If she is anything like my lot she'll be enjoying the peace and quiet while you are out. we got our seond dog as we thought the original was lonely and bored while we are out, it made no difference they both sleep most of the time we are out, with the odd play fight. As long as they get plenty of attention and love the rest of the time most dogs do well alone and if anything are happy to see us gone so they can rest and relax in peace.
