I never owned a cocker, but as a dog groomer I see PLENTY of them.

My observations.

1- they ALL pee when you touch them. Even their owners tell me this.
2- 90% have horrible skin and ears. VERY STINKY. and greasy, and scaly. this could be from the over breeding and not buying a GREAT puppy.
3- the ones with the thinner/lesser hair are less likely to have skin problems, and much more likely to be aggressive.
4- owners are fiercely loyal to their breed, and even after years of horrible skin and innappropriate peeing, they will buy another cocker. (assumption: they are a good companion)

My suggestions:
1- get a mix breed. less likely to inherit the skin problems.
or
2- get a TOP OF THE LINE dog! and ask a million questions about its hertitage.
