Its a terrible thing thet happened, we dont know the facts. I would not let a 4 year old out of my sight, but to me if a dog kills a child it has to be put down, period. Do I think its the dogs "fault"? of course not, its a dog, not human.I live way in the middle of nowhere and sometimes Bruno and Bella are in a kennel, seperate ones. They are not aggresive dogs but if I lived in a town with people around and I had to leave them in a kennel they would be padlocked becouse you just never know 100% what a dog will do if your not with them.But regaredless whos to blame, there is no place in society for dogs that have killed children.
