"Black" puppy - update with photo - Page 2

Is it even genetically possible for him to be black? Doesn't look like the father has a black recessive and I don't see it in the pedigree. Were any other puppies in the little black? Were any puppies black and tan? If any of the puppies in the litter are black and tan, then it's not possible for this puppy to be a solid black, genetically.

Genetically, the sire, as a sable, can have 1 gene for sable and 1 for something else--in his case, black and tan or black are the options (maybe white or bicolor, but those are pretty unlikely and don't seem to apply here, so we can ignore those possibilities).

If the pup is sable, then the gene it got from dad is the sable gene. If the pup is black, it would have had to have gotten the black gene from dad and a black gene from mom. Therefore, dad would be Sable/Black--and there would be no black and tan pups in the litter.

So, dad's genetic pattern options are Sable/black or Sable/bt. Mom is black, so she is black/black. So, the pups colors will be some mix of those 4 options--either

Color options for the puppies are:

  (dad has black recessive)
1) Sable w black recessive and Black/black--making a black dog

OR

(dad has black/tan recessive--mostly likely chance based on pedigree and phenotype [he's a saddle-patterned sable without black toemarks and heels])
2) Sable with black recessive and Black/tan with black recessive

Option 2 could theoretically produce a black sable.

Interesting coloration on a very handsome puppy. It will be fun to watch how he develops.




If

Puppy most probably sable...but lift tail, if there is any brown under tail above rectum then puppy is NOT black and shedding off color undercoat it is definately a sable dog. In any case this is a beautiful dog.
