Causes of dog testicular epidermal ulceration:

1. For ulcers caused by fungal infection, we must first use antifungal drugs.

2. It may also be ulcers caused by autoimmune disorders, which are commonly known as allergies. In this case, we will choose to use hormones or cyclosporine for treatment.

3. Bacterial infection causes skin ulceration on the dog's testicles. At this time, we need to choose antibiotics for sterilization treatment. The type of antibiotics is best determined based on the results of the drug sensitivity test.

4. The dog accidentally caused trauma during activities, and did not deal with it in time or wear a collar, resulting in skin ulceration.

Treatment methods for canine testicular epidermal ulceration:

1. The owner needs to take the pet to the pet hospital immediately for disinfection and anti-inflammatory treatment. In severe cases, a doctor may be required to help with suturing.

2. If the situation is serious, it is recommended to wrap it with gauze and then tie it to the back to fix it.

3. Before the affected area is healed, wear an Elizabethan ring on the dog to prevent licking.
