Hi Mad, thanks for that.

So for now, I must be
ever vigilent and watch her every move and stop her from digging and either
give her her own place to dig to her hearts desire or just stop her
altogether. I fear as smart as she is I will have to designate her a spot
as her own to dig. The first clue of this impending disaster was when I
first had her and as I was planting a new pot of perennials and plants, she
jumped up and started digging with me in the pot of dirt. I should have
never thought it was cute...................little did I know....

I wouldn't recommend giving Sugar her own place for digging in soil,
because she won't remember how far her patch extends. Our dog has an old
baby bath out in the garden; she likes digging water :-)

Janet.
