Looking online for doggie doors & WTF sorry but WOW, it's a door with a hole in it & a flap.... How hard is it to make one, yes I googlied it & it seems not that hard.... Has anyone else made a doggie door????? I also looked into the wall mount ones, which is doable also.... Do I really need aluminum frame, can't it just be framed with wood & with flaps attached on either side.... This is a back porch instillation.... I am trying to do this with the least amount of sticker shock as possible.... So three questions: Anyone make a doggie door, info please????? Anyone make a wall mount doggie go through, info please????? Anyone know of reasonably priced doggie doors or go through???? Thanks Tracy
