I have a female guinea pig. She has swollen nipples (no discharge). We took her to the emergency vet because we noticed a bit of blood in her vaginal area. The x-ray showed that everything looked normal internally. She was placed on Enrofloxacin Suspension 10.2 mg/mL. I should note that the bleeding was very minimal and had completely stopped by the time we arrived at the clinic. She hasn't had any bleeding since, and she seems perfectly normal. Has anyone ever experienced this before?
