There was another thread very similar to this that you could look at for answers! Feel free to ask any other specific questions though if you can't find your answers here:

But to answer your question, I've found in my own personal experience (I've had two huskies) that my Huskies were just as affectionate as if not more affectionate than any other breed! My huskies loved to cuddle on the couch, loved rubs and pets, never met a stranger, and were HUGE people dogs.
They can however be aggressive/deadly to other animals unless EXTENSIVELY socialized with other dogs, cats, small animals, etc.
I personally know someone with two huskies AND a german shepherd who are 100% reliable with their cat, guinea pig, rabbit, and bird.
However, my first husky killed several cats, and other small animals, and my second husky killed my hamster, and probably would've killed any cats/small animals it could've gotten a hold of. Neither were raised with or socialized with cats or other small animals.
My first husky was VERY picky about dogs she got along with, and did get in some fights. She was not socialized with other dogs. My second husky however was socialized with several different dogs of different sizes, and never was in a fight, and was good with almost all dogs (I only ever saw her aggress toward ONE other dog, but nothing serious happened).
