My life changed when we got a doggy door for our little jack. It was a god send. Now I went and got a big dog... no... HUGE dog and can't stand the idea of not having a doggy door. But I don't trust the big doors in terms of security against break-ins. Any suggestions? We are doing construction on a new house so I can have them rig up something custom made, but I haven't had any ideas yet aside from those collar triggered doors which I don't really trust. I think a good kick is all you need to get those doors open. Any brilliant ideas? Or do I have to give up my saturday morning sleep-ins to let the dog out?
