Can dogs sense pregnancy?

Jennifer • Due Sept. 14th, 2018 💕

I have a 1 year old pom/poodle mix (who’s btw always been too hyper) but all of the sudden crying a lot & wanting to be around me. He follows me EVERYWHERE & just sits besides me while I’m cooking, or doing my hair or make up.

Can dogs sense pregnancy or is this just a coincidence?
