Congrats on your latest addition!!
Very likely, he's teething. You can buy a product called "Bitter Apple" at the pet store and spray it on your hands and things you don't want him to bite, like furniture, etc.
One thing I learned from puppy school: When he nips your hand while playing, you must YELP very loud in the same fashion a puppy would yelp when they are hurt. This will shock him and she'll back off. This is how they behave when they play with bros and sisters in their litter. A high pitched YELP indicates that the playing has gone a bit too far. |
