Our new addition to the family

We were finally were able to bring our new baby home after many months of waiting. This is Winchester, an English Black Lab, 8 weeks old with a champion bloodline. His Grandfather was the #1 English Black Lab in the country in 2006. English's are stockier and slightly shorter than their American brothers. I can't wait to get the training going and eventually put some ducks on the table. My wife said she's going to train him to bite me in the ass every time I miss a duck. Anyone schooled in treating butt bites?
