That is a great shot! I'm glad he enjoys the water. We tried with our Pit, but she refuses. (Coby looks like a young pitbull, I apologize if he is not. )
He's got pitbull in him, but also lab, boxer, and a few more. He's got the big pitbull head though.
Our last dog, a Boxer, wouldn't go near the water, ever. Coby wasn't sure at first, but once I put him on the sun shelf, he just went crazy and started jumping around and into the pool.
I'm not sure what's he's going to do when we finally are able to get back to the beach.
