Dogs usually lose hair because they scratch an itch when they lose some hair.
You might wonder what may be causing excessive hair loss without any signs of itching if they keep losing excessive amounts of hair.
Remember, shedding is completely normal for dogs before we dive deeper into the subject.
Because of their long or thick hair, some dog breeds shed more than others.
Thus, we will refer to “hair loss” in this article as excessive hair loss resulting in visible thinning or balding.

Why do dogs lose hair without itching or scratching?
There are many reasons that dogs (and humans) lose their hair, and it is commonly referred to as alopecia.
It is possible for dogs to develop alopecia without itching for the following reasons:
Inflammation and shrinkage of the thyroid gland are symptoms of hypothyroidism.
There is no itching or inflammation of the skin associated with this disease, and it often results in dogs losing their hair.
Hypothyroidism-induced bald spots on dogs are symmetrical on each side, a unique characteristic of hair loss in dogs.
You can also check your dog for hypothyroidism by looking for weight gain, thickening of the skin under the armpits, and a tendency to get cold easily.
Hereditary hair loss
The majority of dog hair loss is accompanied by itching, but alopecia without itching is often hereditary. Alopecia color dilution (CDA) is a genetic condition that causes hair thinning and patchy hair loss in dogs.
In most cases, hair loss does not itch, but secondary skin infections may cause itching. A dull coat, graying hair, and melanoma are also symptoms of hereditary hair loss.
Hair loss may occur when your dog keeps pressing or weighing on the same spot.
Pressure sores most commonly occur on a dog’s elbows, hips, or sides when he is old or sick and immobile.
They can be moved so they don’t always lean in the same direction.
Hair loss can also be caused by constant pressure from a collar.
If your dog’s collar area has thinning hair, take it off every so often and don’t reattach it.
In dogs with skin cancer, hair is often lost in the area of the tumor lump, and this hair loss does not itch. Symptoms such as lumps that might be ulcerated should also be noted.
When clipping a dog’s hair, it may grow back thin and patchy, especially if the dog has a dense double coat. It might appear that they have bald patches, but their coat should grow back over time. You can request treatments from the vet if it doesn’t.
How are these causes diagnosed?
When you bring your dog to the vet for hair loss, the vet will take a few steps to diagnose it.
1. Examine the pattern of hair loss
Veterinary professionals can get a good idea of what’s causing the problem by looking at the pattern. The loss of hair in patches is most often caused by ringworm or bacterial infection, while the loss of hair in symmetrical patterns may be the result of thyroid or adrenal gland disorder.
2. Blood testing
We will take a blood sample from your dog and test it to determine if they have diabetes, thyroid disease, or immune system conditions.
Cancer and skin tumors can be ruled out with a biopsy.
4. Skin smears and scraping
It will determine whether the skin is infected with bacteria, yeast, or parasites. It is also possible to test for the presence of ringworm by using a luminescence test.
5. Allergy testing
If your dog has allergies, the veterinarian will check them.
Could a vitamin deficiency be the cause?
Diet plays a huge role in everything, as you probably already know. Humans and dogs alike will suffer from physical and mental problems as a result of what they eat.
The following vitamins are essential for dog hair health:
- Omega-3 fatty acids. You can use them to moisturize your dog’s skin and hair.
- Vitamin E. To prevent dry skin.
- Vitamin A. It supports the growth of hair cells and promotes sebum production.
- Biotin. Fatty acids are also produced for the strengthening of hair.
A lack of these vitamins might contribute to your dog’s hair loss. It doesn’t mean you should give your dog three servings of these vitamins at once. It’s important to keep in mind that too much of them can also be problematic.
Analyze the nutrients in your dog’s usual meal to determine what they are lacking. Supplements or foods can be used to replenish the vitamins you are lacking. There are also some vitamins that can be applied topically, such as vitamin E.
Why else do dogs lose their hair?
In addition to losing hair when they have an itch, dogs often suffer from lice infestations. The following are some of the most common causes of hair loss in dogs.
In dogs with itching and hair loss, allergies are the most common cause. Allergies may be caused by certain foods, fleas, pollen, or simple seasonal changes.
2. Parasites or Infections
Parasites are another common cause of hair loss and itching. When your dog is infested with parasites or pests like ringworms, they tend to scratch and chew on its skin. The constant tugging of the skin will ultimately result in hair loss.
3. Cushing’s Disease
Hyperadrenocorticism, commonly known as Cushing’s disease, is characterized by excessive cortisol levels. The excessive amount of cortisol in the body can lead to skin changes, including hair loss and redness.
What are the most common areas on a dog for hair loss?
- Around the eyes and mouth
- On the head,
- and body.
The ears, chest, lower neck, and belly are the most commonly affected areas if the hair loss is genetic.
Which dog breeds are more prone to hair loss?
Alopecia is more prevalent in the following breeds of dogs:
- Bernese mountain dogs
- Chow Chows
- Great Danes
- Yorkshire terriers
The best treatment for dog hair loss
Since dog hair loss is caused by a variety of things, the treatment will also differ depending on what’s causing it.
- For dog hair loss induced by bacterial infections
Managing infections is of course the first step when it comes to infections. The infection can be treated with either oral or topical antibiotics.
- For dog hair loss induced by fungal infections
Antifungals can also be purchased orally or topically if the problem is a fungal infection.
- For dog hair loss induced by allergies
Several methods can be used to treat allergy-related hair loss. In order to manage environmental allergies (atopy), immunosuppressive or anticytokine drugs can be used. Desensitization to allergies can also be achieved through immunotherapy. A hypoallergenic diet might be recommended by the veterinarian if the dog has a food allergy.
- For dog hair loss induced by thyroid diseases
Thyroid disease can cause hair loss that requires more complex treatment. In most cases, hormone therapy and thyroid medications are used to treat the disease.
- For dog hair loss induced by skin cancer
In addition, if your dog is losing hair due to skin cancer or a tumor, the tumor must be removed through surgery to stop hair loss.
In the end, the cause of hair loss is what you need to treat when dealing with hair loss. There is no medication that can target hair loss itself without treating the cause. In the case of hereditary hair loss, there is no treatment available.
Can you use over-the-counter medications to treat dog hair loss?
Dogs can take over-the-counter medications to treat hair loss. Ensure you read the labels carefully and ask your vet to make sure you’re choosing the right medication for your dog.
If allergy-related hair loss is affecting you, you can buy antihistamines such as Benadryl or Claritin. Over-the-counter antibiotic ointments like Neosporin or antifungal sprays are available.
Effective home remedies for dog hair loss
1. Use a moisturizing shampoo
Managing your dog’s hair loss begins with his most basic hair care: his shampoo. Among the factors that contribute to hair loss in dogs is dry skin and hair. Invest in a dog shampoo that is extra moisturizing-or better yet, one that has been specially formulated to prevent hair loss.
2. Brush your dog’s hair
In order to keep it simple, your dog’s hair should be brushed on a regular basis. Keeping their skin and fur naturally moisturized is made easier by spreading out their natural skin oil.
3. Use diluted apple cider vinegar
There are plenty of health and beauty benefits associated with apple cider vinegar or ACV. It’s also very easy to use, just dilute organic ACV with water to make a 1:1 blend and spray it on your skin or hair. Your dog’s coat should be sprayed with the solution every day. Because ACV is too harsh, you should never apply it undiluted to their skin.
Aside from lemon juice, olive oil, aloe vera, and flaxseed oil, other home remedies are often used to treat hair loss.
