golden retriever excited peeing

Question
We have 2 goldens that are 5 years apart.  The youngest is 4 months old.  He is smart and a real joy as a puppy, except that he pees when he gets excited.  I stay at home with him most of the time.  He sleeps in a kennel and stays in it when we go out, or when he is in trouble.  He likes the kennel.  He goes out regularly to pee, and pees on "potty" command.  When we had company this holiday season, he peed on guests, my husband and myself.  Will he grow out of this?  What else can I do besides take him out regularly?

Answer
Many dogs eventually outgrow it, but you can reduce it by building the dog's confidence up.  Start with obedience training.  The key to most behavior problems is approaching things using the dog's natural instincts.  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/  As you praise the dog for following your commands, it will build its confidence.  

Play tug of war with the dog and lose.  However at the end of the game, take the rope or toy and put it up, less the dog becomes confused about who is top dog.
Ropes from the pets' store quickly turn to hazardous shreds.   Ones I made
lasted much better.   Go to a hardware or home center that sells rope by the
foot.  Buy 2' of 3/4" poly rope.   Melt the ends, and tie  knots in it.   Get
them as tight as possible, put it in a vise and pound it with a hammer.  Watch
carefully, and be ready to discard when it comes apart.

You are already using my last suggestion, a kennel to be its den.  

You may want to take him out and drain him just before you expect guests.
