Personally.. If I really wanted protection training... no. Only because of how much that takes, especially if you have a full time job and you're a mom. That or I would stick with OB with your current one and get the puppy if that's what you want.. from experience though... I would not get a puppy again just because the opportunity presented itself. It wasn't a mistake but I was so incredibly stressed..
