It is good to ask questions. I have never seen a Biro. I think there was one for sale on Puppyfind the other day, but I have not seen one in person.
The standard for the Biewer is 4 white legs, at least the tip of the tail is white, the chest is white, and 2-3 colors in the face. There is no minimum or maximum of the amount of black on the body. That is preference for a lot of people--the amount of black or white on the body. |
