I just need help with knowing if I can use a fear of huskies as an example because I never feared them, and then one day one killed my dog and from there I was always scared of them?

Answer:
You could use that yes.
Explanation:
If something you used to not be afraid of all of a sudden hurts someone or something you love then of course your going to be afraid of them. I'm terrified of spiders but for a different reason, fear can be stimulated from any source.
