Acute moist dermatitis, commonly known as hot spots, is a frequent and uncomfortable skin issue in dogs. These irritating, inflamed sores can erupt quickly on any part of the body but are often seen around the ears and neck. The affected skin often appears red, moist, and may ooze yellowish fluid accompanied by a strong, unpleasant smell.
If your dog has been diagnosed with acute moist dermatitis or you suspect your pet may be showing symptoms, this detailed guide covers the typical causes, methods for diagnosis, treatment options, and preventive steps to help you manage this condition with confidence and care.
Dogs with thick, dense, or long hair are particularly susceptible, as their coats can trap moisture against the skin, fostering an environment where bacteria thrive and irritation develops. Poor grooming that results in matted fur or trapped dirt increases the risk significantly.
Usual causes include:
Hot spots are most common during the warm, humid months in many parts of the U.S., as heat plus moisture accelerate the growth of harmful bacteria and exacerbate skin inflammation.
If you observe any suspicious inflamed spots on your pet, scheduling a visit with a veterinarian is crucial. The vet will conduct a thorough exam and might perform a skin scraping to eliminate other issues like yeast or fungal infections that can mimic hot spots.
Treatment typically involves:
Seeking prompt veterinary assistance ensures a faster recovery and helps stop the condition from worsening or spreading.
While it’s not always possible to completely prevent hot spots, implementing these measures can go a long way in reducing your dog's chances of developing them and in catching flare-ups early:
Should you notice new or ongoing hotspots, contact your veterinarian to confirm the cause and get appropriate treatment. Managing underlying issues such as flea infestations or allergies is key to preventing recurrent outbreaks.
Treating the physical symptoms of hot spots is important, but uncovering and addressing what caused them is just as vital. Allergies, flea problems, ear infections, or musculoskeletal discomfort can drive your dog to itch or lick excessively, worsening skin damage and promoting acute moist dermatitis.
Responsible pet ownership involves keeping up with regular parasite prevention, consistent grooming routines, and scheduled veterinarian visits to ensure your dog’s skin and overall health stay in good shape year-round.
For example, breeds like the Golden Retriever and Labrador Retriever are prone to hot spots due to their thick double coats, especially in humid states like Florida or Louisiana.
