The first and second flaps extend from opposite sides of the central portion and the third flap extends from a central, inner surface area of the central portion. The inner surface is configured to be proximate to the animal's body. The flaps are configured to extend around the animal's mid-body such that the central portion and flaps form a shape conforming to the outside of the animal's mid-body. The third flap may be between the central portion, the second flap, or a combination thereof and the animal's body. The garment may apply pressure to the animal adequate to reduce anxiety, fearfulness, overexcitement, or a combination thereof in the animal.
