My Sergeant is a year old on Halloween. He has always play bitten and we tell him no. He started biting my daughter who I have to admit never put him down, so we corrected her but he is still a bit aggressive towards her.
I am the Alpha dog and he has never bitten me, until this Sunday. It started early in the day when he ran up to my sons
friend and showed his teeth and growled. I talked to my trainer who recommended a muzzle when he shows aggression. We did this and then later I let him run about the house, where he eventually settled on my
bed with me. I moved my foot and he went for it, I moved again and he attacked. When I went towards him to tell him NO, he bit me. I have a mark and a bruise on my breast where he got me.
this morning he got loose and ran to the street and started showing teeth and growling at a passer by...the woman was pretty scared.
I am not sure what to do and my family is very frustrated. Any Suggestions??????
