Dog Skin Diseases: Causes, Symptoms, and Treatments
Skin diseases in dogs are one of the main reasons for veterinary consultations. The skin is the body's largest organ and acts as a protective barrier against external agents. Any alteration can cause discomfort, pain, and impact the animal’s quality of life.
Importance of Early Diagnosis
Early diagnosis is essential to prevent serious complications. Many skin conditions can progress quickly, leading to infections and discomfort. Identifying symptoms early allows for proper treatment and improves your dog's health.
Common Symptoms of Canine Skin Diseases
- Intense itching and constant scratching.
- Localized or widespread hair loss.
- Inflammation, redness, and scaling.
- Ulcers, scabs, and open wounds.
- Pustules, lumps, or thickened skin.
- Unusual odor or abnormal secretions.
Most Common Skin Diseases in Dogs
- Flea Allergy Dermatitis (FAD): Allergic reaction to flea saliva. Treated with antiparasitics and environmental control.
- Atopic Dermatitis: Allergy to dust, mites, or pollen. Requires antihistamines, immunotherapy, and environmental management.
- Ringworm (Dermatophytosis): Highly contagious fungal infection. Treated with antifungal medications and hygiene measures.
- Malassezia Dermatitis: Yeast overgrowth on the skin. Managed with antifungals and medicated shampoos.
- Mange: Can be sarcoptic (highly contagious) or demodectic (related to immunosuppression).
- Seborrhea: Excessive sebum production, causing dry or greasy skin. Treated with specialized shampoos.
- Pyoderma: Bacterial infection with pustules and hair loss. Requires antibiotics and topical disinfectants.
- Folliculitis: Inflammation of hair follicles due to infections or immune problems.
- Hot Spots (Acute Moist Dermatitis): Painful, purulent inflammations triggered by allergies or wounds.
- Skin Lesions: From superficial wounds to pressure ulcers in large dogs.
- Hormonal Issues: Disorders like hypothyroidism or Cushing’s disease affect the skin.
- Behavioral Problems: Stress and anxiety can cause excessive licking and skin damage.
Diagnosis and Treatment
Veterinarians use Wood’s lamps, skin scrapings, cultures, allergy tests, and biopsies to identify the cause.
Treatment options include:
- Parasiticides for fleas and mites.
- Antibiotics and antifungals for infections.
- Corticosteroids and immunosuppressants for allergic or autoimmune cases.
- Medicated shampoos and topical treatments.
- Hypoallergenic diets for food allergies.
- Hormonal therapies for endocrine disorders.
