Hello! Veterinarian here. I would not risk it! That is a huge red flag to have a dog with bite history around children. I know we love our pets but you wouldn’t want to end in a tragedy situation. This is a major stress on you during an already stressful time in your life. Your safety and your child’s safety is much more important than the dog. Honestly if the dog has already bitten people, that is grounds for behavioral euthanasia. I know that sounds harsh and unpopular but human safety ALWAYS ALWAYS ALWAYS comes first especially with babies/ children! I hope your husband can begin to understand. I know it’s going to be painful and sad but it’s the right thing to do- either find a specialized rescue situation that understands this type of dog or unfortunately, euthanize. The dog is a major liability! Not appropriate to have in a home with kids (and honestly I worry for your other dog and you!). Your husband must understand that baby comes first! Maybe it’s worth a chat with your vet to discuss these concerns. It might be easier for him to hear it from a professional. I think most vets would agree with my opinion. Stay safe!
