Talos learned about stairs today. In an effort to expose him to as many things as possible, it's critical that he see not just one type of steps, but as many as we can find. So today, we dressed him in his service dog vest and took him to the National Institute of Standards and Technology, where my husband works. It's a fantastic place to socialize a dog: there are rolling carts, long, shiny hallways, cafeterias filled with lots of people, noise, and dropped food, and stairs. Lots of stairs.
