The first time I heard of something like this was for one of our pus who now lives up the street. He got very anxious during thunderstorms. He now has a vest that is designed specifically for pets who have this. They put it on him when they first hear thunder and now he is as cool as a cucumber.
Whoops, make that pup.
Yes - I think it is called a thunder jacket.
I know someone who works with a hyper type person. A bunch of people in the group got together and bought the hyper guy a thunder jacket. LOL
