Why Is My Dog Losing Hair? The Short Answer

There are a number of common general reasons why certain dogs lose their fur, including allergies, parasites, hormonal imbalances, infections and stress. While it is normal to lose hair from time to time, particularly during the spring and autumn shedding season of double-coated animals, if you are wondering: why is my dog losing hair in patches, unevenly, or with itching and redness, then it’s time to investigate further. The distribution, extent and rate of hair loss all provide useful information on the cause of the loss.

There are certain medical causes of hair loss that are common in dogs. Certain medical causes of hair loss are widespread, for dogs.

The most common conditions veterinarians see when clients ask, “Why is my dog losing hair?” are:

1. Allergies

One of the most frequent responses to the question of why is a dog losing hair is that they are allergic to something, such as the food they are eating or a flea or environmental allergens such as pollen and dust mites. Itching is a very common symptom of an allergy that will cause a dog to scratch and lick in excessive amounts, resulting in hair loss on the affected area.

2. Fleas and other parasites

One of the common reasons given when owners ask why is my dog losing hair is the fleas, particularly around the tail, groin and back legs. There are dogs that get a reaction from a flea bite, leading to flea allergy dermatitis: so severe that they become itchy and start losing hair from just a single bite. Other causes to consider are parasites such as mange caused by mites.

3. Hormonal Imbalances

For middle age and senior dogs, there are answers for why is my dog losing hair, such as hypothyroidism and Cushing’s disease. Usually, this is a symmetrical process of hair loss and does not cause itching (unlike allergic causes of hair loss).

4. Fungal or Bacterial Infections

Although the name suggests otherwise, ringworm is a fungal infection and one of the most common causes of dog hair loss and is the cause that many owners ask why is my dog losing hair in circular crusty patches. Patches of hair loss may also result from bacterial skin infections, which may be accompanied by an odor, redness or pus-filled bumps.

5. Stress or Anxiety

One of the reasons why is my dog losing hair is a chronic stress and anxiety. Stress can cause some dogs to lick or chew in certain areas to the extent of causing bald spots, especially on legs or paws.

6. Poor Nutrition

Sometimes, an unbalanced or poor diet is responsible for the loss of hair in dogs. A lack of needed fatty acids, protein or some vitamins can cause this, as the coat strength will be compromised resulting in shedding or thinning fur.

7. Autoimmune Conditions

Rarerly, autoimmune diseases also can contribute to the reasons why is my dog losing hair, especially if the hair loss is accompanied with skin lesions, crusting or changes to pigmentation.

Non-Medical Causes of Hair Loss

Sometimes, the loss of hair is not related to a health issue. Let’s try considering these more benign explanations first:

• Shedding: Some breeds shed a lot in the spring and fall due to the changing weather.
• Normal ageing: As dogs get older their coats may naturally become thinner, which is not a disease.
• Rubbing or friction: Rubbing or friction can cause the loss of hair on the elbows or hips.
• Recent grooming or clipping: This is a very short cut, and can sometimes appear to be hair loss until it grows back in.

Even when all these simpler causes have been eliminated, it may still seem logical to seek veterinary advice if you’re still wondering why is my dog losing hair?

Symptoms That Can Accompany Hair Loss

Do not solely concentrate on the loss of the fur when asking the question why is my dog losing hair. Look for the following symptoms to help your vet determine the cause:

• Rusting, scabbing or crusting of the skin
• Excessive scratching, licking or chewing
• Smelly skin or coat
• Any changes in skin color or thickening
• Lethargy or weight gain, that may indicate hormonal issues
• Fleas or flea dirt are visible, or mites can be seen

When you notice the symptoms of losing hair along with several of these, it is crucial that you have your dog checked by a vetenarian as soon as possible as to why is my dog losing hair?

1. Examination of the hair loss pattern, location and physical examination of the skin.

3. Culture of fungus: examination for ringworm or other fungal diseases.
