Hot Spot in Dogs - What is it

Hot spots in dogs: What they are, how they develop, and what you can do about them

Have you ever heard of hot spots in dogs? These nasty, itchy, and oozing patches of skin can be quite tormenting for your pet. If you feel like your dog suddenly starts scratching or even licking a certain area like crazy until the skin becomes red and irritated, it could be a hot spot. Let's take a look at what hot spots are, why they occur, and what you can do about them.

What is a hot spot?

A hot spot is an inflamed, irritated area of ​​skin that often appears suddenly. These spots are usually red, oozing, and often accompanied by hair loss in the affected area due to the dog's constant licking or scratching. This skin irritation is also known as "acute moist dermatitis." What's particularly nasty is that hot spots can spread very quickly if not treated promptly. They usually start small, but within a few hours, the inflamed area can become significantly larger.

Causes of hot spots

There are many reasons why dogs develop hot spots. Here are some common causes:

1. Allergies : Many dogs suffer from allergies—whether to certain foods, pollen, or flea bites. These allergic reactions can lead to severe itching, causing your dog to scratch and lick themselves intensely.
2. Flea infestation : Fleas and other parasites are one of the most common causes of hot spots. Even a single flea bite can trigger an allergic reaction in sensitive dogs, triggering itching that leads to the development of a hot spot.
3. Humidity and warmth : Dogs who swim a lot or spend time outdoors in rainy weather are at increased risk for hot spots. Their skin often remains moist beneath their thick fur, and this combination of humidity and warmth creates a perfect environment for bacteria.
4. Skin injuries : Minor injuries, such as cuts or scratches, can also cause a hot spot. If the dog then continually licks or scratches the area, the skin can become inflamed and worsen the wound.
5. Stress and boredom : Yes, psychological factors can also play a role. Dogs who are stressed or bored tend to lick or bite themselves, which can ultimately lead to hot spots.

Symptoms of a hot spot

Hot spots are usually quite easy to identify.

• Reddish and inflamed : The skin looks red and irritated.
• Moist and weeping : The inflamed skin often has a moist sheen because your dog is constantly licking itself.
• Bald : Hair falls out or breaks off in the affected area.
• Itchy and painful : Your dog will scratch, bite, or lick the area vigorously. This will cause the wound to worsen and become even more infected.

Treating a hot spot

Once you discover a hot spot on your dog, it's important to act quickly and consult a veterinarian first. Here are some additional tips:

1. Trim the fur : Carefully trim the hair around the affected area to allow air to reach the wound and make it easier to clean.
2. Cleansing : Cleanse the inflamed area of ​​skin with a mild antiseptic solution, such as diluted iodine. This helps reduce bacteria on the skin and prevents the inflammation from spreading further.
3. Drying : An important step is to dry the area thoroughly, as moisture promotes the spread of bacteria.
4. Cool compresses : You can cool the affected area with a cold, damp cloth to relieve inflammation and itching.
5. Preventing scratching : To discourage your dog from constantly licking and scratching, you can use a dog collar (cone). This gives the wound a chance to heal.
6. Visit a vet : In severe cases, you should definitely see a vet, as antibiotics or special ointments may be necessary.

Prevention of hot spots

Of course, prevention is always better than cure! Here are some tips:

1. Regular grooming : Brush your dog's coat regularly, especially if he has long or thick fur. This will remove dead hair, dirt, and potential parasites.
2. Flea protection : Make sure your dog is treated for fleas regularly. Flea prevention is essential to avoid hot spots.
3. Dry thoroughly : If your dog gets wet – whether after a bath or a walk in the rain – dry him thoroughly, especially in the folds of his skin and under his thick coat.
4. Identifying and treating allergies : If you suspect your dog is suffering from allergies, talk to your veterinarian about possible treatments or food changes.
5. Stress reduction : Make sure your dog gets enough exercise and mental stimulation. This will prevent him from licking himself out of boredom or stress.
