It's okay if you don't know what I'm talking about. For a long time, this show's existence was a mystery in my home. My younger siblings adamantly denied having watched it when we were small, and repeatedly asked if I wasn't making it up. Might I have just imagined substantial parts of a memory too old to clearly remember? My mother gave evidence for my side, though she didn't remember the show's name, so all I had to go on was my recollections of a puppet dog who drew other dogs who solved mysteries and of Jim Henson's name on the title card.
It wasn't until one day in second year that I stumbled across the Dog City page of the Muppets Wiki. I immediately did the long-distance equivalent of bursting into my sister's room and shouting, "I didn't make it up! I didn't make it up!" It's also a really good show, so that's another reason I'm glad I found it again.
