Yes dogs are smart. My German Shepherd follows me everywhere now even to the bathroom. And when I come out he runs up to me to make sure im fine. He also lays his head on my belly to feel my son move :) 27 days left can't wait.
As much as I'd like to think so, my 4 year old Rottweiler has shown no difference in behavior that would suggest she senses anything unusual. *shrug*
Absolutely. Pets have heightened senses and can detect the change in hormones.
We have a pet Conure (small parrot), and she has been very attached to me through my entire pregnancy. She'll preen my hair and skin and sleep on my baby bump like it's a giant egg.
I have a 5 month old pit and she definitely knows she licks my belly everyday and sleeps on it
