If your pet is experiencing an anal sac adenocarcinoma, also known as a malignant tumor in his anal sac, perianal region, or rectal region, you may notice increased drinking and urination, as well as a loss of appetite. You may also notice excessive licking or "scooting," when your pet drags his bottom along the ground. If your pet is diagnosed with an anal sac adenocarcinoma, surgery can help.
