Managing interdigital furuncles and cysts in dogs — recurrent, painful conditions affecting paw welfare.
Interdigital furuncles cause significant localised pain and distress. The nodular lesions are exquisitely tender — affected dogs lick obsessively at their feet, show lameness, and resist having their paws handled. When lesions rupture, they discharge haemorrhagic or purulent material, providing temporary relief but risking secondary infection and worsening the cycle.
The chronic, recurrent nature of interdigital disease is frustrating for both dogs and owners. Multiple treatment courses — antibiotics, anti-inflammatory medications, surgical excision — may control individual episodes without addressing the underlying predisposing factors. Dogs with recurrent disease live with cycles of pain, treatment, apparent recovery, and relapse.
Addressing predisposing factors is essential for lasting welfare improvement. Obesity increases interdigital pressure and friction. Conformation in flat-footed breeds creates conditions favouring hair impaction. Demodicosis must be excluded as an underlying cause. Immunosuppressive conditions predispose to recurrent bacterial infection. CO2 laser treatment offers effective resolution of persistent lesions with reduced recurrence rates.
