I am so happy that I came across this topic. My husband and I have no children and our puppy is 3 months old. We have been so exhausted! I never grew up with pets and could never have imagined the work we would put into our dog. I heard from friends who have had children and puppies that puppies can be more work because everything happens at once. Loss of sleep, potty training, biting, discipline, crying/barking. They say atleast with babies you get to ease into it. Well we figure this might be the best way to prepare us!
