I installed a small dog door a couple of years ago. I installed it as close as I could to the back door. It ended up being between the door frame and a stud that is 5 1/2 inches away. The small dog door fit perfectly between the 2. Now we have a bigger dog, I bought the next bigger door, but to install it in the same location I will have to cut the stud that is 5 1/2 inches from the door frame. What is best option here? I think framing the new dog door would be easier than trying to replace the Hardy Board that I cut for the original door.
