My family had bred cockers since before I was born. I was litterally raised with them. The great grandmother of the dogs I have now used to "baby sit me". I used to crawl in with her when she had a litter of pups, chew on her ears, pretty much maul her. Our dogs tolerate a lot from kids. My 2 are actually totally the opposite of the kid haters. They LOVE kids, adult men, not so much. We have bred for years for temperment FIRST, and of course health. We do warn people that cockers are very loyal and can tend to be protective especially of children. Many behavioral issues show up mostly in under socialised dogs. If you keep them away from people other than yourselves they will be more likely to be agressive towards strangers.
Everyone has their own favorite breeds and such. I personally love the cockers, wouldnt have another breed. My girls go just about everywhere with me. The one does have a very slight seperation problem and will howl for about 3 minutes if i leave her at home, but then will go to her favorite past time, Sleeping! But I gotta say I probably created that problem myself by taking her everywhere.
There are good breeders out there. Shop around, ask to see the parents of the pups, check the breeders out. Send me a PM, I can provide you with a couple contacts.
