Although I agree with the lot of you about proper containment and being held to a higher standard. I do think you are coming down on this person a bit too hard. If she/he could go back and do it all over again I'm sure they would. I know a lot of people on this board don't keep their dogs in the house. If this were an outside dog that had never gotten out before.... Now if the dog had gotten out before than yes I blame the owner 100%. But if it was the first time than I say cut them some slack. They made a mistake, everyone makes them. And don't you think its pretty rediculous that the dog has to be put down because it attacked another dog? Animals will be animals... If a dog can bite a person and walk away with it's life.... and another dog can attack another dog and get a death sentence... what kind of world are we living in?
