Adopted dog with biting problems

Question
We adopted a Chow Chow Golden Retriever mix about a week ago. He is super sweet and very excited. However, he bites a little too much. He doesn't bite very hard, but he doesn't stop when we say no or stop. He is about 2 1/2 years old, but still acts like a puppy, which is fine, except for the constant nipping. We don't know what his previous owners were like, but we do know that he wasn't taught discipline. Also, he keeps on humping me and my boyfriend, along with blankets. If you could help us with either of these, please get back to us. Thank you very much.

It sounds like your new dog could just use some obedience classes.  My advice would be to find a good clicker trainer to work with.  Newly rescued dogs are often anxious, and need a way to feel comfortable with the way you communicate your wishes.  Clicker training is unemotional, yet tells the dog exactly when he is right, and rewards him for correct behavior.  For now, don't worry so much about the incorrect behavior.  Once you get training him, he will be less likely to take advantage of you, or be pesky, because you will have some tools with which to make him work for his privileges.  Google "NILIF" and you will see what I mean.  
If he's newly rescued, it's possible that he's also newly neutered. In that case, it will take a bit of time for the testosterone to leave his system.  If, instead of it being sexually motivated, the humping is status-related, training should lessen his desire to do it to humans, since he will perceive you in more of a leadership role.  It's also possible that it is simply a behavior that he learned to do just for pleasure (yup, dogs do) so the best course is let him have the blanket, but say no to him doing it to humans.  The best way to discourage it is probably to say nothing, make no eye contact, but immediately leave the area and if necessary, escape into the bathroom.  Once he figures out that his favorite human disappears each time he humps, he may decide to forego the humping and start doing things you do like instead.
