ZenPet Anxiety Vest for Dogs, X-Small; Help keep your pal calm with the drug-free pressure point therapy of the ZenPet ZenDog Calming Compression Dog Shirt. When worn by your pup, it generates pressure on specific points in your dog’s body that are well-known to help calm stress and soothe anxiety. It’s perfect to use during stressful situations like thunderstorms, crate training, travel, going to the vet or groomer, or for all around nervous pups. Putting it on is easy―simply pull through your pal’s noggin and front legs, and secure the flaps snugly around his chest and belly. Thanks to its breathable, lightweight, four-way stretch fabric, it provides just the right amount of pressure without heating your pal. In fact, it can even be used as a cooling garment when wet.
