Causes of a dog’s nose being rotten:

1. It may be caused by the dog hitting some sharp objects or scratching the cage.

2. It may be that the dog’s nose comes into contact with some corrosive chemicals, causing skin erosion.

3. It may be a fungal infection that causes the dog’s nose to scab and then ulcerate.

How to deal with a dog’s rotten nose:

1. The owner can dip a cotton swab in a little saline and apply it to the dog’s nose to clean it.

2. Use the ointment prescribed by the doctor and apply it as widely as possible on the dog’s nose.

3. After applying the ointment, the dog will feel uncomfortable. At this time, you need to wear an Elizabethan ring on the dog and try not to let it scratch its nose with its paws.

4. The owner should insist on applying medicine to the dog, and apply it two or three times a day.

5. The owner remembers to deworm the dog’s entire body.
