My lab, Reese, loves to play with my miniature schnauzer, Cha Cha. They chase each other, play tug-a-war with the toys, and have a great time. Now that Reese is bigger though (turning one next week) he wants to play rough. I know it is just the puppy in him and Cha Cha holds her own for a while but she seems to want to hide more than usual. How do I teach him to play at her level or will she just learn to call it quits when she’s had enough?
