Case Report: Diabetes Mellitus in a Yorkshire terrier.

ABSTRACT

One week after the onset of polyuria, polydipsia, lethargy and weight loss and a one-day history of anorexia and vomiting, a 3.9kg, middle aged, spayed female Yorkshire terrier was presented to the Veterinary Teaching Hospital. Clinical examination was unremarkable except for cranial abdominal pain. Based on blood analyses, radiographic findings, and urinalysis, a diagnosis of diabetes mellitus was made. Insulin therapy was initiated at the hospital and adjusted appropriately based on monitoring clinical signs and serial blood glucose determinations. Despite acheiving adequate glycaemic control in the hospital environment, this dog developed cataracts after two months of therapy at home, but was otherwise clinically normal.
