Genetically, your girl is a black and tan. (POSSIBLY with a single copy of the silver gene)
The “white” dog was most likely a VERY faded sable that carried the genetics to produce this.Either that, or the dog you are calling “clear red” was not really, and was a red sable, where the black tips had been cut off his coat, making him LOOK like a clear red. that confuses many people including breeders. I have seen MANY dos listed in the HVanese Gallery as “red”, that are CLEARLY red sables. Was genetic testing for color done on either of the parents?
