NEED ADVICE ON 5 MO. OLD PUP'S BEHAVIOR

Ok no offense intended.  Your dog is acting fearful (which at this age is not necessarily unusual).  You provide attention and comfort.  Dog learns be fearful, lots of attention.  Get the idea.

Start paying attention to being NOT fearful.  Teach some tricks to use when he is being fearful.  Do the trick, it redirects attention and provides the attention for the trick behavior. 

Start taking the dog one new place per week.  It is perfectly ok not to do anything there, just stand around and let the puppy adjust.  Keep returning (try for 5 days out of 7).  Each day  should go smoother and easier.

Start a training class now even if you have to go with a private option for a short time.  Look for a trainer off the APDT website.

Yes take your puppy to obdience class and socialize, socialize, socialize.  Socialization is the most important part of raising a puppy and espeically a pup who is showing some anxiety.   IMHO implement the NILIF program to raise a good confident and obdient dog.
 The NILIF program is remarkable because it's effective for such a wide variety of problems. A shy, timid dog becomes more relaxed knowing that he has nothing to worry about; the owner is in charge of all things. A dog that's pushing too hard to become "top dog" learns that the position is not available and that its life is far more enjoyable without the title.

It is equally successful with dogs that fall anywhere between those two extremes. The program is not difficult to put into effect and it's not time consuming if the dog already knows a few basic obedience commands. I've never seen this technique fail to bring about a positive change in behaviour; however, the change can be more profound in some dogs than others. Most owners use this program in conjunction with other behaviour modification techniques such as coping with fear or treatment for aggression. It is a perfectly suitable technique for the dog with no major behaviour problems that just needs some fine tuning.

ATTENTION ON DEMAND
The program begins by eliminating attention on demand. When your dog comes to you and nudges your hand, saying "pet me! pet me!" ignore him. Don't tell him "no", don't push him away. Simply pretend you don't notice him. This has worked for him before, so don't be surprised if he tries harder to get your attention. When he figures out that this no longer works, he'll stop. In a pack situation, the top ranking dogs can demand attention from the lower ranking ones, not the other way around. When you give your dog attention on demand you're telling him that he has more status in the pack than you do. Timid dogs become stressed by having this power and may become clingy. They're never sure when you'll be in charge so they can't relax. What if something scary happens, like a stranger coming in the house? Who will handle that? The timid dog that is demanding of attention can be on edge a lot of the time because he has more responsibility than he can handle.

Some dogs see their ability to demand attention as confirmation that they are the "alpha", then become difficult to handle when told to "sit" or "down" or some other demand is placed on them. It is not their leadership status that stresses them out, it's the lack of consistency. They may or may not actually be alpha material, but having no one in the pack that is clearly the leader is a bigger problem than having the dog assume that role full time. Dogs are happiest when the pack order is stable. Tension is created by a constant fluctuation of pack leadership.

EXTINCTION BURSTS
your dog already knows that it can demand your attention and knows what works to get that to happen. As of today, it no longer works, but your dog doesn't know that yet. We all try harder at something we know works when it stops working. If I gave you money every time you clapped your hands together, you'd clap a lot. But, if I suddenly stopped handing you money, even though you were still clapping, you'd clap more and clap louder. You might even get closer to me to make sure I was noticing that you were clapping. You might even shout at me "Hey! I'm clapping like crazy over here, where's the money?” If I didn't respond at all, in any way, you'd stop. It wasn't working anymore. That last try -- that loud, frequent clapping is an extinction burst. If, however, during that extinction burst, I gave you more money you'd be right back in it. It would take a lot longer to get you to stop clapping because you just learned that if you try hard enough, it will work.

When your dog learns that the behaviours that used to get your attention don't work any more its going to try harder and it#%92s going to have an extinction burst. If you give him attention during that time you will have to work that much harder to get him turned around again. Telling him "no" or pushing him away is not the kind of attention he's after, but its still attention. Completely ignoring him will work faster and better.

YOU HAVE THE POWER
As you are his owner you have control of all things that are wonderful in his life. This is the backbone of the NILIF program. You control all of the resources, playing, attention, food, walks, going in and out of the door, going for a ride in the car, going to the park, anything and everything that your dog wants comes from you. If he's been getting most of these things for free there is no real reason for him to respect your leadership or your ownership of these things. Again, a timid dog is going to be stressed by this situation, a pushy dog is going to be difficult to handle. Both of them would prefer to have you in charge.

To implement the NILIF program you simply have to have your dog earn his use of your resources. He's hungry? No problem, he simply has to sit before his bowl is put down. He wants to play fetch? Great! He has to "down" before you throw the ball. Want to go for a walk or a ride? He has to sit to get his lead snapped on and has to sit (2)
while the front door is opened. He has to sit and wait while the car door is opened and listen for the word (I use "good") that means "get into the car". When you return he has to wait for the word that means "get out of the car" even if the door is wide open. Don't be too hard on the dog. It#%92s already learned that it can make all of these decisions on its own. It has a strong history of being in control of when it gets these resources. Enforce the new rules, but keep in mind that your dogs only doing what it#%92s been taught to do and its going to need some time to get the hang of it all.

You're going to have to pay attention to things that you probably haven't noticed before. If you feed your dog from your plate do you just toss it a treat? No more. He has to earn it. You don't have to use standard obedience commands, any kind of action will do. If your dog knows "shake" or "spin around" or "speak" use those commands. Does your dog sleep on your bed? Teach him that he has to wait for you to say "good" to get on the bed and he has to get down when you say "off". Teach him to go to his bed, or other designated spot, on command. When he goes to his spot and lays down tell him "stay" and then release him with a treat reward. Having a particular spot where he stays is very helpful for when you have guests or otherwise need him out of the way for a while. It also teaches him that free run of the house is a resource that you control. There are probably many things that your dog sees as valuable resources that hasn#%92t been mentioned here.

 The NILIF program should not be a long, drawn out process. All you need to do is enforce a simple command before allowing him access to what he wants. Dinner, for example, should be a two or three second encounter that consists of nothing more than saying "sit", then "good", then putting the bowl down and walking away.

ATTENTION AND PLAY
Now that your dog is no longer calling the shots you will have to make an extra effort to provide him with attention and play time. Call him to you, have him "sit" and then lavish him with as much attention as you want. Have him go get his favorite toy and play as long as you both have the energy. The difference is that now you will be the one initiating the attention and beginning the play time. He's going to depend on you now, a lot more than before, to see that he gets what he needs. What he needs most is quality time with you. This would be a good time to enroll in a group obedience class. If his basic obedience is top notch, see about joining an agility class or fly ball team.
NILIF DOES *NOT* MEAN THAT YOU HAVE TO RESTRICT THE AMOUNT OF ATTENTION YOU GIVE TO YOUR DOG. The NILIF concept is about who initiates the attention (you!), not the amount of attention. Go ahead and call your dog to you 100 times a day for hugs and a fuss! You can demand his attention; he can no longer demand yours!  

Within a day or two your dog will see you in a whole new light and will be eager to learn more. Use this time to teach new things, such as 'roll over' or learn the specific names of different toys.

If you have a shy dog, you'll see a more relaxed dog. There is no longer any reason to worry about much of anything. He now has complete faith in you as his protector and guide. If you have a pushy dog he'll be glad that the fight for leadership is over and his new role is that of devoted and adored pet.

It sounds as though this puppy was not properly socialized as a young one.  Do yourself a huge favor and stop coddling fear.  Act the way a leader would - nonchalant and unafraid.  Grab a copy of "Help for Your Shy Dog" and "The Cautious Canine" (dogwise.com or amazon should have them).  Remember that your little guy may need a bit of time to get used to you, but still start your training asap with a good trainer who uses positive reinforcement techniques.  The last thing a pup like this needs is force training that will make him even more afraid.  Reward bravery!!!!!  And, since he is a Husky - they have a hard time with "come when called" - do not call him until you get this DVD - "Really Reliable Recall" by Leslie Nelson.  You won't be sorry)

I believe it is quite normal for husky pups to be "skittish". Ignore the fear and just be matter-of-fact. Show him through example that it's nothing to be afraid OF. I'd avoid physically forcing him to do anything, and knock off the "soothing talk" and "showing love". Any act of bravery should be cheered and rewarded.

I agree that socialization will go a LONG way to help your puppy gain confidence. 
 
Another thing that helps is just plain time.  A puppy is compltely overwhelmed with new experiences.  Can you imagine how hard it would be to be taken from your mom and siblings and start your short life all over with people you don't know and don't speak your "language."  Dogs understand body language more than speech, regardless of what people will tell you.  They do respond to commands, but that's just repetition.
 
Some things that help puppies gain confidence:
 
-Keeping YOUR body language calm and confident
-Sticking to a redictable schedule every day
-Meeting other friendly dogs
-Taking your dog to places where a lot of stuff is going on (down the main drag of town on a Saturday, etc.)
-Not coddling or sweet talking when he's scared
 
The day that you see your puppy approach something or someone he was previously terrified of will be the day you'll want to lavish him with praise.  That day will also be incredibly rewarding for you, personally, because you'll know that it was because of all your love and care that he managed to build that confidence.
