Sierra digs for moles.... and she follows there paths... so she makes what looks like maze going through the yard!!!!

But pretty soon, the ground will be frozen... and no more moles till Spring
Then... we'll start all over!

I try to catch her in the act, It's hard because I never know when she's going to find one!! But once I catch her in the act, and tell her "No Dig" she'll stop for a little bit.
I should really try poo.... I don't know why I haven't already!
