Please hold off on the spay,at this point it’s elective and not at all a priority. I understand your angst about invasive diagnostics but IMO that is the ONLY way to proceed…you have to have a definitive diagnosis to be able to know what to do next…anything less is too much trial and error. I had my Boxer bitch scoped (endoscopy and colonoscopy) a little after 2 and she’ll be to this May (IBS/colitis). It has been helpful to know how and what to feed her. We’ve had other GI issues along the way (hemmoragic gastritis,bowel resections,polyps,pancreatitis flares with the IBS…) but overall she has fared well and you’d never know to look at her she copes with illness. I’ve had success with Hill’s Ultra Z/D,Honest Kitchen Zeal and Force and home cooking….turkey and oatmeal and veggies run through the food processor.
