Dog Hot Spots and Skin Welfare: Prevention and Care

Acute moist dermatitis (hot spots) are intensely painful, rapidly expanding skin infections that cause significant distress to affected dogs. Understanding triggers enables prevention and prompt treatment.

Key Facts

Hot spots (acute moist dermatitis) typically develop within hours when a dog licks, bites, or scratches at a localised area
Underlying triggers include flea allergy, food allergy, ear infection, anal gland impaction, and boredom-related overgrooming
Golden retrievers, German shepherds, and Labrador retrievers are predisposed due to coat type and anatomical factors
The lesion produces a moist, matted, painful area of skin that can expand from a centimetre to a dinner plate within 24 hours
Treatment requires clipping the hair, cleaning the lesion, topical antibiotic and steroid treatment, and often systemic antibiotics
An Elizabethan collar is essential to prevent self-trauma during treatment; without it, dogs persistently worsen the lesion

Welfare Considerations

Hot spots cause acute pain and intense pruritus that dogs cannot resist scratching and licking despite the pain this causes. The self-traumatic nature of the condition creates a pain-itch cycle: trauma worsens the lesion, which intensifies the itch, which drives more trauma. Without intervention, hot spots can expand extremely rapidly and become deeply infected. The welfare significance is highest in the early phase before treatment: untreated hot spots cause hours to days of intense distress. Prompt owner recognition and veterinary assessment are the key welfare interventions. Prevention requires addressing underlying triggers: dogs with hot spots associated with flea allergy require year-round flea prevention; those with food allergy need dietary management; those with boredom-related overgrooming need enrichment and behaviour support. The Elizabethan collar, while frustrating for dogs, is essential to allow healing.

What You Can Do

Learn to recognise early hot spots before they expand significantly
Seek veterinary assessment promptly when you notice your dog repeatedly licking or biting an area
Keep your dog on year-round flea prevention to remove the most common hot spot trigger
Use an Elizabethan collar or alternative protective garment during hot spot treatment
Investigate and address the underlying trigger to prevent recurrence
Keep the contact number of an out-of-hours veterinary practice for hot spots that develop overnight
