To be honest we tried one of those a long time ago. My husband decided the dog was barking to much. It was his idea, so I sent him off to Petsmart to buy his solution. I was having no part of it. He got home, read the directions and secured it to the dog. Yep, it worked! That dog screamed and did a four foot jump and flip but he stuck the landing! Husband took it off right then, brought it in the house and placed it in the junk drawer where it still remains. Needless to say, been there, done that and would never wear the Thsirt.
