Hello, and thank you for your question. Puppies are teething around the ages of 3-6 months, which makes them interested in biting anything and everything at times! Ensure that he has appropriate, safe toys for him to chew on, such as rubber Kongs filled with treats or peanut butter, and rope toys. You can also try putting these toys in the freezer, which some puppies like as it helps soothe their irritated gums. When Shadow tries to bite you, give a firm "ow" or "no". Never hit him or use any other form of physical punishment. Instead, offer him his chew toy to play with on his own. Walk away, cross your arms and legs and do not give him any further attention. If this does not work, you may need to find a toy that is more rewarding for him, such as putting something even more tasty into the toy. The good news is that teething will finish by 6 months, so this should be a temporary behaviour. However, we want to teach Shadow what is appropriate to chew on, and what is not. Here is an article with some further tips to help prevent destructive chewing: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=3701 I hope this helps!
