ANSWER: Well what usually works really well with dogs like this is to coax them with a small treat and give him lots of praise when he does something on his own-that usually gives them more confidence and over time he will come out of his shell

QUESTION: what if he wont take treats out side as he wont also he has  a habit of grabbing my arm with his mouth and holding hard to take me some were where he wants to go i think its his bed he trying to get me to go to is this normal as each time seems a bit harder but im sure its not to hurt me

Answer
When he bites at you yell "out" and pretend it hurts you,even if it doesn't,because they usually don't want to hurt you,once they realize that they have(or think they have) they will stop

If he won't take treats to go outside,just try to really coax him with praise and when he does what you want give him lots of praise
