Does my dog need a life jacket for swimming?

Open water with currents, boating trips, and unfamiliar swimming spots with unknown depth or hidden hazards all raise the value of a life jacket considerably compared to a shallow, calm, and familiar paddling area a dog already knows well. A jacket also matters for a dog swimming in cold water, since fatigue and reduced coordination set in faster in cold conditions than in a warm pool or lake.

Brachycephalic breeds like Bulldogs and Pugs, along with heavy-bodied, short-legged breeds such as Dachshunds and Basset Hounds, generally do not swim as naturally or efficiently as breeds built for it, often tiring faster and struggling more to keep their head above water, which makes a life jacket a sensible standard precaution for these groups rather than an occasional extra.

A dog trying swimming for the first time, regardless of breed, benefits from the confidence and safety margin a life jacket provides while it learns its own swimming ability in a controlled way. Senior dogs with reduced muscle strength or joint issues, even if they swam confidently in their younger years, may also tire faster than they used to and benefit from the extra support.

A properly fitted jacket should sit snugly without restricting the dog's normal paddling motion, and it should have a sturdy top handle, which makes lifting a tired dog out of the water considerably easier than trying to grab wet fur alone. Testing the jacket in shallow, calm water first lets a dog get used to the unfamiliar feel before heading into deeper or more challenging water.
