Most dogs can swim. Almost no dog can swim once it's tired, panicked, or caught in a current. The PupFloat™ Shark Fin Dog Life Jacket keeps your dog's head above the waterline when their legs give out — and gives you a handle to lift them out in one clean motion.
Who it's for
Short-nosed and heavy-chested breeds sink fastest — French Bulldogs, Pugs, Bulldogs, Boxers, Dachshunds and Corgis all fight their own body shape in water. Puppies and senior dogs tire in minutes. And even strong swimmers get into trouble in surf, currents, or a pool with no shallow end.
If your dog is around water at all — pool days, the lake, the beach, a boat, paddleboarding, or a dock — this is the difference between a swim and an emergency.
📏 Full size chart
Measure the chest. Run a soft tape around the widest part of your dog's ribcage, just behind the front legs. Chest circumference is what determines the size — not weight, not breed.

Between two sizes? Always go up. A slightly loose jacket can be tightened with the straps. A tight one restricts your dog's chest and won't be worn twice. Allow 1–3 cm for measuring variance.

Safety note: a flotation jacket is an aid, not a lifeguard. Always supervise your dog around water, check the fit and buckles before every swim, and introduce the jacket in shallow water first.
