So I have a bitey puppy when he gets the zoomies and I understand this is completely normal puppy behaviour. we are working on it by redirecting him to toys and getting him to use a gentle mouth. but I get really frustrated when strangers or family friend come to him and get him fired up and then get mad when he nips and then they try to give him a swat or hold his mouth shut to which he always responds by escalating his biting. He seems to make great progress with our techniques and then takes a step backward when they do this. I try to explain that that doesn't work for our dog and that's not how we are training him but they seem to think its no big deal, Anyone else have this issue with friends? How did you address it? Besides holding their mouth shut
