We have a golden retriever that loves to swim laps. When she reaches the end of the pool, she puts out her front right paw and pushers off the wall as she heads back to the other end. I think she training for the dog olympics 1500.
Also, if one of her tennis balls sinks to the bottom in the shallow end she will swim around and around looking at it, and then will stick her head all the way under trying to reach it. She won't go under after it, just reaches for it.
Ain't dogs cute?!
