Sophia is her name, being ruff is her game. Sophia or Phiser as we call her loves to be ruff and hard. I don't think that she feels that pain because she just keeps going. For instance, I would be sitting on the floor and I would ask her to come over and we would snuggle together... she would run curl up in a ball and jump on me. OUCH!! BUT she can be nice and sweet as seen here:

Griffin in lying down because he doesn't fell well so Phiser need to be by him. EVERYONE LOVE the GRIFFIN!!!
