We have besides my furbaby Gigi, a rescue that is eight years old and weighs about 60 lbs.   Guess what, he is terrified of any bug.   All he has to do is see the fly swatter and he runs for the bathroom.  We can tell when a fly gets into the house because he takes off.  He has always been like that, he does not like to be outside because of the flies and other bugs.    Lucky for us Gigi has not followed in Buster's footsteps.
