Did you know you could purchase hearing protection for dogs? They are called Mutt Muffs and they look ridiculous. They are designed for dogs that accompany their owners on small planes or motorcycles. They have also helped some dogs with noise phobias. So far I have not challenged Princess Leia.... I mean Reagan with one of her triggers while wearing Mutt Muffs. She has worn them in the car a few times. Sometimes they stay perfectly in place and other times they do not. She does not seem to mind them at all. The company says that a lot of dogs will leave them alone when they realize that they provide relief from loud noises. Reagan is really good about leaving things alone when I outfit her, but they do slip off if she moves her head around nosing for treats. Just a little something to buy the princess.
