What Is a Blue Merle Sheltie?

A blue merle Sheltie is one of the color varieties of the Shetland Sheepdog. It is classified as a tri-color Sheltie that exhibits the merle gene. This gene is responsible for the gray and blue hues in blue merle Shelties. These hues are seen among the patches of black, white, and tan on its coat.

Other official Sheltie coat colors are sable, tri-color, bi-blue, and bi-black. Some may have an abundance of white fur, referred to as white-factored Shelties. A well-known example is the color-headed white (CHW) Sheltie

Shetland Sheepdogs are just one among the several different types of shepherd dog breeds, but what separates Shelties from the others is their sweet nature, a trait considered uncommon among herding dogs.

A blue merle Sheltie is no different. These delightful pups are widely regarded as the epitome of all herding canines due to their versatility, intelligence, and warm-heartedness.

Are Blue Merle Shelties Rare?

Blue merle Shelties are not as rare as other color variations of the Shetland Sheepdog. In fact, as an officially recognized coat color by the American Kennel Club (AKC), blue merle is one of the most popular variants.

While blue merle Shelties are not particularly rare, some of them may be “cryptic.” This refers to blue merle Shelties that barely exhibit the merle pattern, therefore appearing tri-color instead.

In producing a blue merle Sheltie, only one parent must possess the merle gene. If both parent dogs have this gene, there is a one in four chance of creating a double merle Sheltie.

Double merle dogs are also known as “lethal whites” because of the numerous instances of blindness and deafness found in these pups. This is due to the connection of the merle gene with ocular and auditory issues.

On a different note, the most common Sheltie colors are sable and white and tri-color, which is a combination of black, white, and tan. On the other hand, the rarest official color variation is black and white or bi-black.

Blue Merle Sheltie Appearance

Blue merle Shetland Sheepdogs bear a very strong resemblance to Border Collies, to the point that they may be mistaken as miniature Border Collies. 

However, these pups are smaller than their Collie cousins. They are medium-sized dogs standing at 13 to 16 inches tall and weighing anywhere between 14 and 20 pounds,

Unlike with other dog breeds, the difference in size between male and female Shelties is minimal. Usually, males will be a couple of inches taller and not more than five pounds heavier than females.

Sitting on their wedge-shaped heads are small, erect ears whose tips bend forward slightly and long, narrow muzzles. Shelties also have an athletic frame.

Their beady eyes are usually dark in color, but the merle gene can sometimes affect pigmentation in the eyes. This means there is a chance of blue merle Sheltie puppies having blue or light-colored eyes.

Shelties are double-coated, which keeps them well-insulated in cold weather. Their long, harsh coats – which gather into a mane around their head – shed moderately, especially during shedding seasons.

As mentioned earlier, blue merle Shelties are primarily characterized by a combination of black, tan, and white, with mottled patterns of blue, gray, or silver across their coats. 

Blue Merle Sheltie Coat Color Genetics

The signature color and pattern found in a blue merle Sheltie are caused by the M-allele, which is either dominant (M) or recessive (m). Merle coats are associated with having one dominant M allele.

The M allele or the merle gene affects the eumelanin pigment of Shetland Sheepdogs by diluting black colorings into irregular gray, silver, or blue spots. 

Aside from the dog’s coat, this can also affect its eyes, nose, and toe paddings.

Blue merle Shelties are usually created by crossing tri-color or bi-black Shelties carrying the merle gene to another Sheltie that does not.

This breeding has a fifty percent chance of producing a blue merle Sheltie puppy with the M/m genotype, meaning they have one dominant and one recessive M-allele, respectively.

Since it is possible for a Sheltie to carry the merle gene without expressing it, the process of breeding blue merle Shetland Sheepdogs should start with DNA testing. This is to identify if the parent dogs possess the merle gene. 

If a breeder is unaware of the genetic backgrounds of the potential parents, there is a chance of breeding two merle dogs together and producing a double merle puppy. 

Double merle pups are often afflicted with developmental issues of the eyes and ears, resulting in deafness and blindness.

Blue Merle Sheltie Temperament and Personality

A blue merle Shetland Sheepdog will always be a joy to have around. These pups are known to have sweet and bright personalities complemented by their intelligence and diligence.

It is important to note that the color of a Sheltie does not influence its personality; therefore, the temperament of a blue merle Sheltie will likely be similar to other color variations of this breed.

Shelties have long histories as herding dogs, so expect blue merle Shelties to be naturally adept herders and working dogs. They will thrive when given a task, especially if rewarded with affection. 

A behavioral trait that comes from this is excessive barking, but this can be remedied through positive reinforcement training. Ample physical and mental stimulation is also necessary to keep this dog happy.

Shelties are highly intelligent and trainable breeds. Their obedience and adaptability pair well with their loving and affectionate temperaments.

All in all, blue merle Shelties are versatile pets that can thrive as either working dogs or just family companions. They are charming, lovable balls of energy that will bring a smile to anyone that comes across them. 

Blue Merle Sheltie Lifespan and Health Issues

As with other Sheltie variations, the lifespan of a blue merle Sheltie is 12 to 14 years. This is a generally healthy breed, especially with proper diets, ample exercise, and regular upkeep. 

However, Shetland Sheepdogs have some common health issues that owners should look out for. This is especially true with blue merle Shelties because the merle gene is closely linked to some developmental issues.

Here are some examples of health problems a blue merle Sheltie can face:

  • Hip Dysplasia: Canine hip dysplasia is a common ailment affecting a blue merle Sheltie’s hip joint and pelvis. During the development of these areas, the hip socket grows at a different rate than the ball or femur head. As a result, the joint becomes loose and deformed, which causes pain, limping, and difficulty walking. 
  • Obesity: Blue merle Shelties can be very food-centric creatures, which can, unfortunately, lead to canine obesity if left unchecked. Excessive weight will put a strain on the bones and joints, which can cause or worsen body pain or degeneration.
  • Dental Diseases: Oral health is important to most dog breeds, particularly for Shetland Sheepdogs. These pups are prone to buildups of tartar or plaque, which may progress to an infection of the teeth and gums. In worst-case scenarios, periodontal issues can also harm a dog’s kidneys, liver, heart, and joints. 

Because of the connection between the merle gene and certain illnesses, owners should also look out for eye diseases like cataracts and distichiasis. 

Health issues like obesity and dental problems are fortunately preventable with proper care and maintenance. Regular visits to a trusted veterinarian are also highly recommended, especially in identifying genetic illnesses.
