my pet dog bite my friend.

My cats and dog were scared of any one dressed in full black. I have no idea because none of us here wears all black. But my younger brother wears nothing but that and when he comes over they all freak out and hide, LOL. So what we did with the dog, was have my brother come over and wear his black outfits but every time he comes in, he gives the dog a treat. Kind of like training him. So now whenever someone comes in wearing black, my dog is cool. The cats still freak out and hide, but I figured that's OK, the dog I was afraid, like yours, would bite someone someday so it was important we got her over that. Good luck and I am sorry about your friend, is he OK?
