We got together today with some friends from our Lab board, we went to Union Reservoir in Longmont, CO. Phyfe, (1/2 Mastiff 1/2 Saint) was not interested in swimming. He kept barking at Earnest (1/2 Dane 1/2 Lab) like he was saying "DUDE, that's cold WATER, not snow, WATER!"
He doesn't understand retrieving either, he looked kind of wistful, like "I want to have fun, too, but I don't understand these games." He did have a great time, though. Earnest has his Lab mommy's love of water, and he'll play fetch as long as you'll throw something. All in all they both had a blast.
