My dog can smell my breastmilk and she tried to bite me! 😂

I have a 1.5 year old, 8 lbs toy poodle. She has been super clingy since we found out I was pregnant. She sometimes smells my belly and licks my belly. But today she was laying down next to me and she was digging around for something, my breast! 😂 next thing I know, she bit my nipple! It didn’t hurt cus she’s so little, but it was weird! Then she shifted to the other nipple and tried to lick it (over my shirt of course)

Are dogs able to smell the breastmilk this early in pregnancy? I’m only 22 weeks.

Has this happened to anyone??
