WHAT IS THE BEST WAY TO INSTALL THE DOG DOOR TO THE BEAVERTAIL BOAT BLIND?

The best way is to set up the blind and determine where you would like the dog door to go. Trace the dog door opening onto the fabric with a marker.  Have a canvas shop cut out the opening and sew the dog door on.  It may also be glued on  with Amazing Goop.  Available at most local retail stores or hdwe stores.
