You're lucky!
I have a Doberman and he will jump in the water!
The last time I took him out to the river, I found a dead sucker on the bank so I picked it up and chucked it in the water. Next thing I know my dog does the superman and leaps in to get it. Crazy!!
He also ate somebody's trout on the shoreline. An hour later he puked out 5lbs worth of the fish.
