Lab dogs with a black coat are a rare breed, making up only about 10% of the Labrador Retriever population.
Their black coat is not a result of a specific genetic mutation, but rather a dominant gene that masks the yellow or chocolate colors of the parent dogs.
Lab dogs with a black coat are just as friendly and outgoing as their yellow or chocolate counterparts, known for their gentle and even-tempered nature.
In fact, black Labradors are often sought after by families with children due to their calm and patient demeanor.

Labrador Retriever Genetics
Labrador Retrievers have four colors: black, yellow, chocolate, and all colors, which are determined by a unique series of genes.
The genetics of Lab coat color is quite interesting, and understanding it can be helpful for dog owners and breeders alike.
Black Labradors have a dominant black gene, the B locus, which gives them their signature black color.
A different take: What Colors Are Labrador Retrievers
The B locus gene is responsible for the absence of other colors in black Labs, as it does not allow the expression of different fur colors.
The eumelanin gene is a type of melanin that can be found in Labrador Retrievers and other dogs, and it's responsible for producing black, brown, and yellow coat colors.
A dog with two eumelanin genes will produce a black coat, while a dog that has one eumelanin gene and one that is a non-eumelanin gene will have a chocolate coat color.
The eumelanin gene is inherited from the sire and dam and is passed on to puppies.
Labradors with the silver coat color have the same genetic makeup as the black Labradors.
The genetic makeup of Labradors can be linked to specific health issues, and understanding it can help breeders and owners make informed decisions.
The E locus gene produces eumelanin, the pigment that gives black Labs the dark black color, and it's another dominant gene that's responsible for the expression of black fur.
The B Locus gene is a dominant gene that, if the dog has one copy of the gene, it will express black fur as a consequence.

The genetics of Labrador colors can help breeders and owners better predict their pups' color, and knowing what exact genes are responsible for coat color can help breeders avoid producing puppies with undesirable colors.
Labradors have a gene that we call A locus, which helps determine the intensity of the coat color, regardless of the other three mentioned genes.
The A locus is responsible for the range of colors seen in Labs, from light cream to deep chocolate.
The eumelanin gene is the most important gene that affects coat color in Labradors.

The Labrador Retriever Colors
The Labrador Retriever breed comes in four colors: black, yellow, chocolate, and all colors. These colors are determined by a unique series of genes the dog carries.
The black Labrador has a dominant black gene, the B locus, which gives them their signature black color. The B locus is a dominant gene, meaning if the dog has one copy of the gene, it will express black fur as a consequence.
The chocolate Labrador has the b locus gene responsible for the rich chocolate color. Both parents must carry the chocolate coat gene to make a chocolate-colored puppy, as it is caused by a recessive gene.
The yellow Labrador carries an E locus gene that makes their coat yellow. The E locus produces eumelanin, the pigment that gives yellow Labs their coat color.
The A locus gene helps determine the intensity of the coat color, regardless of the other three mentioned genes. This gene is responsible for the range of colors seen in Labs, from light cream to deep chocolate.
The silver Labrador has the same genetic makeup as the black Labrador, but with a charcoal grey coat color. The charcoal Labrador is a result of a recessive gene in the Labrador breed.
The red fox Labrador variety is a result of a recessive gene, and their coat color can range from pale cream to a deep golden yellow. Their coat color is just one of many attractive qualities that make them a popular choice for pet owners.
The American Kennel Club (AKC) recognizes three distinct color variations in the Labrador breed: black, yellow, and chocolate. The black Labrador is generally the most common color variety, and the black Lab is the only type of Lab that can have a dark nose (black) according to the breed standard.

Labrador Care and Health
Labradors are high-energy dogs that need several hours of exercise daily, with activities like running, swimming, and retrieving being ideal. They can easily overheat in hot conditions, so swimming is a great option.
Their huge appetite can lead to overeating and obesity, so monitoring their food intake is crucial. DNA studies have shown that many Labs carry a mutation in the POMC gene that regulates hunger.
A thick coat that sheds profusely at times requires daily brushing during shedding seasons, but for the rest of the time, coat care is minimal.
Labrador Health Implications
Labradors with a yellow coat color are more prone to certain ear infections and illnesses.
Routine vet visits and early diagnosis are crucial for catching and treating any health problems that might arise in Labs.
The black coat color is linked to an elevated risk of some types of skin cancer in Labs.
A healthy diet and regular exercise can help minimize the risks associated with Labrador coat color.
With proper care and attention, the dangers associated with Labrador coat color can be minimized.
Understanding the risks associated with each color can help future dog owners make informed decisions when selecting a Lab puppy.
Care and Upkeep
Labrador Retrievers need several hours of exercise daily, which can be achieved through activities like running, swimming, and retrieving.
Their high energy levels mean they can overheat in hot conditions, so it's essential to keep them cool and engaged in swimming or other low-impact activities.
The breed's strength can be a challenge for children and the elderly to handle, so it's best to use a collar rather than a harness to maintain control.
A Labrador's huge appetite can lead to overeating and obesity, so monitoring their food intake is crucial.
DNA studies have shown that many Labs carry a mutation in the POMC gene, which regulates hunger and increases the risk of overeating.
Labradors are susceptible to canine hip dysplasia, so it's essential to feed them a large-breed puppy food to slow down their growth and reduce the risk of dysplasia.
Their thick coat is fairly waterproof, but it can shed profusely during spring and fall, requiring daily brushing to prevent matting.
For the rest of the year, a quick brushing once or twice a week is sufficient to keep their coat in good condition.
An occasional bath is all that's needed to keep your Labrador clean and healthy.
