A dog’s hotspot, or acute moist dermatitis, can appear almost out of nowhere and spread within hours. It is a reddened, moist, and extremely painful area of skin that the dog has caused by breaking the skin’s surface through scratching, licking, or chewing. Quick and correct action is crucial to bring the inflammation under control before it requires heavy medication.
There is almost always some underlying factor that originally irritates the skin. It could be an insect bite, an allergy, a small wound, or even matted fur that traps moisture against the skin. When the dog tries to relieve the itching or pain by licking, it breaks the skin’s protective barrier. Moisture and heat create an ideal breeding ground for bacteria, usually staphylococci that live on the dog’s own skin, and the cycle of inflammation is set.
How to recognise a hotspot? Typical symptoms
A hotspot is easy to identify once you know what to look for. It is not a sneaky ailment; its symptoms are clear and pronounced.
Watch for these signs:
- Well-defined area of skin: The inflammation is usually round and clearly distinguishable from the surrounding skin.
- Severe redness and swelling: The skin is irritated and inflamed.
- Moisture and discharge: The inflamed area secretes yellowish, sticky tissue fluid that glues the fur to the skin. This is the most characteristic feature of the condition.
- Pain and itching: The area is extremely sensitive to touch. The dog constantly tries to lick, scratch, or bite it, which quickly exacerbates the situation.
- Foul odour: A bacterial infection often produces an unpleasant, sweet smell.
- Location: Hotspots typically appear in areas that the dog can easily reach to lick: under the jaw, on the neck, hips, thighs, and base of the tail.
Breeds with thick and dense undercoats, such as Golden Retrievers, Bernese Mountain Dogs, and German Shepherds, are particularly prone to hotspots. Their fur dries slowly and easily traps moisture against the skin, creating perfect conditions for inflammation.
Home treatment for hotspots: first aid in three steps
A small and early hotspot can often be treated at home, provided action is taken immediately when symptoms appear. The most important thing is to stop the cycle of inflammation and allow the skin to heal.
1. Shaving the fur
This is a very important and often critical step in treatment. The inflamed skin needs air to heal. Use clippers to shave the fur generously around the inflamed area, at least 2–3 centimetres from the healthy skin. This way, you can see the true extent of the inflammation and prevent it from spreading under the fur. Do not use scissors, as they can easily cut the sore and swollen skin.
2. Cleaning and disinfecting
Carefully clean the shaved area 2–3 times a day. Use a non-stinging disinfectant available from pharmacies, such as diluted chlorhexidine solution. Dab the area with a cotton pad or gauze soaked in the solution – do not rub, as this may further irritate the skin. Cleaning removes bacteria and dried discharge.
3. Preventing licking
The dog must absolutely wear an Elizabethan collar or another licking prevention device. Without it, the dog will lick the treated area back to a state of injury in no time, rendering all your efforts futile. The collar should be kept on continuously until the skin has clearly healed and is no longer red or discharging.
Avoid thick, greasy ointments, as they can trap moisture against the skin and worsen the inflammation. Allow the skin to breathe and dry.
When is it time to consult a veterinarian?
Home treatment is not always sufficient, and sometimes professional help is necessary. Do not hesitate to contact a veterinarian if:
- The hotspot is very large or appears deep.
- The dog is in so much pain that it will not allow you to shave the fur or clean the area safely.
- The inflammation does not begin to subside after 1–2 days of home treatment, but instead spreads or worsens.
- The dog appears generally unwell, feverish, or apathetic.
A veterinarian can clean and treat the area under sedation, prescribe more effective topical treatments (such as corticosteroid sprays for itching), and if necessary, a course of oral antibiotics and pain relief.
Prevention: Four keys to avoiding hotspots
The best treatment is prevention. By understanding the causes of hotspots, you can effectively prevent their recurrence.
-
Thorough grooming: Regular brushing keeps the coat airy, removes loose undercoat, and prevents matting. Grooming is especially important for fluffy and thick-coated breeds. Professional grooming helps maintain the coat and keep the skin healthy.
-
Careful drying: Always dry your dog thoroughly after swimming, bathing, or being out in the rain. Moist undercoat is a very common cause of summer hotspots.
-
Timely external parasite control: Flea and tick bites cause itching that triggers a scratching cycle. Keep your dog’s external parasite treatments up to date throughout the year.
-
Managing allergies: If your dog has recurring skin issues, there may be an underlying allergy. Discuss with your veterinarian whether it could be a food or environmental allergy. Addressing the root cause can also help prevent the development of hotspots.
