Hot spots (acute moist dermatitis) are rapidly developing, intensely painful bacterial skin infections in dogs that can expand dramatically if untreated. Understanding their welfare implications helps owners respond appropriately.
Hot spots cause acute, intense suffering that is often visible to owners - dogs with active hot spots may cry, bite at themselves frantically, and be unable to sleep from the burning discomfort. The rapid expansion of hot spots (a small area can become palm-sized within 24 hours) means that delayed treatment leads to dramatically increased pain and tissue damage. The self-trauma of licking and scratching causes open wounds that are painful in their own right. Treatment requires clipping away fur from a raw, painful lesion - uncomfortable even with pain management. Despite their dramatic presentation, hot spots are generally responsive to treatment, making the welfare cost of delayed or untreated cases particularly avoidable.
