Anyone else’s pet misbehaving since you got pregnant?!

According to google this is totally a thing because they can sense the changes happening. We rescued a dog two years ago and have had zero problems with peeing in the house and all of the sudden he is marking all over the place. 😩 It started a couple weeks ago with a few tiny spots but today while I was gone for a few hours I came home to a dozen or so tiny little pee spots on the carpet. We’ve never crate trained him because he has baseline anxiety (he’s on meds) and he just never really needed the crate. It’s not a full blown puddle/accident and he’s given tons of opportunity to go outside. I plan on taking him to the vet to make sure there’s nothing going on but he seems totally normal other than the marking. I honestly wonder if he knows he’s getting a little human and is marking his territory before he gets here?! 🤯
