Dogs behaviour in pregnancy

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

The last couple days our dog has started peeing in the house, he has a doggy door his been using it but still peeing inside. It’s winter here so it’s cold & rainy outside both of which he hates, his also older & can be lazy sometimes, but it’s also got be thinking could this be pregnancy related? His a smart dog you can talk to him in Italian & he understands you, he knows something’s coming, his become my little protector, his in & out of the partially started nursery. My partner isn’t treating the situation very well I’m used to having older dogs, my last dog passed at 19 so I know there will be accidents, things happen. But my partner has never had any older pets before he hasn’t been through this, he gets mad at him. I’m just looking for any advice would be appreciated.
