I think based on everyone's posts Penny is leaning more towards the hyper side of the spectrum. We have a big house and she loves to run around everywhere. I also take her on two long walks about 30-45min each time around the neighborhood. No matter how many times I walk her she still wants to run around and play when we get home. She starts to settle down around 9pm and crashes at 10pm. She just loves to wear her self out during the day and its fun to watch her run around too.
