Sadly, it is as Tanza said in most rescue organizations and shelters. There is too much liability in adopting out a 'known biter.'
This is how I got my American Eskimo. He was brought to the vet clinic (where I worked) for rabies observation, as a stray. He had bitten at least one neighborhood child while stray. (edited to add: This was a dog that had been starved half to death, teased with food and hit with sticks, left on the street to fend for himself.) After his 10 day observation period was up, I asked what would become of him. I was told, "since he has a history of biting, and no one is claiming him, the shelter will put him down." This was a 2 year old dog, purebred, beautiful, who had obedience training done on him at some time in the past. Someone paid for him, and took time to teach him….
I broke into tears (at my JOB:eek:) and begged my boss not to let it happen. I got a lecture about not saving every dog. I sobbed that I didn't want to save every dog, but I had to save THIS ONE. My boss and his wife worked some serious magic with the local humane society, I signed a wavier, and brought Snowy home. He was my best friend, protector and companion for over 13 years after that.
But someone had to be willing to take a chance on him....It was one of the best chances I ever took.
