Just at the pet shop and was having the sort of conversation you could only have in a pet shop - farting pets. Everyone else said their dogs were always farting, one women looking after her daughter's 3 labs said they are stinking her home out with the smell. But my dogs rarely fart, Tully actually runs away from her butt and stares at it if she ever releases gas, that's how little it happens. So I wondered if it's what they get fed (the other people were buying low grade food) or if it's because they eat slowly. Or whether Shelties are just too beautiful to pass wind. I'm plumping for the latter.
