I am glad you are getting your puppy back. A puppy is very much like a 12 yr old child. I can see why it did not work out for them.
Many people work and own dogs. Going home on your lunch is a good idea. Reassure the puppy and give her lot's of TLC. I hope this will be a good thing and you and your husband can keep your puppy this time. Your baby needs to be in a stable home in order to feel secure.
Jeri, Did I read your post right? Biting your Kayla in order to train her? LOL, I personally could never, ever do that, no matter how misbehaved Suzi is.
