How Common Is It For Border Collies to Have Blue Eyes? Everything You Need to Know

In Border Collies, the color of the eyes may appear in any color from dark brown to amber or blue. Blue eyes can occur when a puppy gets two recessive genes for this trait. In order for a puppy to be born with blue eyes, both parents must have at least one gene for blue eyes, so if both parents have brown eyes, there is a high chance of a brown-eyed puppy.

The likelihood of a puppy being born with blue eyes is 20% when both parents have at least one blue eye gene. When both parents have two blue eye genes, there is a 40% chance of the puppy being born with blue eyes.

How long do puppy eyes stay blue? The color of the Border Collie’s eyes stays blue until about eight weeks of age, when they slowly begin to change. Blue eyes may become darker before eventually turning completely brown within one or two years. A puppy that has one or two blue eyes at eight weeks of age may have completely brown eyes by one year old.

Puppies with two genes for blue eyes are not always born with them. The color may not show up until the dog is between eight and ten months old. Puppies that have two copies of this gene will always have blue eyes, but it can be hard to tell if a puppy only has one gene for blue eyes because of this late-onset of color change.

In this article, we’re going to clear away any doubts you may have about border collies’ eyes color by discussing all the frequently-asked questions. Keep reading!

What are the chances of Border Collies having blue eyes?

Border Collies almost always have brown, black, or amber eyes. It has been found that about 20% of collies have heterochromatic eyes (blue and another color), but many people think this percentage to be higher – some breeders claim that up to 40% of collies have heterochromatic eyes.

Why are Border Collies mostly not born with blue eyes?

The gene that causes the blue eye color is a recessive gene. This means that both genes the dog has have to be for the blue color in order for them to have blue eyes. The collie breed has been found to only carry one copy of this gene, which means they do not have a pair of genes for the blueness, and thus, most collies are born with brown, black, or amber eyes.

How do people get blue-eyed Border Collies?

People who want to breed a collie with blue eyes can mate two collies together, knowing that both parents will carry the gene for the color. If they have a litter of puppies and one of them has blue eyes, then the other parent must carry the gene for the color as well.

In the Border Collie breed, the color of their eyes can range from a dark brown all the way to a bright blue. So how does this happen?

The gene that causes the white coat of a Border Collie is also responsible for determining if they have blue or brown eyes. If both of a puppy’s parents have blue eyes, then the puppy will have blue eyes. If one parent has blue eyes and one parent has brown eyes, then there is a 25% chance that their pups will have blue eyes. The gene variation responsible for making the coat white results in the absence of pigment in both the coat and the irises of its eyes.

Border Collie Puppy Blue Eyes – Not the Sign of a Cross-Breed!

We receive many enquiries from users and readers about whether or not they can trust their pet’s pedigree papers. Many of these enquiries, sadly, are from people who have been told that their dog was a cross-breed when they thought they had a purebred Border Collie. This is nothing but a fake myth that has no scientific basis.

Does the Blue Eyed Border Collie have a higher risk of health problems?

Fortunately, the short answer is no. The blue-eyed border collies are not any more vulnerable to health problems, deafness, or blindness, than the brown-eyed collie.

The genetic factors which determine eye color are not the same as those involved in deafness, blindness, or other inherited health problems. But this does not mean that blue-eyed dogs are free of at least some health concerns; they may inherit defects, including blindness and deafness, from their parents (and grandparents). Breeders screen for these defects in Border collies before breeding, but not all defects are known. They also screen for diseases like Collie Eye Anomaly (CEA), which is most often linked with blue eyes; it can be debilitating or fatal if left untreated.

Border collies whose parents possess health clearances stand the best chance of not inheriting a genetic disease. It is possible for a puppy to get a genetic disease from a parent even though the parents had no previous signs of that disease.

What is Collie Eye Anomaly (CEA)?

Collie Eye Anomaly (CEA) is a hereditary disorder that affects the eye. It occurs in many breeds, including Collies and Border Collies.

CEA causes the retina to detach from the eyewall, which can lead to blindness if not treated early on. In its mildest forms, dogs with Collie Eye Anomaly may never experience any visual impairment or blindness at all – some may even be completely blind. In its worst form, Collie Eye Anomaly causes the retina to detach from the eyewall at a very young age (prior to 6 months of age).

What does a dog with Collie Eye Anomaly look like?

All Collie Eye Anomaly is characterized by varying degrees of retinal detachment – the retina doesn’t remain in place and pulls away from the eyewall. Severe cases will cause blindness prior to birth or within a few weeks after birth. In milder forms, affected dogs may appear otherwise normal for their age, but have vision impairment.

What Are the Possible Health Risks For Dogs with Heterochromia?

Heterochromia refers to different colored eyes within one animal. It can be both dogs and humans. It is too often confused with other eye problems, such as albinism and sectoral heterochromia.

6 Things You: Can Do To build confidence in a dog

There are no health risks for dogs with heterochromia in the sense that they have a genetic disorder or a disease that they can catch from one another.  However, dogs with heterochromia may experience a variety of risks due to a lack of pigment in their eyes. One example is a condition called uveitis. Uveitis refers to inflammation inside the eye and makes it more susceptible to infection or ulcers developing on its surface.
