Dog door in a glass french door?
This is possible, but its not going to be cost effective unless you can do a majority of the work yourself.  The door pictured (and any door sold in the last decade) will have two layers of insulated glass.  This means that for what you want, you'll need a custom insulated panel made to fit on top of a wooden panel containing the doggie door.

There are companies that make door-glass-replacement packages for pets such as these:

A more cost effective solution might be to use a single layer of thick glass as a replacement panel, but you would loose some insulation properties, and you'd need a wooden frame to hold it into the door (because its not as thick as the original).  Smaller pet doors are made to fit into a round hole cut into a glass door, providing a very clean install.  Larger 22" tall doors might not be an option for this method, but great for people with "cat flaps".



Last option I can think of is replacing the large panel of glass with a custom made divided-light panel made up of several small windows.  You may be able to find off-the-shelf insulated glass panels or have single pane glass cut more economically.  The doggie door would simply be framed in place of a lower glass panel.
