Yes, I have intentions of breeding her once she is of age if her genetic tests come back okay.
Merles are a bit controvercial right now. Though much less so than 10 years ago. From what I have read they have only been recorded as being in existance for 25 years in the chihuahua breed. Many old school breeders and handlers are not fond of the merle coloring in chihuahuas because they feel that the color must have originated from a cross breeding. However, there is no proof of this theory. When it comes to breeding a merle it is a lot like breeding a blue. You must be very careful as to not breed two of them together as your chances for genetic defects increases. ALso, with merles you should always breed them to a darker colored mate as merling can be hidden in light colors.
