I don't know what to tell you, it stinks that the bias is SO prevalent. But it is. A friend of mine lost her pit mix cause her step father took it to the shelter while she was at work and they euthanized the dog the SAME DAY cause it growled at a worker messing with it's food. Personally I would call the ASPCA on the owners and just say that they have neglected to properly train the dog and you feel they can't control it. It is better than someone being really hurt.
