The vet recommended ThunderShirt has already helped millions of dogs and cats. Proven to be over 80% effective in calming during fireworks, thunderstorms, travel, vet visits, separation anxiety and more! Like swaddling an infant, Thunder Shirt's patented design applies gentle, constant pressure to calm all types of anxiety, fear, and over-excitement issues. 60% polyester, 35% Rayon, 5% spandex Heather grey. NWOT I purchased two different sizes, ended up going with a larger size. Size XS - Velcro allows for custom fit.
