Heh, our current dog is a handful. Shes a little mutt, and one of her parents was apparently a non-domesticated dog. Shes tiny, but weighs nearly 60 pounds, and thats mostly MUSCLE. Shes maybe 1.5-2 feet tall at the shoulder, but we've had problems with her snapping the metal links in her leash/chain. Shes also really damn smart; within about a week and a half of us getting her, she had started shaking hands just from watching people. And within a week of getting back from the philippines, she had learned how to turn the bolt on our door and open it.
Now, on the topic of 'purebreed' dogs, they don't all have to be inbreed. Doberman Pinschers are an example of that, as we used to raise what my dad called 'warlocks' which were dobermans that had no genetic issues all the way up the line, and were pure breeds. Big dogs, anywhere from 120-160 pounds full grown. Of course, unless most dobermans are smaller, that other poster's Doberman/Collie mix is a bit disturbing
. The dog we got, who is a complete moron even compared to the parent breeds is a runt, has a curved spine, some foot issues that I'm not totally sure about, has had to have surgery on her tail 4 times and at age 8 is starting to suffer major arthritis. Maybe she were just unlucky but I still wouldn't want to get one of the purebred dogs from that breeder, heh.
Still, we love our spoiled little moron, even if she busts her tail and sprays blood all over the place every couple of weeks.
We use to have a doberman who was dumb as bricks. Made even the other dogs look a bit small, as he was probably in the 200 pound range... but he was jsut plain stupid. He was really sweet and all, but he would run around the yard, looking over his shoulder to stare at the dogs chasing him... and then plow into a tree. Roughly 18,000$ dog, and we gave him away to a little girl who would come by every day and pet/play with him at the fence, because we couldn't afford to keep taking him to the vet, and he completely adored the little kid.
