Bandit used to be like that, and we got him too young also. We tried the ticking alarm clock, warm water bottle, walking, playing for hours...everything! My hubby just went to bed later, kept and I had to wake up at 5 (we got him in May and I had a month left of teaching before summer and the school was over an hour away) so he'd play with me in the morning and then my hubby, and then be back in his crate around 8. By the summer he was sleeping until 6 or 7
Good luck.
