The term `hot spot' refers to self-trauma to the skin, due to an underlying itchy or painful process such as allergies (bacteria, food allergy), parasites (fleas, mange mites), ear problems, environmental causes, musculoskeletal disorders, anal sack disorders.

They usually present as single, circumscribed sores which are often covered up by matted, wet fur following the dog licking, chewing or scratching the area. This occurs within hours. Once the fur is removed a thin yellow film is seen. The sore is usually painful.

When such a sore is detected by the owner the affected area must be exposed with scissors or clippers to allow the air to get to it. Following this the sore should be cleaned gently with either Chlorhexidine wash (Hibiscrub) or salty water. The key is to stop the dog from licking, chewing or scratching which might require a plastic collar or socks to avoid further trauma. You should then consult your vet as in almost all cases further treatment is required (e.g. antibiotic cream and/or tablets, anti-inflammatory drugs).

Your vet will then also be able to identify the underlying cause of the irritation and can treat it accordingly.
