I don't have any personal experience with the breed, but I did just find this write up on the AKC homepage about them:
"In temperament, the Norwegian Elkhound is bold and energetic, an effective guardian yet normally friendly, with great dignity and independence of character."
Having experience in picking out a few different breeds of dog for ourselves I read that blurb on their temperment as meaning...very protective, strongwilled, and having the propenisty for not having alot of trustworthiness around strangers. I don't know what your household make up is like (children/no children, very social with it not being uncommon to have people over to the house, etc etc...but if you do get this breed of dog make sure...and I can't reiterate this enough as we had a horrible experience with a boxer because of really bad breeding...it either comes from a very trustworthy breeder, or if getting one from a rescue just make sure their temperment has been thoroughly assessed. If you're going the breeder route, make sure to get as much info as possible on mom and dad...and if possible meet them both.
We unfortunately learned first hand what "back yard breeding" can bring about in a breed that has a predisposition for "aggressive" (especially those that have guard dog type behavioral traits) behavior. We had to put our boxer down because he was way too aggressive, we even worked with a behaviorist and she and our vet were the ones that suggested putting him down once we had kids as he was starting to growl at them (he was fine with us but strangers were a completely different story...he was becoming very scary around people he didn't know). He was beyond rehab unfortunately. So just be really diligent in finding a great breeder (which may mean more $$$...but worth it in the long run), do your homework on the breed, and if you do get one get the puppy involved in positive based obedience training as soon as possible.
I've always liked the looks of the Norwegian Elkhound, and the Keeshound (they kind of remind me of the Elkhound) was one we were thinking about before we got our Samoyed which is our current dog. We love our Sammy she's pretty much the antithesis to our boxer...she's almost TOO nice
