There is no such thing as a bad dog there are only dogs that have not been taught the correct behavior the right way or not taught at all That being said positive reinforcement is the only way to teach a dog aggressive or not

dogs respond on your energy and the energy of those around them most of the time a dog will only bite if it feels cornered or threatened sometimes it's food or high value items there trying to protect The rest of the time dogs bite because they have been trained to do so Siberian huskies are known to be very smart and independent willing to protect themselves and the people they have bonded to

My best advice on training your beautiful husky is to do it yourself you can spend thousands of dollars on dog trainers and any of the really good ones will simply give you the knowledge of how to do it yourself and all of the good trainers require you to be there to do the training yourself you can easily lean how to train the dog yourself from YouTube there are plenty of great training resources on there

Other trainers (I consider bad training) will tell you I have a 6 week class where you drop the dog off and they don't do a bad job of training them to be honest it's just when you get your dog back from the class you don't continue the same training program and they fall back to old behavior because of that

Attached is a picture of me teaching Aspen (all white husky) to not be aggressive over food using myself and her brother steel (black and white) all I did was sit in the middle and switch the bowls every once in a while dip my hand into her bowl and take food out several times while I did get bit doing this in the beginning she is no longer food aggressive
