A 19-year-old 250-kg Quarter Horse mare was examined\udin the fall for evaluation of weight loss of 4 years’\udduration. The mare had been purchased 6 years before examination and was reported to be normal in appearance,\udweight, and demeanor. She had been used for trail riding.\udThe owner initially noticed weight loss following transient\udpostpartum diarrhea 4 years before presentation. The weight loss was mild and slowly progressed with intermittent\udperiods of soft feces. Referral for evaluation was prompted by marked weight loss over the preceding 6 months. The mare had a ravenous appetite and polydipsia. In addition, the mare did not completely shed her hair coat during summer and was heat intolerant in ambient temperatures that exceeded 32.2 1C (901F). This was manifested as lethargy, sweating, and increased respiratory rate
