Those unusual mismarks Print E-mail
Saturday, 15 March 2008

Labradors, all The Same. 

I've had telephone calls. "I saw a litter where the puppies looked like mixed breeds, they were black, with flecks or patches of brown on them or yellow with black spots. Mismarks have been well documented in the breed since the beginning.

Don't be so quick to determine that there was any other breed in the wood pile, although, the buyer MUST be aware that Lab puppies with odd marks absolutely might be mixed-bred puppies (this is where you must use your common sense, and gut feelings regarding the knowledge base of the breeder in question). The whole litter will not be mismarked in a Labrador litter. One or two in the odd litter maybe, but not an entire litter.

Mismarks occur naturally in Labradors. They're not mixed breeds at all. They're 100% Labrador. They're not "rare" they're not "bad", they're just mismarked puppies. They can't be shown, but they make as wonderful a pet as their non-mismarked littermates, and are usually sold for less than their littermates. They're everything that a Labrador is. Often, a Sire and a Dam will never produce a mismark again, even though they carry the genes to do so. It's typically a very unusual event, UNLESS, someone has found a specific line that produces it, and is deliberately producing them -- I have only found one case (and they're producing about three to six litters Per MONTH, and does not permit the buyer to see their facilities, but rather delivers them to a meeting location - can you spell PUPPY MILL?). Don't be fooled. There is nothing wrong with a mismarked puppy, but they are *mismarked*.

My intent is not to get into the genetics of mismarks. This is addressed in an article by Pamela A. Davol better than I could ever do it, and if you are interested in words like "nucleotides, gene locus, homozygous, eterozygous, and allele", that article is for you. If not, and you're just a potential puppy owner, and simply want to know that something is possible without going into the genetics of it all, this page is for you.

Sadly, after reading this article through the years, many owners of questionable litters have written to me, asking me to display their obviously mixed-bred puppies on this page as a demonstration of mismarked puppies. Do not allow the breeder of any questionable litter to send you to this page as "proof" that their puppies are purebred. Although respected breeders might send a buyer here to see that mismarks can, and do happen, they'll not send you here to prove to you that their puppies are not mixed. If you've done your homework, and the breeder in question is respected, responsible, and well-known, that's one thing. If the breeder is a back-yard breeder ("we just bred her once so the kids could see the miracle of birth"), you best assume that you are looking at mixed-bred puppies. If the neighbor dog could get over the fence (and bring a few of his buddies along -- there can be mulitple fathers in one litter), you must be careful. You have every right to ask your breeder to DNA the puppy before you purchase a black and tan or brindled puppy as a purebred. There may be one or two mismarks in a large litter, but if most of the puppies in a litter are "mismarked", the litter should be considered highly suspect.

The pictures on this page were sent to me by other breeders.
If any of these were 'borrowed' in error, I will remove them at your request
.
If you are a breeder, and have an unusual or interesting mismark photograph, we would be very interested in putting them here for you. Note: I ask each person who submits a picture the same question: 1. Are the dogs AKC registered 2. are you ABSOLUTELY positive that no mismate may have occurred. Only when these questions are answered in the positive, are pictures added. If I suspect a puppy is not a purebred, it will not be added regardless.

Brindling (or "splashing")
This is sometimes very hard to see. Often, at about four weeks of age, the breeder will notice that the puppy has some mud on its legs. The breeder washes the puppy, and the "mud" doesn't come off. This is often how the first glimmer of brindling is discovered. The brindling often then extends for a time up the legs and on the face and hind quarters, and typically extends no further.
Sometimes, it is difficult to say if the marks are brindling (splashing) or black/chocolate and tan as in the next puppy. Some would call it chocolate and tan, however, the tan markings are not solid, as with the puppies above, and some breeders call it brindling.

The three previous images were submitted by the breeder


The following mismark is a bit of a dilemma.
The breeder said the consensus was that this looks like splashing.
Splashing or no, this is an unusual mismark, and very interesting.

Meet Domino... he has unusual markings, but he thinks it makes him special,
and he is one heck of an obedience dog!
