I hope that if MaryJo is a carrier, there will be evidence of it. Either way, I'm not keeping any of these because dwarf or not, some will be carriers, most likely.
Tell me, what do you like about the Shamos? That is one breed I can't wrap my head around, but then, I don't like Silkies, either, and it's like blasphemy to say that, LOL. If you could tell me why you like them, maybe I could see something different in them. I did not care for Orloffs until I saw one in person, then I realized how handsome they really are. And I have yet to see a chocolate Orpington in person to see what the color really looks like so I can then develop a true opinion from experience, not just photos.
