Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
How long have you been giving her aspirin? Before or after this started?
Any black stool?
Any vomiting or retching?
Are her gums pink or white/pale?
If you press on her belly, does she have any tensing, soreness, discomfort, or tenderness?
Could she have eaten anything she should not have (ie toys, bones
, socks, rocks, plants, people medication, toxins, etc)?
