Historical Background
The origins of the Blue Merle Sheltie can be traced in the Shetland Islands of Scotland, where the breed was also known by the locals as the Shetland Sheepdog.

It was only in 1911 when the American Kennel Club officially recognized the Shetland Sheepdog as a breed, and today they are a popular companion dog around the world.

Genetic Composition
The Blue Merle coat color in mini Sheltie puppies is the result of a complex genetic process.
It became the way it is because of a gene mutation that affects the way pigment is distributed in the fur, resulting in the characteristic patches of black, gray, and white.
The gene responsible for this coloration can also cause certain health issues in some Shetland sheepdogs, such as blindness or deafness.
To avoid these problems, breeders should only mate dogs with healthy genes, and carefully screen their puppies for any genetic issues.
