My 1 year old husky mix was neutered a week and half ago.  I got some feedback yesterday about his potty regression. But the last two days he has actually displayed aggression. Paché was never aggressive. Playful and energetic yes. But he randomly launched to nip my mouth when I was petting him, tried to put his teeth on me when I was adjusting him cone, and tried putting his teeth on my husband because his lead came off and he was trying to put it back on.

I am worried. We have an infant. An aggressive dog is not an option in our home, but we love Paché and really would never want him to not be in our home. Help!!

The cone can make some dogs nervous because it can restrict their sight, but a lot of times it's the attempt at restricting exercise that makes them antsy. Huskies just have so much energy and if they can't get it out they can express that energy in many different ways. Keep a routine, work on mental stimulation to assist in keeping his energy burnt off. Once he can go back to full exercise much will likely pass. His hormones can take around a month or so to even out and that bouncing around can make him a little funny until it settles.

I didn't reply at first because I don't like cones and have been successful in not having to use them.  But I'll go along with Jenn ,,,
I can easily picture a cone making some dogs nervous / uncomfortable.  The few times I've needed one I've used the ones that look like a childs swimming pool toy ( a circular inflatable in the pool )

Something like this might be less intrusive. Remember, he can't see things like he normally would. If he's nervous about not being able to see what you're doing, that would easily explain two of the three incidents you describe.
