Chester the Therapy Dog

Hi,
It's me, Chester. I have done a lot since I was here last. TV,  and modeling, even on the runway.
 I do quite a lot for a big dog. Um, I also was just four last week.
  That's cray! My mom would never use that term, but I'm young enough that I can use terms like cray.
 Even if it sounds like crayfish.  Cray. Yeah. I'm a dog. A brown dog. I am a brown dog.
