so you're saying that neither dog is merle . . but you can breed them and produce leopard spotted pups? have you done this? does the red dog have any black in his coat? his nails? his nose?
Yep! They are both merle carriers, or "het" for merle if you will. Both dogs had one merle parent. My red dog has no black at all, just tan trim. His nose is liver. I have not done this myself,f but I do know of others who have.
