Causes
Anything that triggers localised itching or pain: a bite, an allergy, an infected ear, a matted knot of hair, trapped moisture. Dense-coated breeds (Golden Retriever, Labrador, St Bernard) are more prone.
Diagnosis
Immediate visual diagnosis. The vet looks for the underlying cause that started the scratching.
Treatment
Clip the area, clean, dry and apply topical treatment. Sometimes an Elizabethan collar to stop the licking. Treat the underlying cause.
Prevention
Dry the coat well after baths or rain, brush regularly to prevent matting, control parasites, treat ear infections promptly.
