When people typically think of a hotspot, they think of Wi-Fi hotspots. However, dogs and sometimes cats can get hotspots too. Hotspots can be found anywhere on a dog’s body, most notably on the head and neck region, axillary region, inguinal region, and paws. Hotspots are also known as acute moist dermatitis or pyotraumatic dermatitis. Hotspots usually involve red and inflamed skin lesions that can ooze clear to reddish discharge, or even pus, also known as purulent discharge, which is an indication of a bacterial infection. Hot spots are often the result of excessive scratching, licking, and chewing of the affected area. While insect bites typically remain localized, a hotspot can spread rapidly and become a painful, inflammatory lesion. If left untreated, a secondary bacterial infection can ensue.
Symptoms of hotspots typically involve constant licking, scratching, and sometimes a foul odor, which may indicate an active bacterial infection. The treatment for hotspots typically varies, depending on the severity of the skin infection. The first step to treating a hotspot is taking your pet to your trusted veterinarian. Your veterinarian will most likely clip the affected area and disinfect the hotspot prior to prescribing the appropriate treatment. Your pet may or may not require antibiotics or pain medications. Fortunately, most hotspots usually resolve in a few days if the directions of the veterinarian are followed.
The following are common causes of hotspots:
- Allergies
- Ear or skin infections
- Ectoparasites
- Flea allergy dermatitis
- Atopic dermatitis
- Contact dermatitis
- Matted or dirty coat
- Excessive licking
