I have a siberian husky. She's a little older, but she's always been really quiet and she hasn't barked hardly ever. Within the last month, she's started this whine...a really harsh whine, like what a human would do in pain. I've told my parents, but they don't think anything of it...but it's really not like her, at all. She just whines, constantly...she won't come to me when I call her to give her attention, so I was wondering if something else could be wrong?
I was also wondering if it could be a trait of pregnancy? We had my brother's dog here for a while, a Pomeranian, and he's not fixed, so we thought she could have been pregnant a few weeks back...but she's not gaining weight, but I still think she might be.
Any help would be terrific. Thanks.

& she was in heat.
