The Amphibious Mega Ball is perfect for playing fetch in the pool, the lake, or on the beach. Ideal for medium to large dogs, this 5 inch diameter fetch toy was made to satisfy their natural chase instincts in land or water. Features a lightweight EVA foam core, it floats high on the water and won't pop or sink, all while being gentle on your dog's teeth as they fetch the ball. Featuring a high contrast, soft but durable nylon shell, the Amphibious Mega Ball can withstand the harshest fetch conditions.
