This subject is alot like politics, there are alot of different takes on the subject and NO one pat answer. I have been a dog foster parent, trainer, breeder, lover for more years than I can remember and have had every kind of dog you can imagine mostly when fostering. I truly believe in the good in all dogs but am I careful and at times wary, you betcha I am. Use common sense with any breed and if you fear a breed stay the he!! away from that breed and buy a fish.... [Eek!]
