getting puppy to sleep later

Question
We have a 5 1/2 month old yellow lab pup.  He does not seem to ever want to sleep!  For a few days he would sleep until 5, but he is now getting up at 4 or 4:30.  He does need to go out, but then will usually not go back to sleep.  We have tried pretty much everything, keeping him up later at night, putting him back in his crate after he goes out, picking up his water at night - but he still seems to need to go out at 4.  We take him out at 10:30 at night -so it is not like he has to hold all that long.  

The thing that for some reason worked the best was adding canned food to his dry dog food.  I don't know if that kept his stomach full or what.  

Also, do you have a good training book you would recommend.  We have worked on sit, down, stay, come and retrieving.  I also have a 5 year old lab that I took to 4 obedience classes.  I was happy with only one instructor out of the four and do not want to go that route again.  I think I have a good understanding of what it takes tto train a dog, just need a little help.

Answer
I don't know that there is a good solution to the early arising.  Make sure there is nothing like a coffee maker on a timer signaling him.  Can you move his crate to where the morning sun doesn't come in?  4 AM?  Even now with DST I wouldn't think it would be the problem.  

If he is going in soon for his rabies shot, you might have the vet check his bladder.

When you take him out a night, Make sure he runs around a bit stimulating his body.  

There are some very poor obedience class out there.  The dogs see all the
people and dogs in the household as a pack with each having their own rank in
the pack and a top dog.  Life is much easier if the 2 legged pack members
outrank the 4 legged ones.  You can learn to play the role of top dog by
reading some books or going to a good obedience class. A good obedience class
or book is about you being top dog, not about rewarding standard commands with
a treat.  Start at http://www.dogsbestfriend.com/  a good book is better than many classes.
