A hot spot, also known as acute moist dermatitis, is a skin irritation that develops rapidly and can be very uncomfortable for your dog. It is typically a circular or oval-shaped area of skin that is inflamed, red, and moist.

Hot spots can be caused by a variety of factors, such as allergies, insect bites, poor grooming habits, skin infections, and underlying medical conditions. Dogs that are prone to hot spots may also develop them due to stress or boredom. Some dogs will be more likely to develop hot spots.

You may notice your dog scratching or biting at a particular area of their skin, which can lead to hair loss, redness, and oozing. Hot spots are often accompanied by a foul odour and can be quite painful for your dog.

Treatment for hot spots typically involves cleaning the affected area and applying a topical spray, shampoo, conditioners, ointment or cream to help reduce inflammation and promote healing. In more severe cases, your veterinarian may also prescribe antibiotics or steroids to help manage the infection and reduce pain and itching.

To prevent hot spots in dogs, it is important to maintain good grooming habits, keep your dog's skin clean and dry, and address any underlying medical conditions or allergies that may contribute to the development of hot spots. Regular flea and tick treatment can also help reduce the risk of hot spots.

If your dog has a hot spot that is larger than a 10 cent coin (AUD) or is accompanied by fever, lethargy, or other signs of illness, it is important to seek veterinary care as soon as possible. Additionally, if your dog is prone to recurrent hot spots, your veterinarian may recommend a comprehensive evaluation to identify any underlying causes.
