Even ” water dogs,” such as chessies, labs, newfies and poodles should wear a lifejacket if they are aboard and you are cruising open water. These breeds ae renown for their ability to swim, but just like an a human being who is an Olympic-class swimmer, they eventually will get tired, or they may get injured in going overboard. If you wont take my word for it, than ask your vet, breeder or another dog expert, like this one.
Of course, just as with first time humans, getting Fido to wear the lifejacket may try your patience, or make you laugh, as this video shows.
Takeaway Portuguese water dogs aren’t just good swimmers… they are excellent divers as well, having been bred to help recover nets.
