How Do You Describe the Jack Russell Terrier Coat Pattern?

Combination of Colors That Make Up a JRT’s Coat Pattern

Two types of melanin pigment determine hair color in these dogs. They include:

  • Eumelanin pigment that is responsible for black and brown pigment
  • Pheomelanin pigment that is responsible for red and yellow pigment

Jack Russells have unique genes that interact with melanin producing the varying pigments of black, brown, yellow, and red that decorate their white fur coat on different parts of their body. Common variations of fur coat color on the dog include:

White

White Jack Russells are rare as most white puppies will develop color patches as they grow. Taking your white ‘Jackie’ for veterinary checkups is often essential because white Russells have a higher chance of developing congenital deafness.

Tri-colored

These Russels have a combination of white, brown, black, and tan patches on their coat. Most of the dog’s body is predominantly white with irregular patches of black, brown, and tan on their face, saddle, or tail.

Black and White

The unique fact about black and white Russell terriers is that they are not exclusively black and white. They will look black and white; however, they have mixes of tan and brown color bases that are not easy to see under their fur coat.

Red and White

These Jack Russels have a red base with big patches of white fur. It gives the impression that they are predominantly white while, in actuality, they have a red-brown base.

Chestnut and White

Jack Russell Terrier’s genes in this combination dilute the Eumelanin black pigment responsible for the black color. This dilution results in a white dog with dark brown patches

Tan and White

When Russell Terriers’s genes dilute the Pheomelanin red pigment, it produces a tan color. This genetic effect leaves the dog white with tan patches on the body, especially on the back of the ears and cheeks.

Lemon and White 

Terriers with this color pattern are generally white with small patches of lemon-yellow color. These lemon patches preoccupy the muzzles and saddle of the dog’s body.

Effect of Jack Russell Terriers Fur Types on Its Coat Pattern

The fur type of a dog can affect how you will see the color of your dog’s coat. A Jack Russell Terrier can have three coat types. Jack Terriers can have a:

  • Smooth Coat – A thin, smooth layer of short fur measuring about 1cm-1.5cm in height.
  • Rough Coat – A dense layer of long shaggy fur measuring up to 10cm long.
  • Broken Coat – A combination of a smooth and rough coat where some areas of the dog’s body have short fur while some regions are denser and more shaggy.

Small dot-like patches of black or brown color on a rough coat Jack Russell Terrier called tickings might not be visible with a thick fur coat. A rough fur coat can result in the Russell Terrier’s white fur covering patches of colored areas affecting its appearance.
