The skin is the largest organ in a dog’s body. Together, the skin and hair make up the dog’s coat. People say that a dog’s coat shows how healthy it is, and, indeed, you can see by the coat condition if the dog is glowing with good health or is starting to have health issues.
What Kind Of Diseases Causes A Dog To Lose Hair?
Alopecia, or hair loss, can be induced by several illnesses, including skin infections, allergies, and endocrine abnormalities. It is a prevalent condition among dogs. Any dog breed or age may have hair loss. You must visit a veterinarian as quickly as possible if you observe hair loss because the primary issue can range from mild to severe.
Symptoms Of Hair Loss In Dogs
Dog hair loss can happen at any age, in any breed, and anywhere on the body. It is often a visible condition. Depending on the underlying reason, many patterns and symptoms may appear:
- A general hair thinning
- Loss of hair near the mouth and eyes
- Complete hair loss in patches
- Hair loss in the exact location on both sides of the body in symmetrical patterns
- Bad odor
- Dark grey or black skin with thinning hair
- Dry, scaly skin in the hair loss area
- Skin that is red and swollen around the hair loss area
- Bleeding or moisture oozing from the scalp’s hair loss area (typically a secondary condition)
Causes Of Hair Loss In Dogs
Extreme dog hair loss can occasionally be regular shedding. When the individual hairs get old or damaged, or seasonally when the weather gets warm, dogs start to lose their fur. All year long, many dogs shed.
Breeds with thick winter undercoats shed in the spring include huskies and labradors. If you live in a temperate environment, seasonal shedding is frequently decreased. Brushing your dog two times a week will help remove and manage extra hair if the shedding is out of control.
Bacterial And Fungal Infections
Although yeast and bacteria are familiar occupants of canine skin, occasionally, they can develop out of control and cause an infection. On the skin, bacterial or fungal yeast infections can result in odor, redness, itching, and hair loss. Sometimes bacterial infections result in bumps that resemble pimples.
Ringworm, a fungus that results in hair loss and small patches of infection (no, it’s not a worm), can also affect dogs. Visit your veterinarian if you notice red, itchy, or scaly patches. Your veterinarian will perform a thorough examination, suggest some testing, and, if necessary, prescribe antibiotics or antifungals to treat the infection.
Manage And Other Parasites
Mange is a general name for mite-borne skin illnesses that are itchy and painful. Mites are tiny animals that reside on the skin’s surface or in hair follicles. They gnaw on or burrow into the skin, which results in hair loss and itching.
According to the Merck Veterinary Manual, some mites, such as the scabies mite, are very contagious to humans and other dogs. Although Demodex mites are not contagious, they still cause hair loss and might need to be treated.
One widespread cause of a dog losing hair is fleas. Dogs who have fleas may become so scratchy that some of their hair falls out. Mites and fleas are highly dangerous and may well have infected your home & other pets if they are found on your dog. Your veterinarian can recommend an antiparasitic drug and advise on getting rid of bugs from your home if you discover evidence of mites or fleas.
Like people, dogs can develop allergies; the most noticeable symptoms are itchy skin and hair loss. Environmental allergies to irritants like pollen, mold, dust mites, flea allergies, and food allergies are the most prevalent allergens in dogs. If your veterinarian detects allergies, they may advise flea management, itching relief medicine, avoiding allergens, or changing the pet’s diet to rule out food allergies.
Only after a food trial for a minimum of eight weeks can a person be diagnosed with a food allergy. Ensure your dog doesn’t consume any other food while participating in a limited-ingredient meal plan or therapeutic food trial recommended by your veterinarian.
One cookie or chicken nibble taken without permission can skew the findings. If the allergies are correctly treated and the underlying reason is identified, your dog’s hair should grow back, and the itching should go away.
Underlying Medical Conditions
If a dog is shedding hair all over his body, there may be an issue underneath the hood. In terms of size, the skin is the largest organ in the body and needs a lot of nutrients to keep healthy. An underlying medical problem may impact your dog’s hair and fur.
A dog may experience hair loss due to hormonal issues such as hypothyroidism, adrenal gland diseases, or growth hormone disorders. To identify the underlying reason for the hair loss, your veterinarian may advise laboratory testing and possible X-rays or ultrasound imaging.
Stress, poor diet, pregnancy, nursing, or any underlying medical condition can contribute to excessive shedding. Make a meeting with your veterinarian if you believe your dog is shedding more than usual or if you notice any bald patches on him. They will recommend a dog hair loss therapy based on your pet’s other medical requirements.
While a dog losing hair needs to see a veterinarian, his illness is frequently treatable with a straightforward diet modification or medication. Maintain consistent grooming and brushing so you can recognize problems at their earlier stages.
Diagnosis Of Hair Loss In Dogs
A veterinarian should check you’re pet if they see hair loss to identify the underlying reason and administer any necessary treatments. The diagnosis is made based on the beginning of symptoms, hair loss pattern, surrounding skin condition, or whether the animal is uncomfortable or unpleasant.
Hair Loss Pattern
Generalized hair loss may signify bacterial illness or management. Patches of hair loss may be a sign of mange, ringworm, bacterial infection, or mites. A flea allergy is frequently blamed for hair loss in the rump and tail base region. Environmental allergens can sometimes cause hair loss on the face and paws (atopy). A thyroid condition, an adrenal gland disease, or abnormal sex hormone levels may all be symptoms of symmetrical hair loss (endocrine disorders).
Blood tests can identify Cushing’s disease, diabetes mellitus, thyroid diseases, immune system disorders, and hormone abnormalities.
The veterinarian may send a sample of the afflicted region to the lab for diagnosis and treatment if skin cancer or a tumor is suspected or in chronic, unresponsive skin lesions. Skin impression smears can reveal the presence of bacteria, yeast, or inflammatory cells by pressing a microscope slide against the afflicted area and examining it.
Mange mites can be found by gently scraping the skin with a blade to collect hair follicles onto a slide.
Some ringworm species emit a bright green-yellow glow under UV light.
Allergen Elimination Tests
A food allergy may be discovered by feeding a hypoallergenic diet, treating fleas, or quitting using particular shampoos or medications. Skin and blood tests for allergies can help to reduce the number of potential environmental allergens.
Treatment Of Hair Loss In Dogs
Different therapies are available for dog hair loss, depending on the diagnosis.
- Oral or topical antibiotics are used to treat bacterial infections.
- Topical or oral antifungals can treat ringworm and yeast infections.
- To treat specific skin disorders, steroids may be necessary.
- Immunosuppressive or anti-cytokine medications may be required to treat environmental allergies (Atopy). The necessity for lifelong treatment is every day.
- Oral or injectable immunotherapy may be required for allergy desensitization.
- Behavioral drugs can be used to treat nervous licking or chewing.
- Mange can be treated with prescription shampoos or dips.
- Hypoallergenic diets can frequently stop hair loss caused by food allergies. It takes some time to identify dietary allergies. The vet will suggest a prescription or over-the-counter hypoallergenic food and review how to switch to the new diet properly.
- Hair loss brought on by flea allergy can be reversed with monthly flea prevention.
- In hormonal and endocrine abnormalities, thyroid medication and hormone therapy can stop hair loss.
- Pets with certain illnesses or a propensity for dry skin or skin infections may benefit from taking vitamin E, vitamin A, and fish oil supplements.
- You might need to use an Elizabethan collar (e-collar or cone) to stop your pet from licking or scratching the injured area while it heals.
- Skin cancer or tumor parts may need to be surgically removed. Your pet may require fixing or spaying if it has abnormal sex hormones.
