Dog Immune-Mediated Skin Disease Management

Immune-mediated skin diseases including pemphigus foliaceus and lupus erythematosus cause significant welfare problems requiring specialist diagnosis and long-term immunosuppression.

Key Facts

Pemphigus foliaceus is the most common autoimmune skin disease in dogs causing pustules and crusting
Discoid lupus erythematosus causes depigmentation and erosion of the nose and face
Diagnosis requires skin biopsy with immunofluorescence or immunohistochemistry
Prednisolone and additional immunosuppressants including azathioprine or mycophenolate are used
Remission is achievable in many cases but lifelong monitoring may be required

Welfare Considerations

Immune-mediated skin diseases cause chronic discomfort from painful skin lesions, pruritus, and secondary infections. The face and nose are commonly affected, impacting social communication and daily comfort. High-dose immunosuppression causes significant side effects including polyuria, polydipsia, and increased infection susceptibility. Finding the minimum effective dose that maintains remission while minimising side effects is a central welfare management goal. Specialist dermatological input improves outcomes.

What You Can Do

Seek specialist veterinary dermatology assessment for suspected immune-mediated skin disease
Request skin biopsy for definitive diagnosis before committing to long-term immunosuppression
Follow dose tapering protocols carefully to find the minimum effective maintenance dose
Monitor regularly for side effects and secondary infections during treatment
Protect affected skin from sunlight as UV exposure can worsen lesions
