I have wanted a gold cocker since I was eight years old.
When I started looking in November last year, I contacted all the breeders who were listing puppy litters on the Kennel Club website at the time.
Time and again, from both home breeders and professionals, I was told to give serious thought to the "ongoing" and "established" problem of "red rage" - one breeder even said that gold ones are "deservedly infamous" for rage syndrome. Of the thirty four I contacted, I'd say at least 20 of them were negative on the issue, only two or three gave the kind of informed, balanced view you've read on this thread, and the others didn't have an opinion - just didn't have any golds for sale so that was the end of the conversation.
I ended up going to the thirty fourth breeder because she was, at the time, the only one with golden pups available - a few others had goldies, but they were all spoken for. I ended up with her black boy, because Paddy picked me and I love him to bits. Next one in a year or two will be a goldie, come hell or high water. BUT...it still astonishes me that so many people who had gone to the trouble of breeding their girls, so presumably many had also researched the best lines to join for the litter, were so ignorant on the subject. Luckily, (as I was panicking in the face of this onslaught), one of the breeders was involved in one of the Cocker clubs and reinforced what I'd previously read/learnt, so I didn't give up.
I guess a cynic might say they were just trying to induce a novice into taking one of their pups but....
Paddy, solid black, dopey, gentle, loving and sweet as hell.
Go for your goldie! And post some piccies so I can get a vicarious thrill!!!
