Do what binka_nugget said.

My friend's new doggie had the same proble as urs if not worse.

Holly would potty EVERYWHERE & destroy the house if left alone.
I told Alex about the crate thing & he used his closed off balcony as a crate. with in 3 months, there were no more accidents & she stopped destroying the house.

SO it does take time, but it does have wonderfull results. & also a crate is like a dog den aswell. When ur doggie is out of the crate, leave it opened! Ur dog will see it as a place to get away from people or a place to go if scared. If shes in the crate on her own, leave her alone.

Thats the rule we had for RB Max, when he did fit in his crate. Oh he'll get to be about 20-30 pounds. 80 pounds later
