By: Author Danielle. Crystal blue eyes in dogs are beautiful to look at. Especially puppies with blue eyes tend to get adopted easier than their dark-eyed littermates. But is it even normal for puppies or adult dogs to have blue eyes? You may have heard that blue-eyed Pitbulls are considered undesirable. The APBT community is not amused about this trend for very valid reasons. Color, like everything, is determined by the genetic makeup and developed by the amount of melanin production in your dog.
Melanin is a natural skin pigment that determines how light or dark your skin, hair and eyes are. Less melanin production le to lighter blue eyes, pale skin or blonde hair. A complete lack of pigmentation is called Albinism. In dogs, this low production of melanin can cause a white coat, blue eyes or a pink nose. Melanin production only starts a few weeks after birth and slowly increases with age. The coat color oftentimes influences the eye, nail and nose color.
My Rottweiler, for example, has so much melanin in her fur that blue eyes would be nearly impossible. Their puppy coat will be replaced by a much thicker and darker adult coat when they are 6 months old. Blue-eyed Pitbull puppies are not rare and their eye color will most likely change over time.
That being said, while blue eyes are not particularly rare for Pitbull puppies, not every pup has blue eyes. Check out my Cane Corso colors article for more information on how breeders try to falsely label colors. Breeding for a specific color or coat type should always be a red flag when choosing a responsible breeder. When specific looks are the primary breeding factor, other traits like temperament or health are disregarded.
You might find that the prettiest dog in a litter will have lots of health issues behind the facade. Always make sure that the parents have health certificates and the right behavioral traits you are looking for. Inbreeding in dogs is another huge issue and will be used to pass a certain appearance on to future generations.
As you might imagine, inbreeding comes with the worst health concerns and should never be encouraged. Merle describes a beautiful coat color pattern that can create odd-colored eyes. The merle gene sadly comes with many health issues like deafness and blindness. Double merles MM are extremely prone to these genetic diseases and therefore merles should never be bred together.
A Pit Bull with a merle coat pattern is excluded from the APBT breed standard and might not be purebred because the gene must have somehow found its way into the bloodline. Tyrosinase is an enzyme that controls the production of melanin. Therefore, these dogs will be born with a unique white coat, blue eyes and a pink nose. Albinism in dogs is an extremely rare mutation and both parents need to carry the recessive gene. Be very cautious when a breeder is trying to sell you a rare white pitbull. Albinism comes with many health issues, including deafness or skin cancer.
Due to their pale coat, they must be protected from direct sunlight at all times using either bodysuits or sunscreen. White patches around the eyes or nose can occur due to a lack of pigmentation. Pit Bulls or any other breed with dominant white coats can develop light eyes or a pinkish nose. Recommended Reading: Traits of the Rottweiler-Husky mix. Dogs with blue eyes are not necessarily doomed to develop any vision-related issues.
It largely depends on the specific reason your dog might have this eye color. Pit Bulls are not among the breeds that carry this breed-specific gene, meaning that they probably will develop health problems later on. If you find a responsible breeder that has legitimate puppies with blue eyes, there is probably nothing you need to worry about as the color will start transforming at the age of 4 months.
They carry a breed-specific gene that allows them to have bright blue eyes without any related health issues. Bluish eyes can also occur in Weimaraners and Amstaffs. Eye, coat, nose and skin color of any mammal is determined by the production of melanin. Lack of pigmentation can lead to blue eyes, a white coat and a pink nose. Blue-eyed puppies are very common among many breeds and adorable to look at. Hey Danielle! I never thought about melanin as being the main factor in eye, coat, nose, and skin color.
Very interesting! Hi Jason, there are certainly experiments related to genetic engineering which could definitely influence the colors and there have been studies like this or this that touch on the melanin subject. However, if you mean through dietary changes, supplements, etc. If a dog carries a certain gene for a coat color, hereditary rules apply which can tip the scale in favour of a certain color through selective breeding.
There is a very sweet dog up for adoption at a nearby shelter. She looks very much like a pitbull, she is grey and has some white on her forehead. She has one brown eye and one bright blue eye, it is pretty, but I don't know why it is like that. I wonder if there is a test for the merle gene? However, with rescues I'd view this more as a fun way of getting to know more about your dog. If you're interested in adopting, go for it if the dog fits your lifestyle and personality.
Somebody has to adopt this poor soul and most health issues will surface once the dog is an adult not always though. A lot of good information. We are looking to buy a pit bull puppy merle color but it has one eye blue and one eye brown. I'd stay away from these breeders and instead buy from a reputable breeder that only uses healthy purebreds for his breeding program.
If you follow the guidelines in my breeder question post, I'm sure this breeder would be eliminated with these questions anyway. Feel free to check out this post if adoption is an option, many beautiful mixed breeds available there :.

Jason Monday 1st of February Danielle Monday 1st of February Danielle Thursday 27th of August Hi Trinity, there are DNA tests that might provide clues as to which breeds were involved and from that, you know if the merle gene is even a possibility.
