Francis Albert Friday!

There is one other thing that would always get Frank going "THE FLY". Frank would always chase flys. He would open his big mouth and snap his jaws like a T-Rex trying to catch flies. Whenever he would hear a fly buzzing by the sliding door he would run like mad barking and snapping the jaws. If we just whispered "Frank, the fly????" he would go nuts. Sometimes I would try to get his attention and test him with all the key words "Frank....the fish....the blimp.....sister......THE FLY????" and he would always lose it with the fly.

I know most dogs and cats chase flys. Why do you think that is? Is is the annoying buzzing? How could something so tiny seem like such a threat???
