Hello, you’re a dog trainer, I would think this guy would have been able to put 2 and 2 together and come out with something a little more than 3. Like you’d have a dog in your home that could present that kind of risk. Just like people, if you spend enough time with them, you know their personalities, their behaviors, and quirks, and what it takes to set them off. Dogs aren’t furniture. It also seems that most people with “problem dogs” usually have problems themselves.
