Seasonal Hot Spots: Why Summer Might Be Worse for Your Dog

Summer can be a season of fun and outdoor activities for both humans and their canine companions. However, it also brings unique challenges for dogs, especially when it comes to their skin health. One common but often overlooked issue is the prevalence of hot spots, also known as acute moist dermatitis. These painful, inflamed skin lesions can develop rapidly, causing significant discomfort for dogs. While hot spots can occur at any time of the year, the warm, humid conditions of summer make this season particularly problematic. Understanding why summer exacerbates hot spots and how to prevent them is crucial for keeping your dog comfortable and healthy throughout the hotter months.

What Are Hot Spots?

Hot spots, also known as acute moist dermatitis, are localized areas of skin inflammation and infection that can develop rapidly in dogs. They usually present as red, moist, and often oozing patches of skin that are painful and warm to the touch. The appearance of hot spots can vary, ranging from small, irritated patches to large, ulcerated lesions that can cover significant portions of the dog's body. These sores can be intensely itchy and uncomfortable, leading dogs to lick, scratch, or chew at the affected area, which can exacerbate the problem and cause the hot spot to spread quickly.

Hot spots are triggered by anything that causes skin irritation or leads a dog to scratch or lick excessively. Common causes include:

• Allergies: Environmental allergens such as pollen, mold, and dust mites, as well as food allergies, can cause intense itching, leading to scratching and the development of hot spots.
• Insect Bites: Fleas, ticks, and other insect bites can irritate the skin and prompt excessive scratching or licking, creating the perfect environment for hot spots to form.
• Poor Grooming: Dogs with matted fur or dirty coats are at a higher risk for hot spots, as trapped moisture and debris can irritate the skin and foster bacterial growth.
• Skin Infections: Bacterial and fungal infections can break down the skin barrier, leading to inflammation and the development of hot spots.
• Underlying Medical Conditions: Conditions like hypothyroidism or Cushing's disease, which affect skin health and immune function, can increase the likelihood of hot spots.

Certain breeds are more prone to developing hot spots due to their physical characteristics. Dogs with thick fur, dense undercoats, or skin folds, such as Golden Retrievers, Labradors, German Shepherds, and Bulldogs, are particularly susceptible. The dense fur can trap moisture and heat close to the skin, creating an ideal breeding ground for bacteria and exacerbating the problem.

Why Summer Makes Hot Spots Worse

Summer brings a range of conditions that can significantly increase the likelihood of hot spots in dogs, making it a particularly challenging season for those prone to this skin issue. The combination of heat, humidity, increased outdoor activities, and a surge in allergens creates a perfect storm that can lead to the rapid development and worsening of hot spots.

Heat and Humidity: The warm, humid climate of summer is an ideal environment for bacteria to flourish. When a dog’s skin becomes damp due to sweating (yes, dogs sweat through their paws) or moisture trapped under fur, the elevated temperature and humidity can cause bacteria to multiply rapidly. This bacterial overgrowth can break down the skin's natural barriers, leading to inflammation and infection, which are the hallmarks of hot spots. In such conditions, even a minor itch or scratch can quickly evolve into a painful, infected hot spot.

Increased Moisture:Summer activities often mean more exposure to water—whether from swimming in pools, lakes, or oceans, playing in sprinklers, or simply getting caught in summer showers. While many dogs enjoy these activities, the moisture left on their fur can be problematic if not properly managed. Moisture trapped under a dog’s coat, especially in breeds with thick or long fur, can create a breeding ground for bacteria and fungus, leading to skin irritation and the development of hot spots. Dogs that aren’t thoroughly dried after getting wet are particularly susceptible, as the persistent dampness irritates the skin and encourages bacterial growth.

Allergies: Summer is peak season for environmental allergens like pollen, grass, mold, and insect bites, all of which can trigger allergic reactions in dogs. These allergens cause itching and skin irritation, prompting dogs to scratch, lick, or bite at themselves excessively. This self-trauma damages the skin’s surface, making it more vulnerable to infection and hot spots. Additionally, the increase in insect activity, including fleas and ticks, can lead to bites that irritate the skin and contribute to the cycle of itching and inflammation.

These summer-specific factors can quickly turn a minor skin irritation into a significant health concern. This means it’s crucial for dog owners to be extra vigilant during the warmer months, taking steps to keep their pets cool, dry, and protected from allergens.

Identifying Hot Spots in Your Dog

Early recognition of hot spots is essential to prevent them from spreading and becoming more severe. Hot spots can develop quickly, so being vigilant about changes in your dog's behavior and appearance is key to managing this condition effectively. Here are the common signs to look for:

• Excessive Licking, Chewing, or Scratching: One of the earliest and most noticeable signs of a hot spot is your dog repeatedly licking, chewing, or scratching at a particular area. This behavior indicates irritation or discomfort, which often triggers the formation of a hot spot.
• Red, Inflamed Patches of Skin: Hot spots typically present as red, inflamed areas on the skin. These patches are usually warm to the touch and may appear swollen or raised due to the underlying inflammation and infection.
• Hair Loss Around the Affected Area: As hot spots develop, you might notice hair loss around the irritated skin. This occurs because of the persistent licking and scratching, which can pull out fur and exacerbate the condition.
• Moist, Oozing Sores: Hot spots often progress to moist, oozing sores that may have a foul odor due to the bacterial infection. The affected skin can appear raw and may bleed slightly, especially if your dog continues to scratch or bite at the area.

If you observe any of these symptoms, it's important to address the hot spot promptly to prevent it from worsening. Left untreated, hot spots can expand rapidly, causing significant pain and discomfort for your dog. Immediate steps should include cleaning the area, preventing further irritation by using an Elizabethan collar or similar device, and consulting with your veterinarian for appropriate treatments.Over-the-counter products likeZarasyl Companion Barrier cream can help protect the site, and aid in the healing process.

Preventing Hot Spots During Summer

Preventing hot spots in dogs during the summer requires a proactive approach that combines good grooming habits, managing allergies, and keeping your dog’s skin dry and healthy. By taking these preventive measures, you can reduce the risk of hot spots and keep your dog comfortable throughout the season.

Regular Grooming: Maintaining a regular grooming routine is crucial, especially for breeds with thick, long, or dense coats. Regular brushing helps remove loose fur, dirt, and debris that can irritate the skin and cause matting. Mats can trap moisture and create a warm environment that fosters bacterial growth, increasing the likelihood of hot spots. Keep your dog’s coat well-trimmed, particularly in areas prone to matting, such as around the ears, neck, and hindquarters. For breeds that are especially prone to hot spots, consider professional grooming to ensure their coat remains manageable and healthy.

Keeping Skin Dry:Moisture is a major contributor to the development of hot spots, so keeping your dog’s skin dry is essential, especially after activities that involve water. After your dog swims, gets a bath, or is caught in the rain, dry them thoroughly with a towel, and use a blow dryer on a cool setting if necessary. Pay particular attention to areas where moisture can easily get trapped, such as under the collar, in skin folds, between the toes, and under the tail. Ensuring these areas are dry can significantly reduce the risk of hot spots by preventing the conditions that allow bacteria to thrive.

Managing Allergies: Summer is peak season for environmental allergens like pollen, grass, and insect bites, all of which can trigger itching and irritation in dogs. To manage these allergies, consider bathing your dog with a hypoallergenic shampoo to remove allergens from their coat. You can also use dog-friendly wipes after outdoor activities to clean their paws and fur, reducing the allergens they bring into your home. If your dog has severe allergies, consult your veterinarian about appropriate allergy medications or supplements that can help control itching and minimize the risk of hot spots.

Consistent care and attention to your dog’s grooming, moisture levels, and exposure to allergens are key to preventing the discomfort and pain associated with hot spots, allowing your dog to enjoy a happier, healthier summer.

Summer-Specific Care Tips

During the summer, taking a few extra precautions can significantly help in keeping your dog’s skin healthy and free of hot spots.

Avoiding Peak Heat: High temperatures can contribute to heat stress and moisture buildup on your dog’s skin, both of which can lead to hot spots. To minimize these risks, limit your dog’s outdoor activities during the hottest parts of the day, typically between 10 a.m. and 4 p.m. Instead, schedule walks, playtime, and exercise during the cooler morning or evening hours when the temperatures are lower and the risk of overheating is reduced. Keeping your dog in shaded areas or indoors with access to fans or air conditioning can also help keep them cool and prevent excessive sweating or moisture accumulation that might irritate the skin.

Monitoring Hydration and Diet: Proper hydration and a balanced diet are crucial for maintaining overall skin and coat health. Make sure your dog has constant access to fresh, clean water, especially in the heat, as dehydration can affect their skin's elasticity and barrier function, making them more susceptible to irritations. Consider adding omega-3 fatty acids to your dog’s diet, either through supplements or foods like fish oil, as these nutrients support healthy skin and can help reduce inflammation. A diet rich in high-quality proteins, vitamins, and minerals will also contribute to your dog's overall well-being, including their skin health.

Using Protective Gear: Dogs with sensitive skin, light-colored fur, or those prone to sunburn can benefit from additional protection against the sun’s harmful rays. Dog-friendly sunscreens are available and can be applied to vulnerable areas such as the nose, ears, and belly. Additionally, lightweight protective clothing like UV-blocking shirts can provide an extra layer of defense against sun exposure and help reduce the risk of skin irritation. These protective measures are particularly important for dogs that spend a lot of time outdoors or are exposed to direct sunlight for extended periods.

Paying close attention to your dog’s hydration, diet, sun exposure, and activity levels will go a long way in keeping their skin healthy and their summer enjoyable.

Conclusion

Hot spots can quickly turn from a minor irritation into a severe health issue for dogs, especially during the summer when heat, humidity, and allergens are at their peak. By recognizing the signs early and taking proactive steps such as regular grooming, keeping your dog dry, managing allergies, and avoiding peak heat, you can significantly reduce the risk of hot spots. Summer-specific care, including proper hydration, diet management, and protective gear, can further safeguard your dog’s skin health.
