Yes sadie is afraid of the vacuum cleaner and will try to get up high (Like the couch) and she will shake. She used to be afraid of other people, the car, just about anything new but she is growing up and is not as afraid any more
Chewy only does this when he smels smoke. When we cook bacon, he hides and shakes like a leaf. I am not sure why he does this... But other then smoke he is fine!
