Puppy waking too early

Question
Hi.  This is the 3rd Golden Retriever I have owned and I've never had this problem.  Our 5month old Golden is waking between 4:30am and 5:00am every morning.  At first I could understand that he couldn't hold it so he had to go out to do his business.  Now that he's a bit older I can't understand why he still can't wait until 6am or so.  He had like a "alarm" in him that wakes him at the same time everyday!  We did make the mistake of feeding him at 5am so I'm afraid that he now attributes to getting up early to eat.  How can I break this habit? If we don't get up and let him out he just paces(he's in our bed to sleep as the crate training for nighttime didn't go so well)We've tried just letting him out and then come back to bed. He lays down for maybe 1/2hr and then is back up pacing to eat I think.  We need our sleep! Our children our at the age that they sleep in now. This is our time finally to be able to sleep in too.  He is in the crate during the day for (2) 5hr spans while we work. He does not have any accidents in the crate so I know he can hold it at least 5hrs maybe a tad bit more.  He does go to out around 10pm at night as his last time out.  Perhaps I need to still give it more time? He's still to young to make it through the night?  Should we continue to feed him at 5am after he's gone out?  Please help!
Thanks so much!

Answer
Determine what time you want to get up, and don't feed him before then in any circumstances.  Let him out to relieve himself, and then down stay him in his bed and ignore him until the the time you get up.  Don't count on him outgrowing it.  About once a week one of us have to settle our 12 year old Lab at 5:30 AM.  Eliminate anything you can such as the morning sun or a coffee pot on a timer that could be giving him a clue.  A neighbor leaving for work is harder to control.  

If you haven't started obedience training yet, do so now.  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/

Here are some other ways to reinforce your position as top dog.

''Elevation for small puppies:  Sit on the floor and gently put your hands around your pup's middle, below his front legs, and lift him up.  He is facing you.  Hold him for 15 seconds.  Repeat until he no longer struggles.  If he is past 10-12 weeks, lift his front feet off the ground, but don't pick him up.  

Cradling for small puppies:  Hold your puppy gently on his back, as you would cradle a small baby.  If he struggles, hold him firmly until he quiets for 10-15 seconds.  With larger pups, you can do this as your sit on the floor, with your pup between your legs.

Quiet lying down:  Place your pup on the floor on his side, with all 4 legs pointing away from you.  Use your hands on his neck/shoulder area and middle, to hold him in this position.  When he is quiet, praise him.  Lengthen the time that you keep him quietly in this position.  When he accepts this position well, handle his paws and muzzle, while keeping him quiet.''

The quotes mean this isn't my original work.  It is copied from my Puppy Raising Manual.  I have long used these or minor variations of them, and they are very effective.  You may want to give him a belly rub while he is on his back too.  Helps bonding.  There is a big difference between him rolling over and demanding a belly rub, and you choosing a time to roll him over and rub his belly.  The latter cements your place as pack leader.  

Days will be getting shorter.  Along with being top dog, you may be able to get the sleep you need.  No dog gets too much exercise.
