doggy door in french door?

[Meadow]

I'm considering replacing my exisiting French doors (with a single light) with separate light French door so that I might install a pet door. It's going to be costly. Which is ok if its stable and looks good.

here is the website seling these:

Has anyone seen one of these? Or had one of these? I'm getting varying opinions from door companies. I really prefer NOT to install the doggy door through a wall...
