Calcinosis Cutis in Dogs: Skin Welfare and Management

Calcinosis cutis causes calcium deposits in the skin of dogs, often from steroid excess. This guide covers welfare impacts and management.

Key Facts

Calcinosis cutis involves pathological calcium deposition in the skin
Most commonly caused by hyperadrenocorticism (Cushing's) or prolonged steroid therapy
Lesions appear as firm, pale, gritty plaques on the neck, back, and groin
Secondary bacterial infection is very common, causing pain and welfare compromise
Treating the underlying cause leads to slow resolution over months
Topical dimethyl sulfoxide (DMSO) may accelerate calcium resorption

Welfare Considerations and Management

Welfare-centred management of calcinosis cutis requires treating the underlying cause (Cushing's disease or reducing steroid doses) while managing secondary infections. Antibiotics address bacterial complications. Regular bathing with mild antiseptic shampoos reduces bacterial load. Topical DMSO may speed calcium resorption in some cases. The condition causes significant discomfort — pain assessment and appropriate analgesia improve welfare during the resolution period, which can take 6-12+ months.

What You Can Do

Treat underlying Cushing's disease or reduce steroid doses to address the cause
Manage secondary bacterial infections with appropriate antibiotics
Provide gentle bathing and topical antiseptic care to affected skin areas
Assess and manage pain during the prolonged resolution period
