YES! I Said A Brindle

When Brindling is produced on puppies out of seemingly solid Parents,

We have found through research that the brindle can be in some cases a carried gene and is best explained, and is described as followed:

Brindling is 'stripes' of eumelanin-based (can be modified by the genes at the B and D Locus, so the color could be black, blue, chocolate or fawn) hairs in areas that are otherwise phaeomelanin based.  In order to produce the brindle color, at least one parent MUST be a brindle.  Brindle is dominant to its absence, so only one copy is needed.  If a person has a brindle colored pup for sale and there are no brindle colors anywhere in the pedigree, then the sire that is reported on the registration papers --- genetically can not be the (true) sire. 

There is an exception to this if the dog is "e/e" or "K", he can be a carrier of brindle.

B/b d/d e/e = dilute red to pale cream with black nose
b/b d/d e/e = dilute red to pale cream with fawn nose

We believe that in the case of Kathi’s bitch: Pooh and Sire: Wags, both of whom have no Brindling on there self colors, yet when bred together produces a full litter of Brindled puppies.

That Pooh is: b/b d/d e/e br^k = dilute red to pale cream with fawn nose, making her incapable of expressing Black B anywhere on herself, and therefore is fine example of a carrier of the brindle Gene.

Wags is a: at^at B/- D/- E/- k/k = black with tan points, carries no brindle in his gene make-up.

When Bred together these to dog where in fact the producers of Five (5)puppies, Four (4) blk/tan brindles puppies, and one (1) blue/tan puppy, The Brindle came from Pooh as a carrier of the brindle make-up.

We know that this can be confusing at times.  Breeding data and DNA data from collaborative study with Dr. Greg Barsh's group at Stanford supports this. Please feel free to research this further as there is so much more to learn on the following website: http://www.kelpies.caviesrule.com/about.html which is just one of many out there that we have been to.
