Newborn Baby and Husband's Spoiled Dog? Help?

You need to make your husband understand that this problem needs to be addressed as you have a baby on the way, with an undisciplined dog in the house your child is at risk, particularly as the dog has attacked before, I can't believe your husband is this stupid tbh. As with children dogs need discipline, this way they know their boundaries and are happier and more confident as a result. Someone needs to be boss in the house, otherwise the dog will do it. Your husband needs to be educated on the subject.
