I've been told my doctors, friends, even the vet that dogs will know you're in labor even before you do. I have a two year old female Siberian Husky, I've had her since she was 4 weeks old & she's very protective. But just this past week she will not leave my side & will put her face to my belly whenever I lay down! She's definitely acting strange but who knows, at least she's keeping me warm lol. 💙🐶
