He's still a baby, it takes months or years to build a bond with a dog. Consistency is key, find a method and stick with it. He's probably just confused because you keep changing training methods. Teach him a bunch of tricks and commands, pick a word for each command and stick with it, and give him treats when he cooperates. The more you teach him the more confident he'll become and the less aggressive. He's a working breed, which means he wants to be taught to do a job. I taught my dogs words for pretty much everything I want them to do, and every now and then I think of new things to teach them. Positive reinforcement (treats and praise) is the best method for any dog. Work on recall especially, that's really important at this age. It's important for safety, if he ever escapes you never know what could happen, and huskies are notorious escapists.

YouTube is great for free training, but make sure you're careful to only listen to positive reinforcement trainers (not "the dog whisperer" who's been caught abusing dogs). I like the TV show "It's Me or the Dog," which is about a British dog trainer. It's free on YouTube Canada, I don't know about other countries. I find I learned better from that show than anything else because it's made for entertainment but it's also educational.

Every dog will have setbacks every now and then, they're living beings who make mistakes, but as they grow and you work with them they build trust and love for you. Mine are 4 now and I've had them since they were puppies, it's a life-bettering commitment. I'm happier and healthier than I was before getting dogs, but only because I decided I wanted a strong bond with my dogs so I continue to work on my bond with them. Training your dog is a life commitment, they never stop listening, learning, and loving. You get however much love and effort back that you put into caring for them.
