I am a bit confused on the parti color thing. I have always wanted a parti color yorkie and last week 3 yorkies were born at the shelter. One came out parti colored. Since it was a rescue situation I can't say for sure that the mom is a purebred and we don't know what dad was but the other 2 pups came out looking very yorkie like. If the mom is a purebred she is not well bred, she has a bit of an underbite. It just got me curious. Is it just a recessive gene that randomly pops up or does having a parti in the litter mean it's probably mixed? There's a pic below, the parti color is hiding by moms head. I know some of you are way more knowledgable about this than me! Thanks
