Lol! Sounds about right. Mine will chase the cat around, knock things down, chew on things, bark at everything, chase squirrels, play like it's her job.
Something falls over that wasn't her doing? "Omgwtf everyone HIDE!"
My scaredy-cat dog who jumps at any loud unexpected noise has zero fear of hairdryers. Because I usually pet him while I'm blowdrying, and he loves getting petted so much that he cares zilch about the noise. I swear, that dog would flop on his back on a bed of coals if it meant he was going to get a tummy-rub.
My other dog, who is mostly fearless, HATED the hairdryer. But he wants to pets, too, so he has slowly gotten conditioned to it. Now they both want to come and sit on my feet while I dry my hair.
