I am sorry about your dog. Anal Sac Adenocarcinoma in dogs is uncommon cancerous tumor but is aggressive. It has tendency to metastasize to other parts of the body like lymph nodes, kidney and lungs. This cancer is diagnosed when lot of damage is already done. Initially tumors are small and are not diagnosed. Large size tumors (more than 10cm) are difficult to remove. After surgery recurrence is also common.
Surgery followed by chemotherapy and radiotherapy can improve quality of life to some extent but with poor prognosis.
