You may have noticed that on our adults page, some of the dogs are listed to be "Red Factored".  In Australian Shepherds, the B-Locus determines if a black or blue dog will be able to produce red offspring. If the dog tests B/B, that dog does not have the red gene, and will never have red offspring. If the dog tests B/b, that dog does carry the red gene thus making him/her "Red Factored". Breeding to another carrier or to a red dog should produce red offspring. Dogs that are actually red will test b/b.
