The last two days when I've come home from work, Trevor has been "out" too. But I think one of the other dogs has knocked over the date trying to get to his food and treats I leave him with when I'm gone. I've put him in there for short periods of time and he's never escaped.
But we have a huge back yard and since the weather has been nice I leave the back door open so the other dogs can come and go during the day and I think that's what he's been doing. He LOVES outside and he never gets tired of playing with my female rat terrier. She is such a good baby sitter and loves running through the yard and keeping him entertained. It's good for her and him
When Trevor was having to stay locked in the backroom while I was at work, he would be just frantic when I would come home... screaming and holding on to my pant leg when I put him down. Since he's been loose, he just comes running to the front door with everyone else glad I'm home ready to eat

So I guess I'm going to have to put a doggie door in because before too long it will be way too hot to leave the house open and then he'll really be mad

that he can't run and play.
He hasn't had any accidents in the house or torn up anything since he's been loose, so hopefully it will work out.
