We have a life jacket for our lab/great dane he weighs 115 lbs. He has all the lab water qualities including teh webbed feet, oily skin, and the love to swim. Our issue was he loves to swim so much he gets tired and will not go to shore. In a fear he might drown, we purchased a life vest from Petsmart and he loves it. It keeps him upright and lets him take a break when he needs it.
