Hot Spots in Dogs: What Are They, and How Do You Treat Them?

Spotted some red, oozy and inflamed patches on your dog? They might have hot spots. These are one of the most common and frustrating skin conditions that pet owners encounter. These painful, inflamed areas of skin can appear suddenly and spread rapidly if left untreated. Understanding what causes hot spots and how to treat them effectively is crucial for maintaining your dog's health and comfort.

What Are Hot Spots in Dogs?

Hot spots, medically known as acute moist dermatitis or pyotraumatic dermatitis, are localised areas of skin inflammation and bacterial infection. These red, moist, and often oozing lesions develop when dogs repeatedly scratch, lick, or chew at their skin due to irritation or underlying conditions. The constant trauma to their skin’s protective barrier creates an ideal environment for bacterial growth, leading to the characteristic appearance of hot spots. Hot spots are typically found on the head, chest, hips, or limbs, but they can occur anywhere on your dog’s body.

Common Causes of Hot Spots

Understanding the root causes of hot spots is essential for effective treatment and prevention. Several factors can trigger these painful skin conditions:

Allergies

Environmental allergens, food sensitivities, and flea allergies are primary culprits. When dogs experience allergic reactions, they often scratch excessively, creating wounds that develop into hot spots.

Poor Grooming

Dogs with thick, dense coats or those that swim frequently may develop hot spots if their fur doesn't dry properly. Trapped moisture creates an ideal breeding ground for bacteria.

Insect Bites

Flea bites, mosquito bites, or other insect stings can cause intense itching, leading to excessive scratching and subsequent hot spot formation.

Stress and Boredom

Some dogs develop compulsive licking or scratching behaviours when stressed or bored, which can result in self-inflicted wounds that become infected.

Underlying Skin Conditions

Conditions like dermatitis, ear infections, or anal gland problems can cause discomfort that leads to excessive scratching or licking.

Identifying Hot Spots: Signs and Symptoms

Recognising a hot spot early can make treatment easier and prevent complications. Common symptoms include:

- Red, inflamed patches of skin that appear suddenly
- Moist, oozing lesions that may have a foul odour
- Hair loss in the affected area
- Intense scratching, licking, or chewing at specific spots
- Signs of pain when the area is touched
- Behavioural changes such as restlessness or decreased appetite

If left untreated, hot spots can spread quickly and lead to deeper skin infections requiring veterinary care.

Treating Hot Spots in Dogs

It’s best to bring your dog to the veterinarian, as they would be able to attend to the issue immediately, prescribe pet medication for dogs, and prevent further infection. 

However, if you are unable to get to a vet right away, here are some things you can do before your appointment to mitigate the issue: 

Step 1: Clip the Fur Around the Area

Trimming the hair allows airflow and prevents further matting around the infected skin. Use dog hair clippers to avoid accidentally cutting your pet’s skin. 

Step 2: Clean the Hot Spot

Use a gentle, antiseptic pet-safe solution to clean the wound. Avoid harsh human disinfectants like hydrogen peroxide or alcohol, which can delay healing.

Step 3: Apply a Hot Spot Spray for Dogs

One of the most effective first-line treatments is using a hot spot spray for dogs. These sprays are designed to:

- Reduce itching and irritation
- Provide antibacterial or antifungal protection
- Promote faster healing
- Prevent your dog from further chewing or licking

Look for a spray with soothing ingredients like aloe vera, tea tree oil (in safe, diluted amounts), or hydrocortisone to calm inflammation.

Step 4: Prevent Licking or Scratching

Use a cone to stop your dog from irritating the area further.

Continue monitoring the area to see if it heals or worsens, and reach out to your vet to address the underlying issue. Your vet may prescribe stronger topical ointments, oral antibiotics, or pet medication for dogs and cats if the infection is advanced. 

Final Thoughts

Hot spots are a painful and frustrating condition for dogs and their owners. The good news is that with prompt treatment and preventive care, they can be managed effectively. A hot spot spray for dogs is often the first line of defence, offering fast relief and preventing the condition from worsening.

If your dog struggles with frequent hot spots, consult your veterinarian to identify underlying causes and create a long-term management plan. With the right care, your dog can enjoy healthy, itch-free skin.
