/kg for the joints.

L-carnitine at 400mg/kg, taurine at 1,000mg/kg and tryptophan at 2,000mg/kg, with vitamins and a mix of sulphate and chelated trace minerals.

No moisture figure on the label, so our dry matter figures assume the usual 8% for a dry food.

Our daily figure is for holding weight steady, so a dog being slimmed will eat less.

Budget end of the dry market, though the analysis does not quite keep pace with even that price.
