When is it "right" to euthanize?

If a dog has a "dangerous" behavioral problem that can't be fixed the dog need to be euthanized for the safety of the people around the dog and the dog itself. I had a dog who got so aggressive we had to euthanize her. I spoke with two behaviorists who both said that euthanasia was the best thing to do. So to answer your question, I partially agree with that statement depending on the situation.
