I'm not complaing about Molly.
I love her.
Some days a little more than others.
You're right about watching her, though..

This happened in a short period this morning.
Hannah had walked her and she did her business.
I had just walked her the second time and sat at the desk (or was doing dishes). My wife came out and saw the bed.
It wasn't very long that she was alone.

As far as peeing, I was always under the impression that if you didn't catch them in the act, it did no good to discipline them.

The old dog is just a little too old.
Occasionally she gets tired of Molly roughing her up and lets Molly know but, otherwise, she tries to ignore her. Even when Molly is chewing on her

I'm not a fan of shock collars but Molly heads to the road and willfully is deaf to us calling her.
The long rope may be a better tool
