We’ve had our puppy for 2 weeks now and he is 10 weeks. I’m at home with him all the time so have dedicated a lot of time to being with him, trying to toilet train him, play with him and help him settle. However I am really struggling with just how much he bites. I don’t really mean the stuff around the house but feet, toes, hands everything! He gets really manic about it and seems really aggressive, growling and yapping. He even goes for my nose, ears and neck. I’ve done the don’t react, turn away, don’t give attention etc but nothing works. I have never had a dog before and don’t know how normal this. I’m feeling a bit deflated and down about it which probably sounds ridiculous.
