Anyone have a dog door? I am curious to see if you like it because I am thinking of doing one. It would be the outside, heavy duty version with security panel. We really only need it for when were on vacation and we dont want someone to have to come over several times a day. My concerns is with resale when theres a huge hole in the siding, I can patch everything else fairly easily but the aluminum siding would be a pain. It is painted so I coud match it colorwise, but just replacing the piece would be a pain. We have a large dog so its not a tiny hole.
