Technically, the condition is also known as circumanal or hepatoid adenomas.

Ultimately, a biopsy of any tumors can confirm the condition.

Generally, treatment for the condition for male dogs focusses on castration.

Additionally, any tumors can be removed by a process called cryotherapy. This freezes the tumors off.
