WATCH: Woodchuck Takes A Ride Across Mass. Lake On Dog's Back

Via Wally the golden retriever loves to swim. His owner, Lauren Russell, had Wally out at one of his favorite swimming holes recently, Hickory Hills Lake in Lunenburg. He went out in the water to cool off, but he didn't come back alone.

Lauren told, "He was about 100 meters out and a woodchuck I think just crawled right up on his back and he swam back to shore with him. We were flabbergasted. It was unbelievable. We couldn't believe what we were seeing."

Wally didn't seem to mind being the water taxi, "He didn't even care," said Russell. "He like took a peek back on his back and then just kept swimming."
