Long story short, I purchased a bi blue pup. I'd been looking forever for what I wanted. I turned in a merle swab to a university for testing as I was pretty sure she was harlequin merle and I was correct. I have become pretty friendly with this breeder and we talk frequently. The last litter also had 1 pup who looks very similar to my new pup. Bi blue. They also had several bi blacks and 1 tri each litter. I'm baffled because mom to these pups is a blue merle/white/tan with very little white however her pattern is indicative of harlequin. Dad is just solid tri, also with very little white. Just the typical Irish pattern. When researching pedigree, and there are a lot of champions in there so I'm assuming these are knowledgeable people I dont see any! Bi color dogs. If this is recessive, where are these bi color puppies coming from? Any thoughts? Genetics are crazy. Ill also add these are their only two dogs, so she wasn't accidentally bred to another male.
 
Welcome to the forum, Logan. Although I do not have an answer to your question, I know others in the forum who are knowledgeable in genetics! Do you have a picture of your new pup you can share? if you have a social media account you can just share the link here. Congrats on your new pup!
 
Hi Logan and welcome!

"Harlequin" isn't a term that I've heard used in Shelties... could you describe (or better yet, take a picture) of the coloring you are talking about?

The bicolored puppies aren't really a mystery, if both parents were bi-factored (see the calculator that Daisy1015 linked to above). I wouldn't call it a "one in a million" chance; there are plenty of bi-factored Shelties (of both colors) out there.

Lol No my multiple kids being left handed to right handed parents was the rare event as my example of recessive genes - not the bicolors being rare. Maybe my analogy was poorly spoken or confusingly written. I was trying to point out it was possible for recessive genes to show up.
Maybe a better example is a breeder who bred two “pure for sable dogs” but somewhere way back in the lines was black. And ended up with her first ever tri- became a champion though!
