OK, my wife wants a doggie door but we don't have a door in which to place said doggie door. I have found a pet door that is "made" to go through an exterior wall. Our house is of basic exterior brick construction and although I have been in the construction biz (in the past) I had nothing to do with masonry. So the question is, can I safely put a doggie door (small dogs) size hole in the bottom of a brick wall? Additionally can it be done in a manner that will allow said hole to be fixed should we decide to sell our house in 10 years? Any insight would be greatly appreciated.
