Will a Bichon and liver Shih Tzu breeding produce liver puppies?

Question

Genetically, can a registered bichon reproduce liver puppies with a liver shih tzu, or would a bichon not be able to pass on the liver nose gene? Pet's info: Dog | Shih Tzu | Female | unspayed | 11 lbs

Dr. Strydom, DVM · Accepted Answer

Bichon dogs do not have the liver gene and therefore cannot pass on this trait. The nose is not what makes the dog liver; it is the skin color (which includes the nose). Shih Tzu's can either be liver or black (skin); liver is recessive to black. This means that in order for a Shih Tzu to be liver one of the following three scenarios must occur: 1) Both parents are liver (bb x bb) 2) One parent is liver and the other is a carrier (Bb x bb) 3) Both parents are carriers. This means a livers can be produced by a sire and dam that do not appear to be liver at all. They both carry the recessive gene. (Bb x Bb) Two dogs that have black skin and do not have the recessive gene are BB and cannot pass on the gene. Hope this helps. Best wishes.
