One end has a handle and the other end has a Velcro opening so your water bottle will fit perfectly! These fire hose toys hold up to rough play. Leave your water bottle empty for crunching or fill the water bottle with treats or scenting material, put a few holes in the water bottle to allow the scent to escape and then insert the bottle in the Bottle Tracker, perfect for retrieving and scent training. Not intended for chew toys, best if used outside or on washable surface. Comes in red, yellow, orange, or blue. Approximately 12” long (not including handle) x 4 ¾” wide.
