Like people, dandruff develops in dogs because flakes of dead skin cells begin to cling to the hair and other areas where they settle. While dandruff typically affects the head in humans, it more frequently affects the back and tail of dogs. Your dog may have dry white “flakes” on his coat or in his favorite hangout spots. 

Additionally, if you give him a good scratch, you may observe that his skin is flaky and dry. Dandruff is referred to as seborrheic dermatitis. Sebaceous glands on your dog’s skin create sebum, an oil that keeps the skin supple and moisturized. This is a skin imbalance resulting from these glands overproducing sebum. 

There are two kinds of seborrheic dermatitis: dry and oily seborrhea. Dogs may possess a mix of the two. In this article, you’ll learn how to treat dandruff and when to seek treatment from a vet. Get ready to stop your indoor snowing problem! 

Dry Skin and Genetics

Because the air is drier than usual in the winter, dogs may feel dry skin, similar to people. Heating using forced air may exacerbate the issue. If you only notice dog dandruff during the winter, the dryness of the air may be to blame. You can get a humidifier for the room where your dog spends the most amount of time, and that’ll help prevent the issue. Fish oil supplements can be helpful. 

Fish oil is excellent for skin and fur health and can help skin stay hydrated. Using a gentler shampoo and fewer baths can also help dogs keep their natural skin moisture. Some dogs are more likely to have dandruff because of a genetic disorder, such as primary seborrhea, which causes it to be a primary problem. Dogs more likely to have primary seborrhea are:

Allergies

Dandruff in dogs can be brought on by allergies, including those to the environment and dog food. Allergies in dogs typically manifest as skin issues known as allergic dermatitis. Dogs with allergies frequently have dry, flaky skin and may chew or lick themselves excessively. 

Your veterinarian may suggest efficient flea management, a trial of a specific hypoallergenic diet, or allergy testing to find out exactly what your pup is allergic to. You can take notes on when your dog has these symptoms. Make a note of shampoos and what they may be around outside, and keeping a food diary may also help. 

If you have trouble figuring out if your dog has a food allergy or is just suffering from seasonal allergies, your vet can be helpful. Always check with a vet before you give your dog medications like Benedryl to relieve symptoms like itching. Keep in mind dry skin in these cases may not entirely be cured, but it can be managed by limiting their exposure to the causes of the allergies. 

Ringworms

Unfortunately, some canines with ringworm are asymptomatic—that is, they don’t exhibit any outward symptoms of the illness. Due to how quickly dog ringworm spreads, this could be problematic. Once you see any ringworm signs in your dog, you must visit your veterinarian. The most typical symptoms of ringworm in dogs include bald patches, red, irritated skin, and flakes that resemble dandruff in your dog’s deep coat.

Regardless of how serious it is, dog ringworm should always be treated immediately due to its contagious nature. There are numerous approaches to treating dog ringworm. Combining topical and oral therapies is the most typical course of treatment for it. Dogs with ringworm can benefit from topical medicine, which involves applying topical antifungal drugs directly to the affected area. 

Antifungal medications are taken orally to treat the infection. Additionally, your veterinarian can suggest coat trimming or trimming your dog’s fur around any location that has the fungus. This will help stop it from spreading and allow the active ingredients in the shampoo or cream to work better.

Hormonal Imbalances

Hormonal imbalances can cause hair loss in dogs

Numerous internal and external variables contribute to having healthy skin and a regular hair coat. Several glands in the body release hormones into the bloodstream. The endocrine system refers to these glands and the hormones they produce. The production of healthy skin and hair coats, as well as the control of other bodily processes, depends on the hormones. 

Failure of an endocrine organ to release the correct quantity of its hormone is a common cause of skin disease. Typically, this causes hair loss and poor skin quality. Other minor changes might also be noticed in the pet’s past or discovered through a physical examination based on the hormone in question. This knowledge could direct the tests toward the organ that is most likely to be implicated. The prognosis for hormonal abnormalities is typically good. Some are surgically cured, while others require lifetime drug treatment. Some examples of causes are:

  • Hypothyroidism
  • Cushing’s Disease
  • Sex Hormone Imbalance
  • Seasonal Flank Alopecia

Nutritional Deficiencies

Nutritional deficiencies can cause dandruff in dogs

Sometimes nutritional deficiencies can cause dandruff—for example, omega-3. The truth is that many of the nutrients your dog needs are lost during cooking, despite claims to the contrary made by commercial dog food manufacturers. High temperatures render many nutrients, particularly fatty acids, useless when making kibble. 

Pet food producers add synthetic vitamins and minerals to the kibble to compensate for the lost nutrients, which can only help so much. Even dogs on raw food diets may not always be safe. A raw diet must be carefully balanced to provide your dog with all the nutrients they require. Even if a raw diet might be more nutritionally complete than a commercial diet, that doesn’t mean it is infallibly superior. 

Many dogs on raw diets require nutritional supplements. The next step is to look for a nutritional deficiency if no diseases are causing your dog’s flaky skin, as a diet low in omega-3 essential fatty acids is the most prevalent contributor to dry, flaky skin in animals. Dogs must consume their recommended omega-3 fatty acids to maintain good health. There are several fish oil supplements available that can help.

Conclusion 

It’s normal for dogs to experience dandruff at one point or another, and it can often easily be treated if it’s not a common issue with your pup. Often a dandruff shampoo for dogs, fish oil supplements, and washing them less frequently can help. A comb for fleas may also help to remove dandruff more effectively. 

Aside from dry skin, other skin issues may require a lot more work to treat. Ringworms are extremely hard to stop from spreading, and hormonal imbalances can be tricky at first. Hopefully, your pup’s skin is flaking because of low humidity, but if that’s not the case, a vet will better be able to fix the problem. 

Once you figure out the cause of dandruff, you’ll better understand how to treat and hopefully prevent the problem from arising again. Check out the posts below to find more helpful information on your pup, and share this article if you know a dog owner whose dog makes it snow all the time!
