Does anyone have a dog? I am pregnant and we have a Yorkie-Bichon mix. He will be almost 2 when our baby will be born. But ever since we got him, he hasn’t been good with kids. Specifically toddlers. He gets riled up and barks. He’s never bit anyone. It just seems like he wants to play with them but we hold him back because they’re little. And holding him back makes him go crazier. I also think he just doesn’t know what to do with toddlers. We hold him back because we don’t know what he will do. We love him though. He’s a really sweet pup. Just hoping he’ll warm up to our baby.
