Q. Our 5yo lab mix recently started eating less...not greeting us at the door...just laying around...sad...her backbone is noticeable...now vomiting. ??
A. Schedule an exam with your vet. Weight loss, lethargy and vomiting can be serious symptoms. Blood work (CBC, chemistry panel, urinalysis) should be submitted to assess major organ function. Abdominal xrays or ultrasound can diagnose tumors or enlarged organs (organomegaly). Your vet can address the vomiting with supportive care and anti emetics if indicated.
