Hillman video pup?

How old is the pup when he begins in the pup video?I may have missed it with my lil girl running back and forth.

The pup is 11 weeks and when it ends I believe he's at 22 weeks old.

If Im not mistaken at one time in the video, Bill mentions that Nick is 12 weeks old.

Not positive going on memory, but I do believe begining and end age are given in the credits at the end of video.

Thanks guys.
