Just sounds like he's trying to play with you but hasn't learned that you don't make a good toy. Doesn't sound like aggression at all. Encourage him to play with toys and if he starts going for you get up and walk away from him, then ignore him for a minute. My dog was a really bad biter but was unable to get on the couch, so for a while if he went after me I'd stand on the couch until he stopped wanting to get me. Then I'd encourage him to play tug with me using a toy so he learned that when he got the urge to play with something he knew he could use a toy. Now he has the best bite inhibition ever. You just want him to learn that you fail as a chew toy, you're never any fun when he tries to get you to play.
Tucker literally drew blood from us every day and made me never want a puppy again. But oddly enough the super bad biting only lasted a few weeks, it just felt like a lifetime. You just have to be very consistent and he'll stop wanting to use you as a tug toy.
Thank you ~Dixie's Mom~ for my awesome siggy!
