The Full Rundown
The product is well made and actually seems like it would be comfortable for a dog to wear. The robust velcro straps and stretchy material make me think "Lulu Lemon for Dogs" and it would make sense that a dog would feel secure and "hugged" while wearing a Thundershirt. The official website also has an area for adding custom embroidery to the product, and that's a nice touch.
Quality and aesthetics aside, I personally found little to no difference in travelling with a car-nervous dog. And it's actually kind of funny; my dog had a tendency to play the statue game while wearing the thundershirt! It doesn't seem like a restrictive piece of dog clothing at all, but something about it made him want to just stand in one place.
The long and short of it is: this is a high quality product for an actually pretty decent price, and if you've tried everything else for your dog's anxiety, you might as well give it a whirl. Just don't expect night and day results.
