We have a new addition to our family a yellow lab that is almost a year old. Had to go through the first Christmas and new year’s, and we were a little concerned as he freaked out at Halloween. So my wife bought this lianzimau dog anxiety jacket calming vest wrap coat, and I could not believe this dog stress relief shirt for our yellow lab worked.The vest relieved her anxiety a lot during the fireworks deluge for new year’s, made with lightweight, breathable, machine-washable fabric a d was very easy to put on “piper” did the trick I could not believe it.
