Can Beagles Have Blue Eyes?

Even though the beagle is a breed of dog that has been around for generations, there is one feature about them that you probably need to be aware of. Blue eye coloration in beagles results from a very uncommon genetic variant. 

It is not in the DNA of purebred beagles, although beagles with specific mutations or phenotypic variants might develop this trait. Finding a dog with blue eyes is challenging but rewarding. If your Beagle is a purebred, there is a good chance it does not have the genes that cause blue eyes somewhere in its system. ‘

Despite this, there is a remote chance that the beagle will have blue eyes due to an unusual genetic mutation. There are a few explanations for why this takes place:

Reasons for Beagle’s Blue Eyes


A change in an animal’s DNA, known as a mutation, might alter its qualities by introducing novel methods for those characteristics to manifest themselves in the animal. For example, if a beagle pup was born with blue eyes, one of its parent’s genes had a mutation that led to the trait. 

Even though instances like this one are incredibly uncommon, it is nonetheless possible for dogs to acquire mutations that cause them to seem different. This gene can be handed on to subsequent generations of children. 

A mutation can take place in the location where the recessive allele is expressed. Radiation or bacteria are two potential causes of this condition, which occurs seldom and is not passed on to the dog’s children in a genetic or hereditary form.


The disorder known as albinism is caused by a mutation in the gene that encodes pigment (tyrosinase). This results in hyperpigmentation, which indicates that neither pheomelanin nor eumelanin is produced in the affected area. 

Melanocytes are responsible for the production of pigment. The eye color changes to a blue hue when melanocytes, which produce melanin and pheomelanin or eumelanin, are absent.

It’s possible that both of the parents had a mutation that made them carriers of the gene, but they were unaware of it. 

It is not necessary for both parents to carry the mutation for albinism to be passed along. Or, this may be the result of a previously undiscovered mutation that happened at this particular time and place.

Mix Breed

A dog with parents who belong to two separate pure breeds is said to be a “mixed breed.” The offspring of two different breeds might take on the appearance of either of its parents yet still retain both characteristics.

Brown can mutate into blue; the shade of blue can also change depending on what other breeds are mixed in with the beagle. Because of this, some beagles may have blue eyes. 

For instance, mixed breeds such as Huskies and Border Collies can contain the gene for blue eyes, meaning that beagles might theoretically have blue eyes. The likelihood is extremely remote but by no means nonexistent.

Merle Beagles

The Merle gene is a form of genetic variation that may be seen in dogs. This gene influences a dog’s coat, which can lead to the development of spots or lighter-pigmented shades on the dog’s coat.

In a similar vein, it’s possible that the merle gene is to blame for the blue eyes that certain dogs have. Merle dogs are also more likely to have health problems than other dogs. As a result, ensure that you take all the appropriate safeguards when they are called for.

Young Puppies

Beagle pups almost often have blue eyes when they are born, although there are some exceptions. This is because their irises do not have any melanin, which causes this trait. As time goes on and they become older, it will eventually become apparent. 

The hue of their eyes is gradually shifting, and you can see it. This is something that often occurs with the vast majority of puppies. It is a frequent element that gives the appearance that their eyes are clear or blue. When a puppy is born, it may or may not have blue eyes, depending on the breed.

According to observations, the pigment will start to appear gradually as they mature, and their eye color should be standard by the time they are six months old at the very latest. As an illustration, a beagle’s eye color may not change due to this factor. 

As a result of the enzyme that regulates the formation of melanin pigment not being completely formed at such a young age, it does not affect the color of their eyes. However, as kids reach adulthood, the color of their eyes should return to normal.

Eye Diseases

All these factors contribute to the possibility that your Beagle has blue eyes. On the other hand, having blue eyes may be a sign of an underlying eye condition in certain people. One such condition is glaucoma, sometimes known as prenatal glaucoma. 

Beagles Have Blue Eyes

The eye ailment known as perinatal glaucoma is present in your dog from the moment he is born. Because of this, there is a chance that your puppy will be born with totally blue eyes. Among the other symptoms are the following:

  • Sensitivity to the effects of light
  • Eyes with a haze
  • Eyes that are red and bloodshot
  • Dilated pupils
  • Enlargement of the eyeball

Other eye illnesses which may cause your dog’s eyes to seem blue include nuclear sclerosis and interstitial keratitis. Nuclear sclerosis usually is innocuous and happens as the dog ages. On the other hand, it raises the possibility that your dog will get cataracts. 

Therefore, seeing a veterinarian for a diagnosis is always recommended. On the other hand, interstitial keratitis is an inflammatory condition affecting the cornea’s cells. It forms a film over the dog’s eye, which gives the impression that the watch is blue. If your Beagle has blue eyes, this might indicate that he is suffering from a sickness. Immediately seek the advice of a veterinarian.

White Fur Around the Eyes

Because it’s conceivable for a beagle to have white fur around its eyes, this might lead to misunderstanding. The fur will not become blue, but it may appear that way if the light strikes it in precisely the right way. 

If you gaze at it in a well-lit room, the fur will reflect the light, giving the impression that it is blue. But, if you see this color in direct sunlight or from a different angle, the fur will not appear in the same manner; however, depending on how the lighting reflects on it, it may still give the impression that it does.


Finding a beagle with blue eyes is not impossible, even if it is unusual. This may be because their eye color shifts over time or because they contain a mutation that leads to albinism. Your beagle’s blue eyes prove that he is one of a kind and exceptional!
