My 14 yr old Yorkie has large purplish discoloration all around the rectum. Could this be cancer? She won't let me near it, tries to bite me! This isn't like her at all. Not as playful but no other symptoms and stools look the same.

Unfortunately, a malignant tumor is always a possibly in a senior dog like Molly, but she could have injured herself or has infected anal sacs. It certainly sounds like it's painful to her if she won't let you near it and tries to bite you when you try to examine it. The only way to know for sure is to have her seen by a vet, and I would recommend taking her into one today or tomorrow. The vet can diagnose what is causing this discoloration and can discuss treatment options with you.
