Black and Tan or Bi Color?
How can one differentiate between the two? I recently got a pup whose sire appeared to me to be a Bi Color. When I got the pups AKC pedigree his father was registered as a black and tan, not bi color. He was an all black dog, only having tan on his legs and chest. From the little I have read, I thought that indicated a bi color. There is no bi color or black in his pedigree, all black and tan. I am just curious about this as I am trying to better understand German Shepherd coat genetics.
Thanks in advance!
