I have Samoyeds and Bernese Mountain Dogs. I have my dogs to be my pets, show and to work. When I breed I breed with health and longevity, work temperament, and aesthetics in mind... in that order.
My dogs would not be able to compete in agility, conformation, obedience, weight pull, carting, and sledding if it werent for health. If my dog is blind from cataracts it will run into equipment, if my dog has hip dysplasia it will not be able to run, if my dog has a heart or blood disease it simply cannot perform the tasks that I expect from my dogs. As far as longevity I think of my Jammers the Brat. She was a samoyed b*tch that worked until the day she died. She took life seriously and lived it to the fullest. She died at an age of almost 12. If you ask me it was too young. I loved that dog.
The next thing I look at is work ethic. Jammers taught me a thing or two about it she never in her whole life, said "im too tired to do this". She once ran so far that she ran the pads off of her feet (My idiot brother's fault). The next day she limped over to the door. When we told her she couldnt go for a run she was crushed. I laugh when I see the "working" group in the dog show ring on a hot summer day. For those that haven't seen it, it is a sight to behold. All of these "working" dogs all bide for the small snatch of shade that is provided by the all too small tent. I am sorry, but I expect my working dogs to be able to stand in the sun for 45 minutes and show without getting tired.
This brings me to aesthetics. Since I need my dogs to be able to efficiently accomplish the tasks that I give them they should be constructed properly. I see no need to have a dog who is poorly constructed pull my sled, or cart. If a dog is not properly constructed it will simply hurt itself running and slow my team down. My Sam can pull for miles even though he is out of shape. This is because he is constructed in such a way that he can pull with ease. Dogs dont pull sleds or carts with heads. They just dont. I wish judges understood this idea.
I guess I just expect it all.
Jammers the Brat... she taught me a lot about what a dog should be.
