Chelsea is a Miniature Pinscher owned by Carmen. She can be found in walks or contests. She wears a striped ribbon. Chelsea usually fights other dogs she encounters on walks, especially Corgis. This could be because on Nintendogs + Cats, the Corgi, Max, has an owner with the same name, which is rumored to be Chelsea's owner. Point is, she may not like Corgis because there is always one in her house, or because she was replaced by one.
