I'm not really taking sides on this one, but...if I might add a story. I know this is about a pit and not a lhasa, but nonetheless...

I work at a vet clinic near downtown Tampa...I see a lot of aggressive dogs and such. We have a county animal shelter, that health tests and behavior tests dogs, and if they don't pass any of these tests they will be put down. However, recently they have started construction on the shelter to create more kennels. A guy brought in a very large pit, that was not neutered or anything. He said that he was there working with the construction crew and was walking through the euthanasia row and saw the dog there, about to be euthanized. Somehow someone let him just take the dog off the premises. So he brought him in to get tested and to get heartworm tested and such. I got someone to hold the dog to pull the blood...he gave me his paw, I put a little bit of alcohol on the leg (just got it wet a bit) and the dog FLIPPED. If the girl holding him had not had a good grip on the dog, I would have lost an arm and probably part of my face. We put a muzzle on him and I tried to hold him (the other girl is smaller than me) and he ripped open my arm with his nails. So we had to get the biggest guy there to hold him, and he even had a difficult time. All this happened with just the alcohol on it's leg...we hadn't even poked him with the needle. And he ended up being heartworm positive.

Now you tell me what happens when the one day that guy has a child at his house, whether it be his, his nephew or niece, or even an adult that dosen't know dogs, and they tick that dog off. The dog is a time bomb. Granted, it's not a lhasa, but...I understand what's going through the person at the shelter's mind. There are too many unwanted nice dogs, for people to be taking home ticking time bombs.
