Cobbydog Immunity Impact Cold Pressed: Fish Supper with Plasma review
Cobbydog's cold-pressed pellet with plasma added at 5%, and the plasma is the point. It is the protein fraction of blood once the cells are removed, used in weaning and recovery diets for the working proteins it carries. The Duck Dinner reaches our Outstanding band and the Fish Supper our Excellent band.

Our view
Likely to suit
- Owners curious about plasma, declared at a proper 5%
- Dogs that gulp. A pressed pellet breaks down in liquid instead of swelling
- Duck-fed dogs: duck is the Duck Dinner's only named meat
- Fish lovers, with four species itemised in the Fish Supper
- Owners who want doses in front of them
Worth watching
- No animal named for the plasma, so neither recipe suits a strict single-species plan
- Fish oil in the Fish Supper
- Keep the bag closed in a cool, dry bin: there is no hard extruded shell

The score, in context
- Duck Dinner 81.5
- Fish Supper 70.0
Two recipes across Outstanding and Excellent. Typical dry food: Good.
A genuine meat or fish share and figures against what matters keep both above the cold-pressed average; carbohydrate and the unnamed plasma source are what hold them back.
What's in it

The leaner of the pair, for a dog that does well on fish.
Both pellets follow the Cobbydog build: a named meat or fish at the front at 48% or 49%, sweet potato at 32%, peas and beet pulp at 5% each, then plasma at 5%. Two oils at 1.7% each, a vitamin panel with printed doses and a seasoning-level tail of vegetables, fruit, seaweed and herbs finish the list.
The plasma's animal is named on neither label. What varies is the headline protein, the oil (linseed on the duck, fish oil on the fish) and whether calcium is printed, which only the Duck Dinner does.
