Information on White Boxers and the Controversy Behind them
Unfortunately, the White Boxer has been the cause of much controversy among breeders and the public for quite some time. I hope that the following information will help dispel any myths that you have heard about the White Boxer.
White boxers are white for the same reasons why humans have blonde, brown, or red hair-through genetics. The parents determine the coat color of the dogs. They are the same in every way as any other boxer with only one main SIGNIFANT difference, their color. Because "white" is not an approved "Breed Standard" color, these dogs are rejected by many reputable show breeders and become UTHANIZED at birth.
-Two Very important "behind the scene" facts to be aware of -
The White Boxer was one of the first colors to establish the Breed.
If it were not for the "'white" gene (therefore the white boxer), there would not be any flashy boxers which are so desirable in both the show ring and by popularity.
Aprox 25% of all Boxers born are White.
Marking Pattern Inheritance
Now we get into the issue of marking patterns. There are three marking patterns in Boxers - solid colored or "plain", marked or "flashy", and "check" or white. Again, there are only two genes responsible for marking patterns, the solid color gene and the marking pattern gene (often called the "white" gene).
Gene for Solid Color (S) Gene for White Markings (Sw)
The number of each gene a Boxer gets determines its marking pattern. Neither gene is dominant over the other, which means that in a dog that has one of each gene you will see a "combination" effect; in this case, a flashy Boxer.
It is important to note a few things here. One is that, like brindling, the marking pattern is affected by modifiers, so that a flashy Boxers, while genetically the same as another flashy Boxer, will not be phenotypically the same - one may have a full white collar, the other may only have white "stockings" and no white on the neck. Also, genetically plain Boxers do have a minimal amount of white markings on the toes, chest and belly. Because of the modifiers, a genetically flashy Boxer that is modified to have only a small amount of white markings may look phenotypically identical to a genetically plain Boxer. Finally, because white is a marking pattern and not a coat color, a white Boxer is always either fawn or brindle. If the white covers the entire body, you may never know which color it is (unless it happened to come from two fawn parents).
