Judging by the OP’s account, the dog was not dangerously out of control.
You know, I just KNEW it wouldn’t be the dog’s fault.
The dog was obviously feeling threatened by the OP’s presence and was reacting instinctively.
Oh, the poor thing. Can we get it some counselling?
It bit him. It was out of control and dangerous.
I, as a dog owner, would object to the suggestion of euthanasia for something that could be avoided by a little bit of training of the dog and owner.
Bit late now, isn’t it?
Owner should have had the dog under control.
Perhaps they could get a hamster next time?
It’s not like the owner just let their dog continue attacking the OP.
No you’re right, it’s a win/win situation for everyone, isn’t it?
