[MyDuke]

Questions for my YTers out there....
Since the cold weather hit the NYC area, I dont get to walk Duke as much as I usually do during the other seasons. Now when I take him out, he pulls ont he leash more and barks at other pets/people more than he usually does. He is also more difficult to control once he starts barking.

I'm considering about taking him to an obidience class but is is possible for him to unlearn his friendly behaviors?
And since he knows the sit/stay/come commands, should I still enroll him in the basic basic class?

Thanks
