Tag is a Terrier, he can't help it —he was born that way.
To his credit he is kind of wimpy for a terrier and that is a "Good Thing".
Training a Terrier is a new experience for Freda, but she is getting a feel for it
and Tag is coming around to her way of thinking.
He also discovered that not only is there a ball in the box,
sometimes there are balls on the ground on the way back from the box.
If you get a treat bringing one ball back,
you might get more if you bring back two, and two fit nicely in his mouth.
I'm not sure if it's about the treats or the extra balls, but he didn't miss his chance to make me laugh.
