On new years eve, as my dog is very stressed with the fire works, I had three pet remedy plug ins working in the room she was in. They didn't work for my dog, she was just as stressed and agitated with them on. Has anyone else used them and found they work for their dog. Next year I'm going to see if the vet can give her an injection, as don't like to see her so stressed out. She seems to be getting worse with age.
