Do dogs with two different colored eyes go blind?
Do Dogs With Heterochromia Have Health Problems? While it’s commonly believed that different colored eyes in dogs is a sign of blindness or vision problems, dogs with hereditary heterochromia have normal vision.
What does it mean if a dog has one blue eye and one brown eye?
Most of the time heterochromia is an inherited genetic occurrence, but occasionally it can be a result of an injury. If your dog sustains an injury to their eye, or they develop a disease of the eye, they can sometimes experience a change in their eye color.
Do dogs with different color eyes have health problems?
Heterochromia is caused when there is a lack of pigment melanin in all or part of one eye. Most dogs with hereditary heterochromia do not have any related health problems. However, acquired heterochromia can be a symptom of several eye conditions.
Is heterochromia caused by inbreeding?
Though common in some breeds of cats, dogs, cattle and horses due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity….Heterochromia iridum.

Do dogs with blue eyes have vision problems?
In some dog breeds, blue eyes can be an indicator of possible vision defects. However, they do not necessarily mean a blue-eyed dog will eventually go blind. While Siberian Huskies and other breeds normally have blue eyes, in other breeds this eye color occurs when two merle-colored dogs produce offspring.
What is a cryptic merle?
A cryptic or phantom merle is a dog which phenotypically appears to be a non-merle (solid-colored) or a dog that has very faint patches of merle that can go unnoticed. Animals that do not present the merle phenotype may possess the merle genotype and subsequently produce merle offspring.
Can heterochromia cause blindness?
A: While it is rare and quite uncommon, heterochromia can cause blindness when coupled with pre-existing conditions such as inflammation of the eye. As a side effect of the disease itself, blindness is not commonly reported in people who have heterochromia.
Can heterochromia cause vision problems?
It can appear in someone with no family history of heterochromia. In most cases, it’s a benign condition not caused by an eye disease, nor does it affect vision. So it doesn’t require any type of treatment or diagnosis.
How common is heterochromia in dogs?
Heterochromia is most common among the following 15 breeds. Heterochromia iridis is more frequently observed in Huskies, Dalmatians, Australian Shepherds, and Australian Cattle Dogs. While the other two types of heterochromia are more common in general and more often seen in the remaining breeds.
Do blue-eyed dogs go blind faster?
Blue eyes does not indicate that your dog will eventually go blind, deaf, or have any other genetic defects. Variation in pigmentation in the iris can occur for varying reasons, and doesn’t necessarily point to health concerns.
Is merle a defect in dogs?
An autosomal, incompletely dominant trait, merle coat coloring predisposes dogs to inherited deafness. When inherited in the homozygous state, the merle mutation causes dogs to be white and have an even greater incidence of deafness, blindness and sterility.
How can you tell if your dog is merle?
If a dog carries the merle gene, the gene often shows up in the patterns on the dog’s coat, but not always so you can’t be sure if a dog carries the merle gene or not. A merle coat has patches of mottled darker colors splashed across lighter versions of the same color.
Can you fix heterochromia?
Typically, there’s no need to treat heterochromia if it isn’t caused by another condition. However, if you want both your eyes to have the same color, you may want to wear contact lenses.
Can heterochromia be fixed?
Do dogs with blue eyes have more eye problems?
Genetically, blue eyes are typically no indication of health issues; however, dogs with genetically blue eyes have been linked to having hearing impairments, according to Washington State University.
Which dog breeds are more likely to have different colored eyes?
Genetic studies along with breeder and dog owner reports to date tell us that these dog breeds are more likely to produce puppies with different colored eyes: 1 Huskies 2 Shetland sheepdogs 3 Alaskan Malamutes 4 Dalmatians 5 Border Collies 6 Beagles 7 Welsh Corgis 8 Great Danes 9 Dachshunds 10 Australian Shepherd dogs
What is my dog’s eye color?
When your dog’s eye color is determined, different factors play a role. If you have a purebred dog, some breeds have specific eye colors based on genetics and coat color. Others can vary depending on the chromosomes that cross. The most common eye color for dogs is brown while the rarest is green, but it depends on both parents.
What kind of dog has blue eyes?
Siberian Huskies have another blue gene that is set apart from the rest. Some dogs who have blue eyes might be prone to more health issues, but Huskies are exempt in this category. Albino dogs have a severe lack of melanin, resulting in an icy blue color, regardless of the breed.
Why do some dogs have one eye darker than the other?
Rather, researchers think that the piebald or merle color gene influences both deafness and heterochromia, so dogs that carry those color genes may be more likely to exhibit both heterochromia and deafness. In most cases, dogs with one lighter eye and one darker eye can still see out of both eyes.
