You think that porpoise is safe there in the Thames? Really?:-https://www.akc.org/expert-advice/lifestyle/why-your-dog-needs-a-dog-life-jacket/"While some dog breeds are natural swimmers — like retrievers and spaniels — others are less suited to the water. Either way, if you and your pup plan to spend time in or on the water, a dog life jacket is a wise investment. Even good swimmers can tire, have trouble staying buoyant, and struggle to keep their heads above water.Some breeds, such as Bulldogs, have body types less suited to swimming and will need help staying afloat. If your dog accompanies you on a boat, a personal flotation device (PFD) is essential."
