sable and white English Shepard. I think I can post a picture of my dog. I wish I could just paste it. I have to up load it some place else first, then link it, right?
English Shepherds are generally pretty healthy. As a breeder, you have an obligation to do your best to keep the breed that way.
Spend time reading about genetics in general and the genetics of the breed specifically.
Unless you understand genetics and any issues involved in breeding, it is inadvisable that you proceed.
