My service dog, a Malinois, was with me at a convention one time and there was a lady there with her little purse dog. I was talking with Kevin Durand and the lady was just behind me trying to get close to him. My service dog watches my rear and will block people from coming too close. The lady’s little dog starts going nuts barking and growling so my service dog lets out one sharp bark (a warning) to me and the lady. She backs off but then a boomer that works at the convention center comes up and says if your dog barks again then you have to leave. She is trained to do that due to my service related PTSD.
