There are many common skin diseases in dogs, including bacterial skin diseases, fungal skin diseases, allergic skin diseases, parasitic skin diseases, endocrine skin diseases, etc. Let’s take a look at it in detail below.

Bacterial skin disease, also known as pyoderma, refers to a skin disease in which bacteria proliferate abnormally on the skin surface, forming pustules or purulent exudates. Bacterial skin diseases can occur due to anything that changes the microenvironment of the skin.

The lesions present symptoms such as mild itching, erythema, papules, crusts, lichenification, pigmentation, and sebaceous leakage. Dermatophytes commonly have round or non-circular and non-characteristic areas of hair loss. The lesions may produce scales, erythema, or scabs formed by scratching. The coat is prone to falling off and breaking, and collar-type lesions may occur. Hair loss is common on the face, ear wings, limbs and tail.

Allergic skin diseases have itching as the main symptom. Common ones include allergic dermatitis and atopic dermatitis caused by flea bites. Common parasitic skin diseases are canine scabies, hair follicles, fleas, lice, etc. Canine scabies mites parasitize in the epidermis. The lesions caused by hair loss, scales and scabs first appear on the face, around the eye sockets, on the edge of the ear wings and elbows, and then spread to the whole body. The symptoms of itching are extremely obvious. It is more common in puppies and stray dogs. Trichocystis is a common external parasite of the skin. It is generally believed that under various conditions such as host T cell deficiency, abnormal immune function, malnutrition, and excessive growth, Trichocystis can proliferate abnormally and form skin lesions.

Clinical lesions mainly include hair loss, scales or scabs, which appear around the orbits, lips, and locally between the fingers (toes). The lesions will gradually spread to the whole body and cause symptoms such as secondary infection. Typical symptoms of endocrine dermatoses include bilateral symmetrical hair loss, skin pigmentation, and dry coat that easily falls off. Common endocrine skin diseases include: hyperadrenalism, hypothyroidism, growth hormone deficiency, sex hormone imbalance, etc.

Clinically, skin diseases cannot be diagnosed with the naked eye alone, and many laboratory tests are required to assist diagnosis. Common tests include: skin scraping examination, coat examination, direct smear and cytology examination, pressed smear and tape adhesion examination, direct microscopy with potassium hydroxide, bacterial culture and sensitivity test, fungal culture, Wood's Ultraviolet lamp examination, serum detection of endocrine hormone levels, allergen intradermal test, skin tissue pathology examination, etc.

After the doctor makes a professional diagnosis, he will provide a professional and comprehensive treatment plan. Treatment drugs are usually oral and topical drugs, including oral antibiotics, antifungal drugs, antiparasitic drugs, immunosuppressants, skin nutrition drugs, etc. Topical applications include skin drops, sprays, lotions, etc. Topical drugs are often used for single local lesions, while the treatment period for systemic skin diseases is longer and prone to recurrence.The daily living environment needs to be kept clean, and regular bathing and insect repellent are required.
