I think Luna has a case of cabin fever. She was antsy all day and kept asking to go outside. It was freezing outside, but she was happy to go for a walk even without a coat. Mike and I, on the other hand, were not interested in anything but a quick potty break. I was feeling under the weather and just wanted a day of rest.
I'm sure what she needs is a good run to wear herself out, but that is not in the cards right now. I think I will need to take her to my parents' house to give her a change of environment. We might be able to wear her out with some obedience exercises. Until then, I'm looking forward to her next physical therapy session.
