I have walked my dogs many times, and both of them know exactly what I mean when I say something like "stop", or "relax", but in public one day last week, my dog decided to try and take off towards something when we were on a trail, and as I was holding his leash, he would not calm down as I told him to.\n\nI knew something was wrong when he got jumpy, but I never knew what the problem was. I don't know what he wanted to go after, but it was like he didn't even hear what I was saying, but on any other occasion, this would never be a problem. Sometimes things like this happen. \n\nYou could be playing with your dog, and all of a sudden they could become really rough, and then you say stop but they keep going as if they don't know what you meant by that command. If you understand what my point is, can you tell me what goes threw their minds when they choose to not listen?
