Our test dog Mercy has a hard time dropping the Hydro Plane....it's her favorite fetch toy. Soft but durable high denier polyester fabric wrapped over a ring of high buoyancy foam makes this disc toy the best for fetching at the beach or anywhere there's water or snow. It's slightly oversized, and with the hole in the middle, it's especially easy to pick up. The lightweight, pontoon-like construction floats high atop water and snow for easy visibility and retrieval in any season. Abrasion resistant. Also available in Campfire Orange. Two sizes: 9 in (23 cm), and 12 in (30.5 cm).
