Dog in heat: Why is she sick, lethargic, and throwing up yellow bile?

My dog is in heat and has been for around 3-4 weeks. She was sick yesterday yellow bile twice and has been lethargic and tired since. Her tail is down when she walks and doesn't want to play. Any advice?

Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). I cannot rule out urinary tract/genital tract (uterine) inflammations infections from what you are describing. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
