Australian Shepherds have the rarest features of the breed, which is why they are known as the Australian Shepherds. They have blue eyes and are known to be very intelligent and very good at reading human emotions. They are good at catching and retrieving, which is why they were used in hunting and then as guide dogs for the blind. Blue eyes are a genetic trait passed on from generation to generation. The blue eye gene is found in the same gene pool as the black eye gene. The only difference between the blue and black eye genes is the colour of the iris.
This means that if you have a parent with blue eyes and one with black, you will likely have either blue or black eyes. The blue eye in Aussie is because of a gene lack of melanin. The lack of melanin is caused by the pheomelanin gene, which is recessive. Melanin is a pigment that gives color to the iris and skin. Without it, the eye would be white. It is formed in the iris and skin cells by a pigment called eumelanin. Eumelanin comes from the amino acid tyrosine.
The heterochromia/Merle gene disrupts melanin production and is found in the same gene pool as the blue eye gene. This means that if a parent Australian Shepherd has blue eyes and one with merle, then pups will likely have either blue or merle eyes. This does not mean that you will necessarily have one of each eye color, though, because each parent Aussie can pass on either color trait to their offspring if they are both carriers.

How Do Australian Shepherds Get Heterochromia?
There are several different theories on how heterochromia occurs. Some say it is a genetic mutation, where one of the parents passes along the gene, and it isn’t seen in the other parent’s offspring. Others say that a virus or bacteria could cause it. Other theories include injuries from the environment, such as radiation or pesticides. In any case, heterochromia is a genetic mutation, and it is believed that the genes that cause it are on the X chromosome.
The gene that causes heterochromia is called Merle. It is found on both the X and Y chromosomes. The merle gene can be passed down to both sexes, but only one sex will express the male or female trait. If an Australian Sheppard has homozygous merle, they will have both blue eyes (no melanin) and merle (darker than normal). If a Sheppard has heterozygous merle, they will have one blue and one black eye.
They will also be homozygous merle, but they will only have one merled eye instead of two.
Is Heterochromia Bad For Dogs?
It is two eye colors at the same time. The answer is No; heterochromia is not a problem for dogs. Heterochromia is a genetic mutation that does not cause any health problems in dogs. It is seen as a desirable trait in some breeds of dogs, such as the Australian Shepherd. Eye color does not affect a dog’s health in any way; however, some people find it interesting to see how different eye colors affect a dog’s appearance. Hetrochromia is common in many breeds including huskies.
Heterochromia can be passed on to offspring, but it is not as common as other genetic mutations such as merle. It is also not usually seen in purebred animals. A dog’s eyes can be blue, brown, or any shade of gray. Heterochromia is just one of the many possible eye colors found in dogs. As mentioned above, the eyes can be blue, brown, or gray. The eyes can also be white or yellow.
What Is The Rarest Eye Color For Australian Shepherds?
Australian Shepherds have many rare features. One of the rarest eye colors for Australian Shepherds is the clear-eyed variant. This color is not common in any breed of dog. A clear-eyed Australian Shepherd has a blue or brown eye color with no white. This gene is very rare in dogs.
The most common eye color for Australian Shepherds is blue. This type of eye color is the most common in the general population of dogs. Blue eyes are a feature of many breeds of dogs, including Labrador Retrievers, Golden Retrievers, and Poodles.
Moreover, green is also very rare in Australian Shepherds. Green eyes are also very rare in dogs. The green eye color is not common in any other dog breed. The gives Australian Shepherds a special look and makes Australian Shepherds stand out in the dog world.
Is Blue Eye In Australian Shepherds Mostly Favourite Of People?
Different people have different tastes in dogs. Some people prefer brown eyes. Some do green, and some both. Most people love blue eyes in Australian Shepherds. Blue eye color is a very rare feature in dogs. Many people look for blue eye dogs when buying an Aussie. Blue eye is also very common in Australian Shepherd breeds, such as the Australian Silky Terrier and the Australian Kelpie.
It may depend on people too. Like some people prefer brown eyes in dogs, and some prefer dark red. It all depends on the choice of each person.
What Are The Common Eye Problems In Australian Shepherds?
Australian Shepherds are very healthy dogs. But some eye problems can occur in Australian Shepherds. The most common eye problems for Australian Shepherds are described below:
It is a condition where the lens of the eye becomes cloudy with age, which can cause blurry vision and see double. Cataracts are one of the most common eye diseases in dogs. It occurs when the lens becomes clouded with age. Aging, certain medications, or diseases such as diabetes or thyroid disease can cause this disease.
Glaucoma is when the pressure inside your eyes increases, causing damage to the optic nerve. This damage causes vision to become blurry and double, especially at night when you are trying to sleep or driving on a dark road.
Glaucoma usually occurs in older dogs, but it can also develop in younger dogs if they have other health problems that increase pressure inside their eyes, like cataracts or diabetes mellitus (low blood sugar).
Diabetes Mellitus (DM):
DM is a condition that occurs when your blood sugar levels are too high. This can be caused by either a lack of insulin in the body or the pancreas cannot produce enough insulin to keep your blood sugar level normal. Diabetes mellitus affects both eyes, causing blindness and damage to the optic nerve.
It can be cured with diet and medication. Diet is an important part of the treatment of diabetes. A diabetic dog will require a special diet to control his blood sugar level and prevent further damage to his eyes and body.
Progressive Retinal Atrophy (PRA):
PRA is a degenerative disease of the retina that causes the death of the retina’s photoreceptors. PRA usually affects older dogs and is usually caused by a genetic mutation in the dog’s cells. It is not always fatal, but it does lead to blindness and loss of vision. Certain medications, diseases, or conditions such as diabetes, kidney disease, or thyroid disease can also cause PRA.
Pannus (chronic superficial keratitis):
Pannus is a chronic inflammatory degenerative condition of the cornea and conjunctiva. It usually affects older dogs, usually after the age of seven. Certain infections or diseases, such as diabetes, can also cause it. Pannus causes pain and loss of vision but does not lead to blindness.
Refractive errors are changes in your Aussie vision caused by an error in focusing on objects far away, close up, or far and near. Both eyes can suffer from refractive errors, but they affect your dog’s vision differently. If you have recently lost your dog’s sight, he may have developed a refractive error that you may never have noticed before his loss of sight.
If so, it is important to determine what type of refraction error your pet has before treating it if you don’t already know what type he has developed over time.
Many people love Australian Shepherds, and many of them are very protective of their families. Aussie Shepherds are known to be very intelligent, energetic, and loyal dogs. They come in many varieties and have distinct features that make them unique.
There are famous for their beautiful eye color. Blue eye color is the most common eye color. Eye color can be determined by the amount of melanin in the iris, the shortening of the iris, and the amount of pigment in the coat. Blue eyes are caused by a recessive gene and can be found in various breeds, such as; Labrador Retrievers, Poodles, and Australian Shepherds.
