I bet you're wondering WHAT a duh ta duh is. lol Well here's the story. When our other little dog, Chip was young we started giving him the cardboard roll out of the paper towels. When we would blow through it like you do and make the noise, he would go crazy and jump at your face trying to get it. One day he jumped at it and rammed the thing back into my face and man I thought there for a minute he had busted my lip.
Anyway it just so happened that our daughter was baby sitting this little boy named Colby that was just a few years old and he called the cardboard center a duh ta duh. So it stuck and that's been it's name ever since. So anyway tonight I was wrapping presents and emptied a roll and just had to give the roll to Buddy. You should have seen him playing with that roll. He didn't do like Chip to begin with on it but he soon learned he did like the thing. That is once hubby cut it in half so he could manage it. It was wayyyyyy too long. He drug that thing all over the living room and kitchen playing with it. It was so cute. I just had to get some pix of him with his first experience with a duh ta duh. ;)
