Trixie (pug) is one of our overnight hotel guests and has been with us for about 5 nights. The one thing I will never understand is how some dogs always have LOTS of energy! She plays hard everyday, and then wakes up the next day and has the same amount of energy. This means that she is sleeping great in the hotel! If I was going to the gym for the past 5 days for 9 hours each day eventually I would get tired the next morning. Not Trixie. I know when she goes home she will be tired and sleep for a few days. We call this the "Pampered Pooch Playground hangover".
