Prepping dog for new baby

alexandra • Married 3 years. Baby girl born 01.2016. From Chicago. Teacher. Bulldog mom. Love cooking, football and Jesus.
Our two year old puppy is basically our child. He is so spoiled and needy. He cries if we aren't paying attention to him! We are so nervous to bring home a baby - he will be so jealous. Has anyone gone through this before with their first baby? Any advice??
