Auggie cares so little about the vacuum that if he's not bringing it a toy to try and get it to play with him (he throws a ball in front of it and the vacuum will "push" the ball for him to chase... yeah... that's Auggie.) he is laying somewhere and even if you prod him with it, he won't get up. You have to yell at him to get up and out of the way. =P
Pepper and Georgie leave the room when we vacuum - I think the noise bothers them. They try to get as far away as they can usually, so I think they are just really sensitive to the noise. They don't seem upset or bothered, they just don't want to be anywhere near it.
If somebody else is running the vacuum, Payton runs to find me and sits and stares at me intently, which is better than when he was a puppy who would run to the vacuum, "look" at it, run back to me going "I LOOKED AT THE VACUUM DID YOU SEE ME WHERE IS MY COOKIE" and then run back to it again, repeat. *facepalm* If I'm running it, I just put him up on a piece of furniture and tell him to stay put and he'll just sit there watching me.
Happy was TERRIFIED of the vacuum though - so knowing that, I took a different approach with the rest of mine. Baby Auggie was gated in the kitchen and got cookies while my mom ran the vacuum eventually right up to the gate while he sat there. P of course got the LAT game. Pepper came to me as she is, and since she just gets up and leaves the room I never worried about her. Pepper gets to do her own things most of the time without too much intervention. =P
But even with Happy who hated it, we would just put him away. It was definitely not "cute" or "funny" like some people treat it. I feel like when people do that stuff, "oh haha he's attacking the vacuum!!" it just encourages it and makes the behavior worse. =/
