MSNBC.com: Teaching your dog to swim safely, 2008-Jul-8, by Mike Celizic: Some dogs have to be taught to swim, Wendy Diamond of Animal Fair magazine said, and others, like bulldogs, take to the water like submarines take to the Cross Bronx Expressway. For the former, there is hope. For the latter, there are those bright orange canine flotation devices. Among the dogs that swim naturally and gladly, she said, are water spaniels, setters, retrievers, Barbets, akitas, Kerry blue terriers, poodles and Hungarian pulis. Among those that can’t swim at all or swim only with great difficulty are basset hounds, bulldogs, dachshunds, pugs, corgis, Scottish and Boston terriers and greyhounds.
