Ben is a Black Lab. He is about 14 years old. He has never shown an interest in presents or wrapping paper. Suddenly this year round about DD's birthday he decided he wanted to play with the paper. No, not just play with the paper, but open the presents. Seems to have got worse by Christmas. He was sitting beside one of us trying to get the presents out of our hands!!!! We have never wrapped him up anything before (as he had never shown interest). This year we did. We wrapped up a large milk bone in paper. It was so funny to see him opening it!
