There is currently 1 advert for a Cocker Spaniel trained (often listed simply as Cocker Spaniels) on Gun Dogs Hub. Currently advertised at £2,500. The current advert is in Norfolk.
Compact spaniel energy with a strong nose, ideal for flushing and retrieving in the field.
A fully trained Cocker Spaniel should be steady, reliable on recall and delivering to hand under distraction. You are paying a premium for someone else's time, so insist on seeing the dog work in conditions close to your own before agreeing anything. Ask how it has been campaigned, whether it has worked a shoot day, and how it handles other dogs and people. Confirm the dog's own health results too: for this breed, BVA hip scores, an annual eye test, and DNA results for FN, PRA-prcd and AMS.
