I have a year old male rottie who likes to follow me back and forth when I clean the bins and cages each morning. I have set a bin down, with the snake still in it, to get another bin, and he just sits there and guards the snake He has never once barked at them or tried to eat one or harm one or even touch one. I think he accepts them as part of his pack and beings to guard along with the rest of us.

That said, I have never gone out of my way to introduce him to the snakes or attempt to have him make friendly with them. I suppose, too, that he has learned to just leave them alone like he does with the rattlesnakes on the ranch
