I see them all the time. It's random like chimera and only happens in breeds that can have TB in their lines, so no KNN or RID. There are 2 different patterns for manchado so far
completely unrelated to this conversation i'm sorry, but, i swear i saw this really weird phenotype on a WB called Manchago/Manchado something like that.. anyway, wondering if I am going mad because i haven't seen one since and I've tried looking it up XD
