I know that their is alot of hard work in showing a dog so for some one to have a pup as a pet not for showing dose it matter that it is mismarked or not.
I think that what 80% of cockers are sold as pets and most of the cockers i see have all their coat clipped of. So the way i see it is that if you are looking for a pet and its a cocker you want then colour is not top of the list.

Not a critisism of any individual but generally - what concerns me is that there is no NEED to breed litters with a risk of mismarking - there are so many dogs that already need homes
Breeders that strive to improve their line and have regard to the breed standards home the majority of their pups to the pet market anyway - and there are thousands of accidental and unwanted puppies every year, without adding further puppies that are bred purely to be pets
COL has really educated me in this; and personally, I would never chose a pup from a litter that had mismarked puppies unless the breeder could explain the reasons why - even though I would be looking for a pet rather than a show-dog
