Ive had this 2 year old dog a week and a half. I took her to the dog park for the first time where I discovered she can climb trees! We had been there fo 2 hours. She had exhausted herself (we thought) chasing squirrels. She was laying under a bench, panting one second, gone the next. I happened to have my camera around my neck that day, so when she took off, I followed her and snapped 3 photos, this being the last. She is 4 now and is still squirrel crazy and makes me laugh every day!
