I still don't have a pup of my own
Hopefully I'll get one this weekend, but the woman I puppy-sit for all the time always picks up her furbaby and holds her on her back like a baby then instructs the child to gently pet her tummy. Her pup LOVES this, so it's an easy way to make sure she's not going to nip or be roughhoused too much. When she's in momma's arms, it's easy to pull her away if they get too rough.
