I don't know if this will help or is appropriate for you but the ONLY thing that stopped my two dogs after 3 years of fence breaking (and the constant raising of fence heights) was putting in a doggy door so they had access to the house while I was gone.
Thanks Sammy, the problem is she is doing it even when we are home, I know she is lonely but it is difficult with a little one and with this ridiculous weather to get outside with her.
