Brown Boston Terrier Color Genetics

The Brown Boston Terrier’s color is determined by a pigment called eumelanin. This is a type of melanin responsible for the colors black and brown in dogs. The white markings on a brown Boston Terrier are caused by a lack of melanin. 

Most brown Boston Terriers are actually brown and white. Pure brown Boston Terriers are rare. 

Brown Boston terriers get their color from gene interaction. One gene determines the color of the dog. Another determines the lack of melanin on the white markings. A third gene determines where on the dog’s body the markings are placed.

Together, they make up the genetics of their coat color and markings.

Some Boston Terriers display a stripe pattern similar to tigers but with lower contrast. This pattern appears as black stripes on a brown base.

Brown Boston Terriers with a brindle pattern fall into the category of brindle Boston Terriers.

The brown Boston Terrier is often mistaken for the red Boston Terrier as the colors are similar.

In terms of color genetics, brown Boston Terriers are different from red Bostons. The red Boston Terrier has a reddish liver color that is determined by a different melanin type called pheomelanin.
