The only way to get a Biewer if one of these babies is bred to a standard Yorkie, is that the standard Yorkie must also have the Piebald gene. Then it would be a 1 in 4 chance of a Biewer pup. Sometimes you can tell if they have the piebald gene as they have the white on their chest. Each of the Yorkie pups in this litter have white on their chest, some quite a bit of white. |
