New Dog Swimming Study Surprises Canine Community
Chances are you learned to swim using the “dog paddle” stroke. Chances are you’ve also observed your dog “paddling” in a pool, lake, ocean, or bathtub. Newswise.com reports that new research from The Society for Integrative & Comparative Biology indicates we humans may have it all wrong when it comes to understanding the swimming technique of dogs. According to the latest tests, dogs aren’t “paddling;” they’re trotting underwater.
Dog paddling is running underwater
The term “dog paddle” has been applied to the way humans, turtles, even armadillos swim but has never been studied in dogs before now. Dr. Frank Fish, a biology professor at West Chester University in Pennsylvania, set out to answer the question of how dogs paddle. The answer was surprising.
Before you roll your eyes and hit the “back” button, know that Dr. Fish was searching for an answer to a bigger question. The appropriately named Fish was actually trying to understand how mammals (such as whales) evolved from walking animals to swimming animals. Fish postulated that if he could understand how land mammals — such as dogs — swim, he could hypothesize how whales went from paws to fins. That and he wanted an excuse to film his own dog swimming in a water tank. His family Christmas cards must be stellar.
Fish and his fellow researchers used eight different dogs from six breeds. They evaluated tiny pooches such as the Yorkshire terrier and large dogs like the giant Newfoundland. Fish quickly discovered they needed a bigger tank if they were going to use the Newfie. Me? I would’ve downsized to a Great Dane. Fish (I love writing his name) eventually commandeered a horse rehab pool from the University of Pennsylvania. Good thing they didn’t lose the Yorkie in there.
This was a pretty straightforward experiment. The dogs were given the opportunity to swim in the pool and filmed, you know, dog paddling. Only there weren’t, you know, dog paddling. When Fish and his colleagues reviewed their experiment, they discovered – wait for it – the dogs looked like they were running underwater!
Despite your giggles, this was serious science. Fish observed that his swimming dogs displayed a gait similar to a terrestrial trot. He also found that the “dog paddle” is actually a trot with a twist (my words). The “twist” is that the legs move beyond the normal range of motion of actual
