I even showed my cousin a pic of Chester, and I also told him that Chester reminded me of Rufus. Well they asked me what kind of dog he was, and right away I said Rat Terrier, but then they said JRT (those were the two breeds that they thought he could be) but then I measured him, and I looked to see how big JRTs are, and he is bigger than a JRT, so we are all pretty sure he is a Rat Terrier.
