I'm having a problem with finding a dog door to find my needs. I have a smaller than usual sliding glass door (I think approx. 6'x6') and I've seen all kinds of dog doors that fit as inserts in your sliding glass door. But I don't want those kind because it would only leave a tiny, barely useable space for us humans to walk through. We just bought a brand new house and I would rather not cut through walls. Does anyone know of any other alternatives, specifically if I could find a doggie door that would install in the stationary glass section of my sliding door? Or could this section be cut to fit a dog door? Any help is appreciated!
