Hello, I'm a veterinary expert with a strong focus on animal dermatology. I'm here to provide you with an in-depth understanding of what causes hot spots in dogs. Hot spots, or acute moist dermatitis, are a common skin condition that can be quite distressing for our canine companions.

Hot spots, scientifically known as acute moist dermatitis (AMD), are areas of skin that become inflamed, moist, and often infected due to excessive licking, chewing, or scratching. They can develop rapidly, sometimes within just a few hours, and can be quite painful for the animal.

The primary cause of hot spots is trauma to the skin. This trauma can be caused by a variety of factors, including:


1. Allergic Reactions: Dogs can develop allergies to various substances, such as food, pollen, or chemicals in household products. These allergies can lead to skin irritation and itching, prompting the dog to lick or scratch the area.


2. Insect Bites: Bites from insects like fleas, mites, or mosquitoes can cause localized inflammation and itching, which can then lead to hot spots if the dog continues to lick or scratch the bite area.


3. Poor Grooming: Dogs with long hair that isn't regularly brushed can develop mats or tangles, which can trap moisture and irritate the skin. This can create an environment conducive to the development of hot spots.


4. Underlying Infections: If a dog has an underlying ear or skin infection, the itching and discomfort associated with the infection can lead to excessive licking or scratching, which can then result in hot spots.


5. Stress or Boredom: Dogs may also lick or chew on themselves out of stress or boredom. This repetitive behavior can cause enough trauma to the skin to initiate a hot spot.

It's important to note that hot spots can become infected very quickly due to the moist environment they create, which is conducive to bacterial growth. This is why it's crucial to address hot spots promptly to prevent further complications.

When treating hot spots, a veterinarian will typically:

- Clean the area to remove any debris and dead hair.
- Apply a topical antibiotic to help prevent or treat infection.
- In some cases, prescribe oral antibiotics or anti-inflammatory medications.
- Recommend伊丽莎白an (E-collar) to prevent the dog from continuing to lick or scratch the area.

Prevention of hot spots includes regular grooming to prevent matting, addressing any underlying allergies or infections, and providing mental stimulation and exercise to reduce stress and boredom.

Now, let's move on to the translation of the above information into Chinese.
