I board dogs in my home and New Years along with the 4th of July is a tough one. Some dogs are more stressed than others but in my neighborhood it seems to go on for days. Holding and calming up to 3 dogs (my maximum) is not always possible.
I purchased the Thundershirt and it is everything it claims. A couple of my 'thoroughbred' dogs ~aka Terriers... you know who you are :-)~tend to shiver for no particular reason and also if they are nervous or chilled, especially as they age.
Recently an older female rat terrier was here and shivering so I put it on her. Worked like a charm. Snug as a bug in a rug. I even let her sleep in it she was so comfy. It was a matter of seconds and she nestled right down for a nap. She normally will not tolerate wearing a sweater! Her human was thrilled and went right home to order one.
I will be getting more in assorted sizes for the 4th of July and for any of my dogs that need just a little more sense of self assurance. Cookies, milk(bone), story time and Thundershirt for my grand dogs.

PS When you send your dog to be boarded somewhere, or have to leave them home or somewhere else for extended periods,I would recommend using it. You may have to educated the caregiver but they will love it once they see how happy it makes the dog!
Certainly you should make sure of fit and appropriateness for your dog. It is an expensive product. Mine arrived in just a couple of days from placing the order.
