As already posted it is very normal...every time I go to pet Jake ( he's 5 m.) he turns his head around & wants to gently bite I just keep removing my hand...I don't want to encourage this..keep giving him something else to gnaw on...the humping is normal also...annoying but normal..I just gently remove myself....a lot of this gets better w/ time & discouragement....he's just being a pup...
