Hot Spots on Dogs Overview:

Hot spots also known as acute moist dermatitis are localized areas of inflamed infected skin that appear suddenly and worsen quickly. These raw red patches are often painful itchy and can develop within hours due to licking chewing or scratching. They are one of the most common skin issues in dogs and can be triggered by underlying conditions like allergies flea bites or poor grooming.

Understanding the cause and managing hot spots promptly is key to preventing further skin damage and discomfort.

Hot spots are not a primary disease but rather a symptom of an underlying issue that causes dogs to irritate their own skin. Common causes include:

Flea bites or insect stings
Food or environmental allergies
Ear infections or anal gland issues
Excessive moisture from swimming or rain
Poor grooming or matted fur
Skin wounds or irritations
Stress anxiety or boredom leading to overgrooming

Certain breeds with thick coats such as Golden Retrievers Labradors and German Shepherds are more prone to developing hot spots.

Hot spots can appear anywhere on a dog’s body but are most common on the head neck hips and limbs. Signs to watch for include:

Red inflamed or swollen skin
Moist oozing or crusty lesions
Hair loss around the affected area
Constant licking chewing or scratching
Pain when touched or signs of irritation
Foul odor from the skin

These lesions can spread quickly if not treated and may lead to secondary bacterial infections.

Diagnosis is typically made through a physical examination but additional steps may include:

Skin scraping or cytology to rule out parasites and infection
Flea combing or checking for flea dirt
Allergy testing if symptoms are recurrent
Assessing grooming and hygiene habits
Reviewing diet environment and behavior

The goal is to identify the root cause to prevent recurrence.
