I went against conventional wisdom when I got my cockapoo pup, but I went with my gut, and boy did we come out the winners!
First, I went to the internet to get information. There, I found a list of breeders that are trying to standardize this mix. I contacted a few, but fell in love with a breeder in the mid-states that would ship to me. In chatting with her, you could hear her love of all of her dogs and puppies, even though it's her business and she generally has a number of litters at all times. She temperment tests the pups, and trys to keep in touch with as many of her owners as she can. She requests that if you cannot keep the dog for any reason that you contact her so she can place it with another family. And she will only sell to people that are looking for a pet, no middle-men or pet stores. I couldn't visit her farm, but through the listserv, contacted other owners that had gotten their puppies from her. That had visited her. Other breeders on this list thought she and one other breeder were pretty much the tops in the country.
Came time for Clara to come home, and I had a choice of quite a few. She knew the size and color I wanted, so we went through personalities of the individual pups and the personalities of the dogs that she's placed from the parents before. She picked a few, sent me pictures, and we picked from them.
My vet cannot get over how wonderful a personality Clara has. She's exactly what I asked for, easygoing, calms down pretty quickly for a bouncy dog, listens well, and co-operative. And yes, on this list, the owners with the least problems got their dogs from this or a couple other professional breeders.
I know I put myself at risk, but I will never never again trust myself to judge a dogs personality. My old neighbors have a beagle.. we were with them when they picked her out. She's sweet as pie (I would have taken her if I hadn't had an elderly dog then), but neurotic as all get out!!!
Anyway, I disagree that if being a breeder is their business, you shouldn't get a dog there. If you build your reputation on breeding dogs with good personalities, you have more at stake than someone that decides to breed Fifi once or twice. And you have better guarantees, better communication (I still e-chat with my breeder!) and better recourse.
I might have been crazy, but I'd do it all over again!!!
