My St.Bernard has a thing with barking at everyone who enters the store and running around like a nut. If a guy comes in here with facial hair she will bark her head off and shes also the same way with colored people too some of the time. She doesn't like delivery men either as we have deliveries made to the store and she barks from the time they enter til the time they leave then she goes and takes a nap as I guess its enough exericse for her lol. I think shes going through the phase where she is afraid of the world.
