ThunderShirt's patented design applies a gentle, constant pressure that has a dramatic calming effect for over 80% of dogs. Using pressure to relieve anxiety in people and animals has been a common practice for years such as swaddling infants and the use of gentle pressure and weighted vests to help people with autism.

NOTE: The ThunderShirt does not necessarily work for all dogs, and its effectiveness largely depends on how anxious or fearful your dog actually is. Consult an appropriately certified canine behaviour consultant or a board-certified veterinary behaviourist for assistance.

Size: XXL - for dogs over 110lbs.
