Hi Jane - yes - I have tried one mixed breeding - although I do breed my workers with the breed standard in mind as well as the other things needed in a worker, so therefore in the main I dont have overlong backs etc, my reason for bringing show blood (parti-colour - strong Normanview breeding) was to try and keep the 'cockery' type (i dont like the springery type of working cocker that I see so often - we wont even go there!!) and put a better head on. What was interesting was that physically they all looked like show cockers but with less length of coat. 2 had totally correct ear sets, the other 2 were passable. They had lovely silky hair, very little puppy coat (my workers have no fluff to strip out) but more glamorous than the working strain. One esp was a very nice dog pup. On seeing them now, they are like show cockers of the 50s/60s with coat, but not as much as todays. However, Stella only gave me one girl and she wasnt good enough to keep as I felt she lacked bone - I like them v sturdy!! I ran her on for 8 months and homed her with a known home who have Stella's sister. I dont know if I will try it again though, the pups are as bright as buttons with a couple doing obedience. If I could have kept the best dog pup I would have, but having a v dominant male setter who doesnt like another boys on his patch, it was a no go.
