What is the difference between a regular Yorkshire terrier and a chocolate Yorkshire terrier?

The primary difference between a regular Yorkshire Terrier and a chocolate Yorkshire Terrier lies in their coat color. A regular Yorkshire Terrier typically has a blue and gold coat, while a chocolate Yorkshire Terrier exhibits a rich, chocolate-brown coloration with tan or gold markings. This color variation is due to a genetic difference, with the chocolate Yorkshire Terrier resulting from a recessive gene. Aside from color, both types share the same breed characteristics and temperament.
