Dog Skin Disease 1: Parasitic Skin Disease

As the name suggests, this type of skin disease is a skin disease caused by parasite infection on the body surface. Parasites live in the dog's epidermis or hair follicles, causing severe itching and scratching.
After cleaning the skin and hair of the affected area, use a razor blade and vegetable oil to scrape off the skin flakes, and use pliers to pull out the hair from the affected area. After careful examination under a microscope to determine which type of external parasite the parasite belongs to, select the corresponding anthelmintic drug to kill it.
Demodex mites mostly infest the face around the eyes, around the mouth, and the palms of the limbs. Obvious clinical symptoms include hair loss and redness around the eyes and mouth. Once Demodex is diagnosed, it cannot be cured for life, and it is easy to relapse, but it can be suppressed with drugs. Dogs suffering from Demodex mites should not eat meaty foods with high fat content. Once eaten, dogs can easily relapse.

Scabies mites

Scale mites are mostly parasitic on the ears, back elbows of the limbs, face and chin. The early clinical symptoms are thickening of the ear source and rash on the affected area. As the condition worsens, hair loss will begin on the back elbows of the limbs, itching, and frequent scratching of the ears and limbs. When the infection finally develops into the whole body, if the coat is shaved, papule-like lesions will be found all over the body.

Treatment methods

When skin diseases caused by parasitic infections occur, you should be taken to the hospital to confirm the type of parasites infected, and use corresponding anthelmintic drugs based on the examination results. If the early symptoms are mild, you can use broad-spectrum dermatological spray after deworming to observe the development of the skin disease. If symptoms are severe or confirmed to be complicated by other infections, medications should be taken together.

Dog skin diseases 2: Bacterial and fungal skin diseases

The symptoms of these two skin diseases are similar, and the examination and diagnosis methods are similar, so they will be analyzed together. There is a certain amount of bacteria and fungi on the surface of the dog's body. When the dog is healthy, the skin has a complete skin barrier and has good resistance to fungi and bacteria, so it does not get sick. But once the skin barrier is damaged, or bacteria and fungi multiply on the body, the dog will be infected with skin diseases.

For this kind of skin disease, after the hair in the affected area is repaired, a clean slide can be used to press the affected area to collect the bacteria and fungi on the skin of the affected area. Put the stained slide directly under a microscope to observe what kind of bacterial infection is on the skin surface. There are certain flaws in the detection accuracy of this method. The best way is to collect the bacteria on the skin surface of the affected area and culture them. The diagnosis is then confirmed under a microscope. The diagnosis rate is high but the culture time is long.

After confirming which type of fungus or bacteria it is, you should shave the hair from the areas with skin disease to facilitate the application of medicine. More serious skin diseases need to be treated with oral antifungal or antibacterial anti-inflammatory drugs and medicated baths.

Dog Skin Disease 3: Nutrient Deficiency Skin Disease

Nutrition Deficiency Skin Disease is due to the daily growth of the skin.It is caused by nutritional deficiencies and is common in young dogs. When young dogs are bought back, some may be underweight, anemic and malnourished. In addition, young dogs grow and develop rapidly and have high nutritional needs, which can easily lead to insufficient daily nutritional intake.
This type of skin disease generally presents with dry and brittle hair, red skin, rashes on the skin surface, and increased dandruff. Clean the hair in serious areas, clean and disinfect the lesions, and then use a broad-spectrum dermatological spray. It is also necessary to supplement skin nutrition, such as vitamin B, vitamin E, selenium, etc.

Dog Skin Disease 4: Atopic Dermatitis

Atopic dermatitis is a skin disease caused by allergies due to disorders of the dog's own immune regulation. It is caused by the dog's own allergy to a certain ingredient in the food or a certain substance in the environment. The clinical manifestations are similar to bacterial and fungal infections.
The diagnosis of atopic dermatitis is more complicated. Clinically, it is often diagnosed as atopic dermatitis after other types of skin diseases have been ruled out. Allergen testing can also be used to predict whether a dog is atopic. dermatitis.
The first priority in treating dogs with atopic dermatitis is to find the allergen. After the allergen is diagnosed, the dog should avoid contact with the allergen. Then take anti-allergy medications and antibiotics.
