He is Brilliant

12 weeks old today.  Wt is 18.5 lbs.

How can a dog so smart as to teach himself to play fetch, still can't control his bladder in doors.  I took Bertie outside to play after work and thought we would see how he did with a toy outside.  I threw his squeaker ball and he went and got it and brought it back to me the very first time.  I didn't have to prompt him at all.  He will even release it with a little encouragement.   We played for about 10 minutes until he decided he had had enough and carried his ball to the back door.
