I saw a friend on FB mention this and want to see if anyone else use it too and if it actually works. If it does i'd like to get one for Casey he really freaks out when there is thunderstorms and of course fire works too. You should have seen how high he jumped when my cousins were fooling around with some fireworks last year during labor day weekend. Casey ended up jumping on top of my SUV!, so i had to put him in the bathroom in my folks basement hoping that would help him some but he shakes like a leaf. Here is the link that i was looking at http://www.thundershirt.com/lpf/
