Chapel Farm Invest 'N' Digest Grain Free review

62.7/100Good
DryAdultSenior

A digestion-first pair in our Good band, built on a short list with no grain. The original holds salmon as its only animal ingredient, which is rare. The duck version scores a touch higher but brings poultry fat with it.

Where to buy: coming soon

Our view

Likely to suit

  • Dogs whose digestion needs a hand, with FOS and MOS both on the label
  • Elimination feeders: the salmon recipe names no animal beyond fish
  • Grain-avoiding homes, since sweet potato, potato and peas carry the starch
  • Maturing dogs. The salmon label covers seniors too

Worth watching

  • Unnamed poultry fat and salmon oil in the duck recipe
  • Starch close to half the dry matter, which suits steady dogs more than hard workers
  • Salmon supplied dried, hydrolysed and as gravy, not fresh

The score, in context
  1. Duck 63.9
  2. Chapel Farm Invest 'N' Digest Grain Free 62.7

All two Good. Typical dry food: Good.

The two keep step, with the duck's small edge coming from its protein and balance readings.

What's in it
  • Salmon: dried, hydrolysed, gravy30% (17%, 7%, 6%)The only animal on the label. Dried fish holds its protein through cooking better than fresh.
  • Sweet potatoes, potato flakes, peas17% eachThese carry the starch.
  • Salmon oil7%A generous omega 3 allowance, the kind that shows in skin and coat.
  • Potato protein, dried beet pulpBeet pulp for gentle fibre.
  • Dried chicory0.5%A source of FOS and inulin.
  • Minerals
  • Yeast hydrolysate, Yucca schidigeraMOS and beta glucans from the yeast.

The bag to buy when one animal in the bowl is the whole point.

Both bags keep grain out and lean on sweet potato, potato flakes and peas at matching shares for the starch. Estimated carbohydrate finishes at 46.9% and 44.6% of dry matter. Chicory and yeast hydrolysate bring the prebiotics, beet pulp the fibre, and taurine is dosed at 1000 mg per kilo in each.

What varies is the animal side: salmon alone in the original, duck with poultry fat and a little salmon oil in the second.

Budget end of the market for a dry food, though on the analysis alone you are paying a little more than it earns.
