Yeah, most the huskies I have known have been howlers as well, but then, I've never owned one, so I can't vouch for the breed traits.
As for GSDs, I HAVE had many GSDs, and I would trust them around children as well as any other dog out there, they are in no way inherently vicious dogs. And All three that I had were bred by a top schutzhund trainer, so if it was going to be in the genes it would have been there.
All dogs are a a product of their environment, and unless there is a biological imbalance of some kind going on, I don't believe any breed is wholly bad. I'd trust my son around my friend's pit bull without a second thought, and have. I wont let my son near my other friend's lhasa apso and cocker spaniel - both which have bitten me repeatedly.
That being said, I DO believe some breeds have certain traits associated with what they were bred for, and it's a given. If you don't want a noisy dog - don't get a beagle. If you don't want a dog that will try to herd your children - don't get an aussie or a border collie. If you don't want to deal with a lot of grooming, don't get a poodle.
If you want a dog that will stay in a fence, don't get a husky
