Hi - your best bet is to contact someone from one of the breed clubs listed at the bottom of the
Breed Standard. It should go without saying that the welfare of the bitch and puppies is more important than her coat. If her coat is correct it can be tied up out of the way. A black coat however is incorrect for the breed (as you will see from the standard) so with luck, if it is cut (only her belly hair would need cutting anyway) it will grow back the correct steel blue.
Good luck.
