Girls, I have a question: do you have dogs of large breeds at home, how did they react to the baby's arrival? Because my Rottweiler girl is four years old, my husband raised her so that she understands the owner by half-words. But we don't have children yet, and soon a baby will be born, and it's unknown how she will react. Maybe she won't let anyone else near us. In general, I don't know. Can you tell me if anyone has encountered this?
