how does the thundershirt work?

I think it's the same principal that Temple Grandin used to calm down cows and herself (she had autism). It applies light pressure to the chest, stomach, and back of the dog. We ordered it, after noticing that placing a wet and heavy towel on our Bernese Mtn. Dog calmed him down. The Thundershirt though, calms him immediately and doesn't get everything wet!! It's a great buy!! We don't use it everyday....only when he seems under stress (constant panting, destructive behavior, pacing).

how do we figure if this will fit our dog?

they do run a bit small. I bought one of each size because I have multiple dogs. I have two Golden's so I bought the Large for a 70 pound dog and X-Large for a 90 pound dog and they fit great. They should be a little snug but keep in mind that they do run a little smaller. I would say they do not run a whole size smaller though.

Has anyone used it for their dog during a road trip?

I used it for a road trip and my dog was calmer than previous road trips. She tends to get car sick, but with a Dramamine and the Thundershirt she was fine.

I have a shiba inu that is about 25-30 pounds what size should i get?

The most important measurement is the girth or chest size. You want to make sure you get a good snug fit. A chest size of 16"-23" is a small (15-25lbs) and 18"26" is a medium (20-50lbs). Go with the smaller size to ensure a snug fit. Hope this helps!
