Dogs Detecting Pregnancy?

Emily

Do you think dogs can detect early pregnancy? I am 7 dpo, and my dog has been extra snuggly and wanting to lay on me. She is somewhat snuggly normally, but she never sleeps in bed with me. The past 2 nights I've woken up and she's been laying right beside me in bed, with her head on my pillow. Photoa of my bug below 🙂
