Contact dermatitis

This is a skin inflammation caused by physical and chemical factors in the environment. The dog's skin, especially the abdominal skin, often comes into contact with the ground because of its sparse coat. It is more susceptible to irritation and corrosion from grass, concrete, asphalt, plastic, flooring and residual chemicals on the surface, such as pesticides and disinfectants. Skin inflammation is mostly caused by direct irritation or allergic reactions.

Clinical manifestations are often actual redness, peeling, scabs, tissue exudation and secondary infection in the abdomen, thighs, chest and other parts of the body. Due to dog bites, this inflammation can also be seen in the dog's feet and perineum.

Diagnosis

Mainly based on clinical symptoms and medical history.

The goals of treatment are to reduce contact irritation, control infection, and promote healing.

① Eliminate environmental pathogenic factors, such as chemical agents, cement floors, grass, etc. that come into contact with dogs.

② The wound can be cleaned with mucosal disinfectants, such as Reifonol, and then corticosteroid ointment can be used, or antibiotics can be used together; in more severe cases, cortisone chloride can be used.

③ For severe inflammation in a large area, corticosteroids and antibiotics should be taken at the same time. Pekingese

Abrasion

Excessive moisture on the skin surface will affect normal epidermal keratinization, reduce the resistance of the skin's natural barrier, and make it susceptible to damage and infection. When accompanied by a certain degree of abrasion , this type of wet dermatitis is intertrigo, which mainly occurs in dog skin folds.

Early signs of inflammation are redness, swelling, and pain. If not detected and treated in time, tissue exudation and secondary infection often aggravate inflammation, and even cause odor and ulcers.

Treatment

The main purpose is to reduce humidity, reduce friction, and control infection.

① Keep the skin clean and dry.

② Apply corticosteroids to the affected area every day—antibiotic preparations or gentian violet.

③ In chronic cases, 1% silver nitrate cautery or complete skinfold excision can be used.

④ Wipe the fence between the toes and cut off the long hair between the toes to facilitate ventilation and cleaning. On rainy days, the contaminated debris between the toes should be washed away, dried and then applied with medicine.

⑤ Sick dogs with severe purulent infection should use systemic antibiotics.

Acute wet dermatitis

This is an exudative dermatitis associated with severe secondary infection. Clinically, it is characterized by acute onset, obvious pain, and rapid spread. Pathological changes such as large-area redness and swelling, inflammatory exudation, suppuration, hair loss and scab appeared within 24 hours. It often occurs in dogs with dense coats, such as German Shepherds, and is more common in warm, humid summers.

During treatment, the coat around the lesion should be cut off, antiseptic disinfectant should be used to gently wipe off inflammatory secretions and scabs, and the local area should be kept dry or apply gentian violet, antibiotics and other agents.If there is itching, corticosteroids should be used. Dogs with severe pain and nervousness should use sedative and analgesic drugs.
