If you plan to install a dog door or cat door through a wall, it's vital that the wall be properly framed out. If you have the skills to frame the wall yourself, that's fine. We think that the serious potential for damage to the wall--through leaking rainwater into the wall--or damage to yourself--through cutting into an electrical cable--is large enough that it's probably a good idea to give the job to a licensed contractor.

Whether it's you or a contractor, though, choosing a manual or electronic dog door that has a wall kit or tunnel liners available for it will greatly simplify the job.

Installing a pet door in a wall raises a few interesting points:

  • You like to install as low as possible, while keeping the top of the opening at least as high as the pet at the withers. You can't, though, cut down into the mud still that runs around your foundation. That's as low as you can go.
  • You may not like to cut into your molding. Steps or a ramp may make the pet door accessible even though raised up above the molding.
  • The same height problem probably comes up on the outside as well. A platform, steps or a ramp might be helpful there as well.
  • If you're concerned about security, here's a great way to hide your pet door!
