Dorothy and me have a toy called 'yellow.' It's kind of a kong toy, but the name kong was already given to another toy so mommy and I decided yellow would be a good name for it. What makes yellow special is that when ever mommy says 'Baxter, go get yellow' I know that means it's time for peanut butter! Once I grab it and give it to her, she takes yellow and the other kong into the kitchen, fills them both with peanut butter and then hands them to me and Dorothy.
Although I really like fetching yellow for mommy - that's only because I know what it means. I still prefer to eat my peanut butter out of the proper kong so Dorothy always ends up with yellow in the end.
