Thank you for submitting your question regarding Siri. I would recommend stopping her NSAID medication and having her evaluated by her veterinarian . A side effect of this medication, is gastrointestinal tract ulcers. This can be seen as black tarry stool in a dog or vomiting blood. I hope this information helps.
