Mustang Underdog Foam Flotation PFD - Red/Black - Medium

The Mustang Underdog Foam Flotation PFD in Red/Black Medium is purpose-built for the canine crew member who spends time on deck, in the boat, or around water. Designed by Mustang Survival—a trusted name in marine safety—this dog-specific personal flotation device delivers reliable buoyancy support for your four-legged companion during fishing trips, boating excursions, and waterside adventures. Unlike generic collar flotation, the Underdog's cape-style design distributes flotation evenly across your dog's body, ensuring safety without compromising comfort or mobility.

Built with closed-cell foam flotation, the Mustang Underdog maintains buoyancy even when fully submerged, keeping your dog's head at the proper angle for natural swimming mechanics. The cape-style construction features four adjustment points—neck, chest, and side straps—that secure a snug, customized fit across the medium size range without restricting movement or chafing. The foam core is wrapped in durable, water-resistant fabric that withstands salt spray, freshwater, and extended sun exposure. This thoughtful engineering means your dog can swim naturally while staying afloat, whether in calm inlets or moderate chop.

Anglers and boaters who keep medium-sized dogs on board—Labs, Golden Retrievers, and similar breeds—benefit most from the Underdog's proven flotation and secure fit. The red and black colorway is visible on deck and in the water, adding a safety advantage during low-light conditions or rough seas. Medium sizing accommodates dogs in the 30–50 lb range with proper strap adjustment. Before initial use, verify fit by ensuring two fingers slide comfortably between the neck strap and your dog's collar; adjust all four points for a secure hold that won't slip during water entry or swimming. Coast Guard–approved foam flotation gives confidence knowing your companion meets recognized marine safety standards.
