Perianal Adenoma is a low-severity cancer condition that can affect dogs of all ages and breeds. Perianal adenomas are benign tumours of the hepatoid glands surrounding the anus. They are testosterone-dependent and almost exclusively affect intact male dogs. They are cured by castration in the majority of cases. It is documented across 1 breed, though prevalence and severity can differ significantly between them. It typically becomes apparent at 7-10 years. Early signs to watch for include lumps around the anus, licking at perianal area, occasional bleeding or ulceration, and scooting. When treatment is required, costs are estimated at £300-£1,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.

Signs & Symptoms

The following symptoms are commonly associated with Perianal Adenoma in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.

• Lumps around the anus
• Licking at perianal area
• Occasional bleeding or ulceration
• Scooting

Treatment Overview

Castration causes regression of most adenomas within weeks. Any remaining or large tumours are surgically excised. Regular perianal monitoring in intact males.

Typical onset: 7-10 years

Prevention & Screening

While not all cases of Perianal Adenoma can be prevented, the following steps reduce risk or enable earlier intervention:

• Castration is preventive
• Regular examination of perianal region in intact males
