Cobbydog Grain Free: Duck & Sweet Potato review
Two grain-free recipes, one led by duck and one by salmon, both in our Good band. Each declares a generous named meat share and swaps cereal for sweet potato and potato. At 391 kcal per 100g they are among the richer kibbles going.
Our view
Likely to suit
- Dogs bored of, or bothered by, everyday chicken and beef dinners
- Grain-avoiding homes
- Ageing or creaky dogs, glucosamine and chondroitin joined by seaweed and linseed
- Busy, active dogs who need a dense bowl
Worth watching
- Chicken oil in both, so neither suits a strict poultry elimination trial
- Fish in both, as the meat in one and salmon oil in the other
- A dog whose main exercise is supervising the kitchen needs measured portions

The duck is listed from puppy to senior, the salmon for adults and seniors, all sizes. Both are dense, so weigh the scoop for a less active dog.

Named ingredients
Against the range
- Meat
- Duck, 26% dehydrated, 18% fresh
- Salmon, 24% and 18%, on the other.
- Life stage
- Puppy to senior
- Adults and seniors on the salmon.
- Salmon oil
- Yes
- The salmon recipe has the fish itself.
- Carbohydrate, dry matter
- 40%
- 38.2% on the salmon.
The one to choose for a puppy, and the higher scorer of the two.
Each recipe pairs a dehydrated meat with a fresh one, the dehydrated share leading, so most of the declared meat has already lost its water. Protein lands a shade over 30% of dry matter in both. Sweet potato and potato do the starch work, chicken oil is the main added fat, and linseed and seaweed meal follow.
A long tail of pumpkin, carrots, apples, tomatoes and a dozen herbs closes both lists, with FOS and MOS prebiotics and glucosamine and chondroitin among them, none dosed. Both run to 391 kcal per 100g.
