I've never been big on it. Back in the day when I was younger I used to like doing it, but now I have a dog and I'm a little older and I don't do it at all. He's not able to tell me if he wants to or not, so I have no way of knowing if he really likes it or not. I don't care if other people do it to thier pets (it's your pet, care for it as you wish), just don't blow it in my dogs face. At least that's how I do things.
