I received permission today to add some photos of Panda Shepherds to the photo gallery. I will also add them to the white patterns page but am waiting on a bit of information before I do. From what I can gather the Panda mutation was a spontaneous mutation. The breeder was quite surprised when one of her pups came out with white. The mutation is embryonic lethal when homozygous. I haven't been able to verify the gene locus yet. I did email the researcher at UC Davis so hopefully he will get back to me. These are some beautiful dogs with a very interesting pattern.
