Of all topics of discussion, coat color and markings will get the most heated debate. Most will tell you everything you want to know about color and markings, but know very little about structure, form, and function.
The only thing in regards to coat color and markings to know is:
It is 5 points of the 100 points. The standard allows FIVE points. Keep it in perspective.
Once you get the REQUIRED MARKINGS, everything else is just the icing on the cake. The important thing is to be able to recognize what is required and what is a disqualification.
Pictured are four representative specimens of the Boston terrier. Of these four, three have noticeable disqualifications and one is acceptable per the standard.
You be the judge! Which of these dogs is NOT a disqualification?
Per the AKC Boston Terrier standard “color and white markings” is a particular, distinctive feature of a representative specimen.
Boston terriers must have a complete white muzzle band, as well as a complete white forechest. No where in the standard does it say it can have a black/white forechest or a black/white muzzle band.
Per the standard: a dog with a preponderance of white on the head or body must possess sufficient merit otherwise to counteract its deficiencies.
Boston terriers must be brindle, seal, or black with required markings. All other colors are a disqualification. The absence of the required markings is also a disqualification.
