Nose and Coat Colors

Blue nose dogs are actually gray in color and there is a fascination by many people with the “blue” coat color. As a result, many of them are out searching for a blue-nosed dog but, there can be some health issues with recessive genes.

The Fascination with Blue Nose Dogs

Pit Bulls come in an array of amazing colors and one of the more popular colors is “blue nose.” The terms “blue-nose” and “red-nose” are frequently used in pit bull circles. There are many people looking for Pit Bulls who “think” being a blue-nosed pit bull makes them unique. But in reality, there is no real difference between a blue-nose pit bull and other pit bulls. Blue-nose pit bulls are not a separate breed or even a bloodline. It is just a defect in one dog’s genes, which has been bred into the dog, in fact, bre with a non carrier of the recessive gene it could quickly disappear in puppies,

“Blue” is a common term in the dog world to describe a gray color that ranges from light silver to deep charcoal.

Blue-nose Pit Bulls have a gray or near-black nose and a gray coat that is “blue”.

  • Blue-nose pit bulls are normal dogs who simply display a particular color pattern. For example, they have “blue” actually “gray” coats, and their noses match their coat color.
  • Gray Dog does not sound as unique or exciting as Blue Dog.
  • Aside from this coloration, they do not exhibit any significant differences from other pit bulls.
  • Like all pit bulls, blue-nosed dogs are generally friendly, human-oriented dogs who make good pets for suitable families.

Understanding Dog Coat Color

In fact to understand blue-colored dog coats a little better, you have to look at genetics. These genes affect the amount of melanin in every hair shaft from head to toe, making your dog dark, light, or a mix of colors. 


Despite the wide range of dog colors and coat patterns, there are only two basic pigments that underpin them all: (pheomelanin) and black (eumelanin). In simpler terms, blue nose Pit Bulls are not blue instead, they exhibit an appearance best described as diluted black.

Selective Breeding and Recessive Genes

The problem with this type of color is that to retain this blue color; there does have to be pretty selective breeding. Breeding with their family member and as a result inbreeding of dogs can have its consequences. Blue coloration is a recessive gene, and you would need two parents carrying the same gene to make a blue puppy. It also means that blue-nosed pit bulls can produce non-blue offspring.

Skin Issues

Pit Bulls with Blue Coats are More Likely to Have Skin Issues

There are some slight health differences associated with the blue coloring. The beautiful blue-gray coat of blue-nose pit bulls is a rare and sought-after color by fans of the breed. Unfortunately, the recessive gene responsible for the striking coloration, along with poor breeding practices, also makes this coloration type one of the most prone to skin disorders among pit bulls. As a result, they tend to have more skin allergies and alopecia, or thin, dull hair that appears in adolescence and can continue throughout their lifetime.

Blue Dog Personalities

Some dog fanciers think that personalities vary by the dog’s color, but this is not true. Truthfully personalities vary from dog to dog. Personalities are affected by breeding and rearing and the color of the coat has nothing to do with it. Base your choice of a dog on temperament and personality, not on color. Remember, a dog is an individual, and anything you may have heard about specific colors may not ring true with the dog you get.

Don’t let color be your only consideration when choosing a dog for your home. When adopting a pit bull, temperament and personality are far more predictive of successful placement.
