Poukie Bear. regarding the first answer you received:
My apologies. That unkind and unhelpful response is not typical of this board. I am by no means a dog expert but we have people on here who can help make certain your fellow doesn't get overreactive....primarily by having him play/interact with dogs who won't try to fight with him and by not getting fearful and defensive yourself.
Again, I'm sorry for the appalling answer you received; it was a rude, embarrassing and intentionally unkind response.
