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.

Really should be opening up the wall from the inside and adding a header.
Easy enough to cut the siding with a 4-1/2" right angle grinder and a diamond blade.

I am not a carpenter. Would a single 2x4 across the top be ok? I need an additional 2 inches or so. About the width of the stud.

We do not have a picture, no dimensions, so it's anyone's guess.
I would at least double it up and install jacks on the sides.

No picture came up.
Would be interesting to see how you plan on trimming this out on the outside to keep water out.

I think the picture will work now. As for water/weather-the door is under a covered patio. It has not been an issue for the smaller door. There are vinyl flaps on both sides of the opening. The opening is also 6 inches higher than the patio on the outside.

The hole/opening needs to be 8 1/4 x 13 1/2.
