BIG dog owner question...?

have your kids away at a friends or in their rooms or outside. have a person not living in your home bring treats or a toy he likes an let him get used to them an do this over an over again until he relaxes. if it makes you feel better put a muzzle on him. you should hav someone esle walk him until you have your baby for your safety. do this outside, on you walks have soeone meet up with you an give him goodies. i am not an expert but this should help, it may tak a while but i wouln't know any other way. good luck
