Hi everyone!

A couple months ago we adopted an amazing, nearly 2 year old Husky from owners that were giving this beautiful boy up. We got him largely for our 15 year old, who has been lonely and struggled making friends after moving to a new town and country.

While the dog is generally great - he may be the most well behaving Husky of the 3 I've had in my life - we have had an odd behavior issue when it comes to our son.

Whenever our son goes near him, even just to pet him, he starts to growl. If we are in the room with him, he will immediately run towards closest bone or toy and protects it. He no longer walks him either because he jumps all over him and does not behave on walks with him only.

It's very frutrating as we got the dog for our son, and they have this relationship that worries us that it could develop into actual aggression in the future.

Any suggestions greatly appreciated!

The way I'm going to phrase this is going to come out all wrong, let's see of we can work with it.
You say "we got the dog for our son" but don't indicate, that I can see, whether this is something your son wanted or not.  
Parents are weird!  They try to solve a problem that isn't there because they see a problem ... without ever making sure there is one. Since I moved around a lot as a kid, I can understand being lonely and struggling to make friends ... there is a problem there, but is a dog the solution? Doesn't that just isolate him further? If you're church goers, is there a youth group for his age; how about after school activities - chess club, drama, sports, etc?

If the boy does really want to engage with the dog ( not just that you want him to engage with the dog ) then the best thing I can suggest is for you to get out of the immediate picture and for him to just back off and let the dog come to him.  You're, in my opinion, looking at the old comedy of momma being a matchmaker to two kids who don't like each other ... give them a chance and they may grow to, push them and it's a guarantee that you're going to push them apart.

What I'd do is give your son a pocketful of good, smelly treats. When he comes into the room where the dog is drop a treat and go on about his business.  Object, if your son has these good treats that the dog can smell then eventually the dog will recognize that he's the bearer of good things and start reacting to him in a good way.

If your son doesn't want the dog then either accept that you're going to have a third or find him a new good home (not advised lightly.)

As Al said, you gotta be real about if your son actually wanted a dog and has the mentality for caring for a dog. Especially one like a husky that tends to be a very assertive high-energy personality that will take advantage of people who are nervous or naive.

If your son is interested in having a dog then what is your son's responsibilities with the dog? The act of feeding a dog is one of bonding. Yee who holds the food holds the power. I am responsible for the upkeep and needs of all three of my dogs. While my husband will pet them and occasionally let them out to pee he doesn't feed them or walk them or generally take them places. Because he is a side character in their life quest essentially they do not listen to him nor respect him like they do me and he struggles to manage them on his own. He needs responsibilities with this dog and to have the dog earn everything he wants from him. In return the dog will better respect him and they will find an easier time.

Even if the dog is great with you and well trained having your son take a training class with the dog can be helpful too. In many cases the owner needs trained as much if not more than the dog.
