Why is my dog’s skin going black?
Hyperpigmentation is a darkening and thickening of the skin seen in dogs. It is not a specific disease but a reaction of a dog’s body to certain conditions. Hyperpigmentation appears as light-brown-to-black, velvety, rough areas of thickened, often hairless skin.
Why does my dog’s fur turn brown?
Brown fur staining is primarily caused by an infection with the yeast Malassezia. This is the yeast that is responsible for skin and ear infections in dogs. It is possible that your dog has both conditions.
As most puppies grow into adulthood, the changes in their coats are noticeable but not dramatic. That’s not the case with certain breeds, in which the changes as they develop mature coats are truly stunning. … Only a black and white Shih Tzu will keep the coat color he was born with. With the rest, it depends on genes.

Puppies often do not gain their adult coloration until they reach maturity, so if you’re adopting a puppy, you may notice some changes to its coloring as it nears adulthood. Also, dogs’ coats tend to lighten as they age, so mature and elder dogs tend to have lighter colored coats than they did as young dogs.
There is a specific gene that can make a puppy black, no matter what his parents’ colors are, and it happens to be a dominant gene. So if both parents are light-colored but they both carry the dominant black gene, chances are good that one or more of the puppies will be black or display black markings.
When a black puppy changes colors, it’s much more likely that they become lighter with age, rather than their coat faded to a light brown like the Soft Coated Wheaten Terrier. It’s not something that should be expected with all black puppies, but is common with certain breeds and mixes due to their genetics.
During winter months, most dogs’ coats will darken again due to limited sun exposure. Many professional dog grooming products offer detanglers that also contain sunscreen for fur, which will protect fur from damaging sunrays.
The main symptom of vitiligo is pigment loss in skin and fur. In some dogs, their entire body will be depigmented. In others, only certain spots will be affected (like the white patches around Rowdy’s eyes).
When dogs breed, the mother and father each randomly contribute one allele from each locus, giving each allele a 50% chance of being passed on to the pups. One of the alleles at each locus is dominant and determines the traits, like coat color, portrayed in the dog.
The easiest way to predict what color the puppy will eventually be is to look at the roots of the hair. Oftentimes, brown brindle puppies will end up being more gold as an adult, however, that is not always the case. Look at the tips of the hair.
Like humans, dogs tend to go gray as part of their natural aging process. And just like us, as dogs get older, the pigment cells responsible for color (specifically, melanin) stop being produced; this causes the strands to come out at a lighter shade, like gray or white.
Some poodles that are born a darker shade may eventually clear to an apricot shade by the time they are two years old. The coat of black poodle puppies may clear to silver or blue by the age of two. Dark brown poodles may change to a café au lait shade by the age of two.
Silver – A true silver Poodle is born black and clears by the age of 2. However, you will know a true silver by the age of 6 weeks, when the face and paws clear and the rest of the coat will follow in suit over the next year or two. Silvers will have black points and dark brown eyes.
It is also worth mentioning that you may find gray Goldendoodles. Well, these are still black Goldendoodles. Sometimes the black coats of Goldendoodle puppies tend to turn to gray when they are fully grown.

Black Dog Poop: What It Means For Your Pet
Cats and dogs produce a pigment called melanin (the same one humans have), which helps to determine the color in their hair and skin. There are two main types of melanin that the body can make: one is called ‘eumelanin,’ that results in a very dark black color and the other is called ‘pheomelanin,’ which has more of a reddish-brown color when produced by dogs and cats. For dogs and cats, the color of their hair coat is decided mostly by their genetics which result in variations in eumelanin and pheomelanin. However, in some cases, diet can also play a role.
Two amino acids, called tyrosine and phenylalanine, are important in making melanin (as a reminder, amino acids are the building blocks of protein). Dogs and cats must meet their needs for essential amino acids through their diet. Tyrosine can be made from phenylalanine, so diets need to either include enough phenylalanine and tyrosine or enough phenylalanine to meet the needs for both of these important amino acids. If there is not enough phenylalanine or tyrosine in the body to make the darker black pigment, eumelanin, then the pet will make the reddish-brown pigment, pheomelanin, instead, which requires less of these amino acids. Though research studies have determined how much phenylalanine and tyrosine are needed for optimal growth and general health in cats and dogs, pets with mostly black hair coats may have even higher requirements in their diet to produce enough eumelanin to make a darker black coat. Most pet foods have phenylalanine/tyrosine levels that are high enough to meet these needs.
If your cat or dog has a black hair coat that starts to appear more red, especially after a change in diet, we recommend talking with your veterinarian to discuss whether diet may play a role for your pet. The first step may be gathering more information: you should tell your veterinarian everything you feed your pet. If you’re feeding a lot of treats or table food, or an unbalanced home-prepared diet, the overall diet could be deficient in amino acids and other key nutrients. Your veterinarian may call the pet food company to determine how much tyrosine and phenylalanine is in the diet, and how much your pet is getting based on how much of the diet they eat every day (this is also a great example of why pets who need to lose weight should have a specially formulated diet and not just reduce the amount of a maintenance food – you may be cutting back calories, but you may also be cutting back nutrients, too!). Your veterinarian may also recommend testing the amino acid levels in your pet’s blood. Based on all this information, your veterinarian may recommend a change in diet first to see if that changes their coat color back to a darker black. If your pet is on a special diet or sensitive to dietary changes, your veterinarian may also consider a trial of tyrosine and/or phenylalanine supplementation with a product that has independent quality control testing. If changing the diet or supplementation don’t seem to address their hair coat color, then your veterinarian may recommend other testing for possible medical conditions if diet is not the underlying reason. Most importantly, make sure you talk with your veterinarian about your pet’s diet to ensure it’s optimal for their lifestage, health, and individual needs. If your pet has many medical conditions that require unique dietary modifications, you might consider working with a Board Certified Veterinary Nutritionist.
