Is this what "dog tired" feels like?

Today began with another city training session. Not to toot my own horn, but I am getting pretty good at this stuff... Mom had to be in laboratories all day, learning new ways to treat wounds, like the ones I had. She was afraid I would be lonely, so at lunch she brought me to a dog play center, where I spent the rest of the day with a pack of dogs my size. I got to take cookies home, and they said I am welcome to come back tomorrow. We'll see. Tonight I am so tired that I barely got up to meet our friends Danielle and Becca who have also come for the conference. I must be dog tired...
