She has and off and on appetite. Has not really been acting so much herself of late however.

I'm sorry to hear of this with your boxer. Bleeding and swelling as you've described arising so many years after spaying is worrisome for neoplasia (cancer) in an elderly Boxer. Her vet will want to scope your boxer's vagina looking for a mass lesion associated with the uterine stump, cervix, or vagina. If such a mass can't be visualized, an abdominal ultrasound would be the next diagnostic of choice in order to visualize what can't be seen by scoping. Please note that an otoscope (instrument used to scope ears) is not an appropriate type of scope to thoroughly examine the vaginal vault; hence, your boxer might need to be referred to a specialist internist (please see here: for scoping.

Please respond with further questions or concerns if you wish.
