Talk with a dog lover and you’ll likely hear about how amazing their pet is. Talk with a pregnant dog lover and you may hear stories about their dog being more protective, loving, or otherwise showing that they know their human is pregnant. Maybe this even describes your situation. There’s no doubt that dogs are super observant to the world around them — perhaps even more observant than people realize. So if you have an acutely observant dog, you may wonder if they can sense when you’re pregnant. Medically speaking, dogs can certainly detect some pretty remarkable things.
