Chapel Farm Invest 'N' Digest Grain Free: Duck review
Flavour
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.
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
- Duck 63.9
- 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
- Duck: dried and fresh34% (26%, 8%)Mostly dried, which survives cooking well.
- Dried sweet potatoes, dried potato flakes, dried peas16% each
- Poultry fatSpecies not named.
- Vegetable stock, linseed, dried beet pulp
- Dried brewer's yeast, minerals
- Salmon oil0.5%A trace, but it puts fish on the label.
- Yeast hydrolysate, dried chicory0.5% eachThe prebiotics: MOS, beta glucans, FOS and inulin.
- Yucca schidigera0.03%
Taurine at 1000 mg per kilo and L-carnitine at 500 mg, with the rest of the panel dosed in print.
Poultry fat and salmon oil mean this recipe cannot support a strict single-protein trial.
Named ingredients
Against the range
- Animals on the label
- Duck, unnamed poultry fat, salmon oil
- Salmon only in the original
- Carbohydrate, dry matter
- 44.6%
- 46.9% in the salmon
- L-carnitine
- 500 mg per kilo
- 100 mg in the salmon
The slightly stronger scorer of the two, at the cost of the single-animal claim.
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.
