Have you ever noticed your dog constantly licking or scratching the same spot on its body during hot and humid days? Don’t be quick to assume it’s just a mosquito bite — it could be a skin infection. When humidity rises, dogs are highly prone to skin problems, and if not properly treated in time, the condition can become much worse. Here, Furry® shares 5 essential facts every dog owner should know about skin infections in dogs and how to handle them.
1. Skin Infections Are More Than Just Itchy Patches
Skin infections, also known as hot spots or moist dermatitis, are areas of inflamed, infected skin that cause intense discomfort for dogs. These areas are typically:
Red, moist, and warm to the touch
Matted with fur or oozing discharge
Painful and extremely itchy
If not treated promptly, skin infections can spread and lead to serious pain or deeper infections.
2. Humidity Is a Major Trigger for Skin Problems
One of the primary causes of skin infections is moisture buildup on the dog’s skin. In humid weather conditions:
Sweat and damp fur create a warm, moist environment ideal for bacteria
Fungi and bacteria thrive more easily
Dogs may lick or scratch more due to allergies or insect bites, further damaging the skin
If you live in a tropical or rainy climate, be extra cautious during the wet season!
3. Some Breeds Are More Prone Than Others
Dog breeds with thick or long coats are more susceptible to skin infections. These include:
Golden Retrievers
Labrador Retrievers
German Shepherds
Saint Bernards
Huskies
Why? Dense fur traps moisture and limits air circulation, creating the perfect breeding ground for bacteria. Daily brushing is a simple yet powerful way to prevent this.
4. Prevention Starts With Clean, Dry Grooming Habits
To prevent skin infections, focus on proper coat and skin care:
Brush your dog daily to remove dead hair and promote airflow
Thoroughly dry your dog after baths or walks in the rain — don’t leave the fur damp
Use antibacterial or anti-itch sprays if your dog has sensitive or allergic skin
Keep bedding and sleeping areas clean and dry at all times
A clean and dry dog is a healthy dog — especially in humid weather!
5. Visit the Vet If Symptoms Worsen
Not all skin infections can be treated at home. Watch for signs such as:
Inflamed skin that spreads or emits a bad odor
Your dog showing signs of pain, refusing to eat, acting tired, or obsessively licking one spot
No improvement after a few days of home care
In these cases, do not hesitate — take your dog to the vet immediately. Your vet may prescribe antibiotics, anti-inflammatory medication, or more intensive treatment to avoid complications.
Conclusion
Skin infections are among the most common — and potentially serious — skin issues dogs face during humid weather. Proactively preventing them by keeping your dog’s coat clean and dry and detecting early warning signs will help keep your furry friend healthy and comfortable.
