I've used both products - Personally, I like the anxiety wrap better. It's not nearly as popular or as advertised as the Thundershirt, but I like that it fits behind their tail as well, and I find fits a bit better then the Thundershirt. The problem I've had with both brands is their smallest sizes doesn't fit a small Yorkie very well. Benjamin hated thunderstorms, and I had to make him something similar since at just under 3 lbs, nothing fit him! Lily's close to 6 lbs, so I'm hoping their smallest size actually fits her! Loud noises really spook her since she can't see what's going on, so I'm sure thunder, lighting, fireworks, etc are going to be really scary for her.
