Cutting hole in exterior brick - dog door...

I would like to cut an opening in our exterior brick wall of our house for a dog door.

- House: Single story brick in Texas / slab on grade.
- Plan on installing dog door on the back wall of the garage for access to a dog run.
- Exterior is brick / mortar, built in 1978.

I've never cut through an existing brick wall before but never having done something has never stopped me before... However, I am here asking first.

Can I get by reasonably well using an angle grinder to make the straight line cuts as needed through the brick?
Obviously I could rent a large gas powered 14" diamond hand held saw. These seems like it may be overkill and I'm thinking the smaller angle grinder would not have near the extended cut line of the saw kerf from the much larger gas powered unit.

I realize that the smaller angle grinder will be a bit slower but I have plenty of time.
Any suggestions on how best to proceed?

BTW - Mods, please move if this thread is in the wrong category.

How thick is the "brick" portion? Is it a solid 8" brick/block wall or is it a 4" (3 5/8" actual or less) with a wood stud backup? - That could change the type of equipment and saw blade that works for the opening the size that you need.
