 If a shelter worker said to me, this dog has a bite history, I'd say, okay, dog's bite. What's the circumstances behind that bite? They would likely say, I don't know, because it's impossible for the truth to be known. But I'm not sure I'd want to adopt that dog either without knowing more information. And you know what happens to that dog? In all likelihood, that dog is deemed unadoptable. And in many U.S. shelters, the dog is destroyed.
