Customer Question

i want to breed my sheltie. i have a male and female tricolor, a male and female blue merle, and a male and female white merle. and i want blue merles. is it possible for me to have blue merles that breed true?
if i want as many blue merles as possible, which two dogs should i breed and why?

You want to use caution when breeding merles. Never breed a
merle and a merle together. This a good website on merle
genetics
http://bowlingsite.mcf.com/Genetics/Merle.html

The most important piece of info off that webiste:

On average over a large number of litters, breeding merle to
merle will produce one fourth full colored dogs, one half merles
and one fourth defective whites. Breeding merle to full color will
produce one half full color and one half merles, but no defective
whites. The merle to full color breeding, then, produces just as
many merles as does the merle to merle breeding, and without
the danger of defective puppies. The safe breeding for a merle,
then, is to a non-merle mate. This breeding should produce all
healthy puppies, and about half will be merles.

  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
