Used by veterinarians, this is the wrap that calms a canine during stressful situations like thunderstorms or when they are left alone. The wrap exerts a gentle, constant compression around the torso--similar to the sensation of a hug--to help soothe the dog's nervous system and reduce anxiety without sedatives when they hear fireworks or during crating. The wrap conforms to a dog's body and its adjustable Velcro straps provide a snug, comfortable fit while allowing the pet to move and breathe naturally or sleep comfortably. Made from soft, breathable cotton and polyester, the wrap allows air circulation. Machine washable. Sizing determined by the circumference of the dog's chest; select larger size if dog falls into two size ranges: XXL (38"-50").
