I’ve never heard of this before for people but the local pet food store sells something similar for dogs. I was tempted to try it because one of my dogs is a bit of a stressed out nut case but then I figured it was along the lines of snake oilerie! However, I did notice said problem dog seems to like wearing his winter coat in the house which is made of snug fitting material. So hence I was tempted but decided to save the 60 bucks. Anyway, if it is intended to relieve anxiety I can experiment on the dog for you 
Sorry I not meaning to make fun or anything, the jacket thing seriously crossed my mind for the dog!
