Can I have a husky without joining the vampire hunters in Dawnstar? Are the husky immortal?

How often dragons and vampire attacks in towns? I haven’t do the quest in Whiterun where you need to talk to the yarl about the dragon. So I’m safe from the dragon attacks and my character is not yet prepared.

Can you survive skyrim without maximizing smithing, alchemy and enchantment?
No clue, sorry.
It looks like dragons tend to spawn more often after fast traveling. For vampires, it looks like frequency of attacks escalates as time goes on: https://steamcommunity.com/app/489830/discussions/0/1648791520840376016/
It’s definitely possible to survive without these, but survival is easier with them. I recommend playing the game for a few dozen hours, then go to Whiterun and use all of your stores-up materials to binge on smithing. Alchemy and Enchanting didn’t matter as much to me as Smithing did.
Enjoy having fun with a great game!
