Here's Duke swimming in the lake. He absolutely loved it. After a bit, he didn't even need a stick to go after, he'd jump in on his own, swim out and come back, again and again.
Retrieving his first birdy! Once he wasn't afraid of it, he loved bringing it back and forth. Took to it right away.
And here's our attempt at a swimming pool in the backyard. He splashed around a bit and then just sat in the cool water. Silly pup.
