The cotton canvas water bottle sleeve with velcro closure has double-stitched seams for added durability.  The dog toy measures 11" x 5", allowing room for an empty gatorade bottle. Dogs enjoy the crinkle sound of an empty water bottle. As it gets crushed, simply open the sleeve and replace the empty water bottle. Wash in cold water by hand or in machine. Air dry or tumble dry on low. As with most dog toys, recommended to use with supervision. Water bottle NOT included.
