Not at all, look closely they are all BMH.
My boy came from a litter of twelve, two were black him and his sister who belongs to a member of this forum. Please do not judge by a couple of pictures that you have seen on thi site, their facial characters are the same probably differant picture angles portray a differant picture, internet search you will see many.
My lad came from lines that are dark, stag red described. I was in Poland the other week and travelling from one location to another I saw two BMH in a garden with tracking collars on, they were the same colour as my boy’s parents.
