If you're feeling blue go outside and get some Vitamin D, sunshine always cheers me up! I walk Chewy 3-4 times a day, that's at least an hour of sunlight and it does wonders for me. Couple times a week we go for a hike as well. I'm more energetic during the days and I sleep better at night. Whenever I'm feeling sluggish a brisk walk outside always does the trick.
Here I am trying to tie a high pony without a mirror, how'd I do?
