It sure it a sad sad world . I know some people that had a St. Bernard and there was an article in a newspaper about the dog being fed a vegetarian diet and how healthy is was on this diet. Some crackpot read the story and felt 'bad' for the St. Bernard and found out where it lived and poisoned the poor dog .
I met the dog and he was fine looking and not too thin and had plenty of energy . There was no needs for the person to had killed it.
A crackpot could do the same to the OP dog , unfortunately there are crackpots everywhere. I personally feel there should be ban on some dog owners instead of the bred of their dog. The OP T dog is beautiful .
