What Is a Hot Spot on a Dog?
Hot spots, also known as acute moist dermatitis, are painful red areas of skin that appear to be irritated and are sometimes raised.
Hot spots on dogs can occur anywhere on the body, but they are commonly found on the face, neck, limbs, or hips. The size and appearance of the lesions can vary slightly in each location, but most will look similar regardless of where they are.
These dog hot spots can appear quickly, usually with some degree of hair loss, and become much larger in a matter of hours.
Hot spots on dogs can be relatively minor and heal quickly. But they do have the potential to cause more serious issues, such as deeper skin ulcerations.
What Causes Hot Spots on Dogs?
Certain breeds are predisposed to skin conditions, including hot spots. Commonly affected breeds include Labrador Retrievers, Golden Retrievers, English Bulldogs, and German Shepherds.
Most hot spots on dogs are caused by an underlying condition that either causes itchiness, excessive licking, or excessive moisture. The most common issues include:
• Allergies (flea allergy, food allergy, or seasonal allergies)
• Ear infections
• Excessive moisture from swimming
• Excessive licking
• Poor grooming

Hot Spot Treatment for Dogs:
While some dog hot spot treatments can be done at home, the underlying cause should always be identified by a veterinarian, if possible, to prevent more hot spots from occurring.
To determine the underlying cause of your dog’s hot spot (especially for large or overly infected hot spots on dogs), a veterinary exam is necessary. It’s even more urgent if the affected area is:
• Increasing in size
• Consistently bleeding
• Displaying colored discharge
• Has any discharge, moisture, odor, or pain
You should also seek veterinary attention sooner if you cannot keep your pet from licking or scratching at the hot spot.
