Because Chorkies are a cross between two pure breeds, there is never any real guarantee of how puppies will turn out. As such, these charming little dogs come in all shapes, sizes and colours. Some dogs are long-legged and rangy, whereas others are shorter and more compact. However, as a rule of thumb most Chorkies boast having an athletic look about them, a trait that both the Yorkie and the Chihuahua boast having.
