CSJ Fit 'n' Fast review

52.1/100Good
DryAdult

A plain, energy dense kibble of the kind that has fed kennels of working and racing dogs for years, and it sits in our Good band. Salmon leads, cereal follows, and the energy comes out at 385 kcal per 100g against 357 for the typical adult dry food. Fed as the simple ration it was built to be, it does what the name promises.

Our view

Likely to suit

  • Hard running dogs that need energy without bulk
  • Dogs that get on well with fish. Salmon leads the recipe and salmon oil backs it up further down
  • A kennel feeding several dogs the same simple ration from one 15kg sack
  • Settled, unfussy digestions, since beet pulp and yeast are the only concessions to a delicate stomach

Worth watching

  • Maize gluten lifting the protein figure, with carbohydrate estimated at 51.7% of dry matter against 46.2% typical
  • Chicken fat and chicken gravy on the list, so a fish led recipe is not fish only

The score, in context
  1. CSJ Fit 'n' Fast 52.1

All one Good. Typical dry food: Good.

A general score cannot see the job this was built for, and as a simple ration for a dog in hard work it does that job.

What's in it
  • SalmonFirst by weight going in, but fresh fish loses much of its water in cooking, and with no percentage there is no pinning down what is left.
  • Maize, barley, oatsThe biscuit. Barley and oats bring fibre and a steadier release of energy.
  • Chicken fat, chicken gravyPoultry in a fish led recipe.
  • Beet pulpFermentable fibre to keep digestion regular.
  • Linseed
  • Maize glutenA milled by-product used to top up protein without more meat. A dog gets less from it than from an animal source.
  • Minerals, salmon oilSalmon oil gives the marine omega 3 a dog can use directly.
  • YeastMannan oligosaccharides, a prebiotic.
  • Dried fruits and herbs1000mg/kgEvery plant named, blackcurrant to marjoram. At that total it is a flourish, not a working dose.
  • Yucca schidigeraFor stool odour.

Iron, copper, zinc and manganese each come in two forms, a sulphate alongside an amino acid chelate, with selenium as sodium selenite.

No percentage against any ingredient, so the salmon at the front cannot be measured.

Against the range

One recipe, salmon first with maize, barley and oats behind it, and not a single percentage on the list. Protein finishes at 25.6% of dry matter and fat at 13.3%, with maize gluten topping up the protein figure from plant material.

Hard work asks for the upper end of the daily range.

Budget end of the market for a dry food, though you are paying a premium for what the analysis shows.
