Causes, symptoms and prevention measures of dog dermatitis

Causes of dog dermatitis:

The etiology of canine dermatitis is varied. It can be roughly divided into: mechanical, chemical, fungal, parasitic, allergic and other factors.

1. Mechanical: Traumatic dermatitis caused by abrasions, autogenous contusions, scratching, burns, frostbite, radiation damage, etc.

2. Chemical properties: long-term stimulation by chemical bath agents, rubbing irritating drugs, and purulent secretions.

3. Fungi: Microsporum, gypsum-like Microsporum, Trichophyton mentagrophytes.

4. Parasites: such as Demodex, scabies, cicadas, lice, fleas, schistosomes, hookworms, etc.

5. Food allergies and drug allergies can lead to dermatitis.

Dog Dermatitis Symptoms:

1. The dog's skin is red and swollen in flakes, strips or indeterminate shapes, covered with scabs. When the skin is damaged, erosions or ulcers may appear, and local pain and itching may occur.

2. When the skin is covered by a large amount of inflammatory exudate, it can be seen that the skin hair falls off, the skin thickens, and chapped.

3. When suffering from fungal dermatitis, the affected part will lose hair, and there will be white powdery scabs locally, and red protrusions under and around the scabs.

4. When suffering from parasitic dermatitis, red rash-like nodules can be seen on the head, back and abdomen, with yellow scabs on the surface, hair loss and severe itching.

Prevention and treatment of dog dermatitis:

1. Desensitization and antipruritic: Oral or intramuscular injection of corticosteroids, prednisone 1 mg/kg body weight, dexamethasone 0.15-0.25 mg/kg body weight.

2. Apply sulfonamide ointment locally.

3. Chronic dermatitis can be applied with triamcinolone acetate ointment or hydrogen acetate ointment.

4. For fungal dermatitis, clotrimazole ointment, tinea net ointment or dactomin ointment can be rubbed.

5. For dermatitis with bacterial infection, systemic application of antibiotic therapy, intramuscular injection of penicillin or gentamicin, 2 times/day.
