Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today.
Did the lumps just appear at the same time as her other signs?
Any ongoing issues/infections in her mouth?
Is she passing more urine then usual? Any diarrhea
Can she keep any water down?
Are her gums pink or pale/white? Moist or sticky?
If you press on her belly,does she have any discomfort, tenderness, or tensing?
Could she have eaten something she should not have (ie bones, toys, rocks, plants, chemicals, etc)?
Any other lumps that you can feel in her armpits, behind her knees, or in front of her fore legs?
