How to treat a dog’s hot spot at home

Hot spots, also known as acute moist dermatitis, are common skin lesions that can appear suddenly on a dog’s body, usually as red, inflamed, and moist patches.

These lesions often develop as a result of constant licking, chewing, or scratching, which causes a break in the skin that then becomes infected by bacteria. While hot spots can be alarming due to their appearance and rapid development, many mild cases can be managed at home if addressed early and appropriately.

How to treat a dog’s hot spot at home

The first step in treating a dog’s hot spot at home is to gently trim or clip the hair around the affected area. This allows air to reach the skin and makes it easier to clean and treat. It's important to use blunt-tipped scissors or a pet grooming clipper and proceed carefully to avoid causing further irritation or injury. After exposing the hot spot, the area should be cleaned with a mild antiseptic solution, such as diluted chlorhexidine or povidone-iodine.

These solutions help disinfect the wound without causing too much discomfort to the dog.

Once the hot spot is clean and dry, applying a topical product designed for skin infections can help reduce inflammation and combat bacterial overgrowth.

There are various sprays, gels, or creams formulated for pets that contain ingredients like hydrocortisone (to reduce itching) and antibiotics (to fight infection). It’s crucial to prevent the dog from licking or chewing the treated area, which can be done by using an Elizabethan collar or a soft recovery cone.

Keeping the dog’s environment clean and minimizing stress are also important components of at-home care. Dogs often develop hot spots due to underlying causes such as allergies, flea infestations, poor grooming, or boredom.

Addressing the root cause — whether it’s improving flea control, changing the diet, or offering more mental stimulation—can prevent recurrence. If the lesion worsens, spreads, or doesn’t improve within a few days, it’s essential to consult a veterinarian, as prescription medications or further diagnostics may be needed.

Hot spots can be painful and irritating for dogs, but with prompt attention and proper care, most mild cases resolve quickly. By understanding how to treat them at home and when to seek veterinary help, pet owners can ensure their dogs recover comfortably and safely.
