This type of Border collie is becoming increasingly popular. We are talking about the Border Collie Blue Merle.

What is a Border Collie Blue Merle?

A Border Collie Blue Merle is a variation of the Border Collie breed that has a distinctive merle coat pattern. The term “merle” refers to a mottled or marbled coat pattern that can be seen in a variety of dog breeds. In the case of the Border Collie, the merle coat can be blue, black, or red. The blue merle coat is characterized by a mix of blue, black, and gray hairs. All these traits create a unique and striking type of border collie appearance.

The Merle Gene in Blue Merle Border collies

The merle coat pattern is caused by a gene known as the “merle gene.” This gene affects the way that the dog’s coat develops, resulting in the unique marbled pattern. The merle gene is a dominant gene. This means that a dog only needs to inherit one copy of the gene from one parent to express the merle coat pattern.

However, in many cases, both two dogs carry the merle gene. When they breed together, there is a 25% chance that their offspring will inherit two copies of the gene. This results in a condition known as “double merle”. Which can cause a variety of health issues such as blindness, deafness, and other genetic disorders.
