Diving Spaniel

After a pub lunch with M & G we walked around the waterfront at Mount Batten where we saw this diving dog. He would jump off the wall into about 3 feet of water and then dive down to retrieve large stones from the seabed and scramble out and present them to his owner. I've seen dogs paddling in the shallows picking up underwater stones, but never diving down. Needless to say he was full of energy and thoroughly enjoying himself.
