SANTEE, CA—Family dog Loki experienced the best day of his life for the 400th straight day Monday, the black Labrador retriever reported. "I got to go outside! I got to sniff the bush!" Loki said, wagging excitedly. "I saw a squirrel and I barked at it and it ran up the tree! Then I came back inside, and the smoky-smelling tall man let me have a little piece of bacon and then I drank from the toilet!" Loki will experience the best day of his life once again tomorrow, when he digs a hole, chews on a slipper, and almost catches his tail.
