Made for watersports, especially dock diving, this "hot dog" treat bag throws well, floats and is highly visible on the water. Designed for Morgan at K9 Central to “keep the hot dogs out of the dock diving pool filters,” it's made of heavy-duty 600 denier polyester with a waterproof PVC coating and has a core of 4mm (1/4”) water-impervious closed-cell flotation foam. The inner 100% polyester, easy-to-clean waterproof liner wraps over the top edge and closes with a zipper. Measures 11.5cm (4-1/2”) wide, 20cm (8”) long. Carrying handle of 18cm (5”) long, 25mm (1”) polypropylene webbing. Cold water hand wash, hang to dry. TIP: After each training session, rinse the inner pouch with dishwashing detergent or vinegar and a little water, rinse clean and invert to dry. The waterproof liner dries overnight so you'll always have a clean-smelling treat bag.
