Abstract

SCHMIDT, Claudete et al. Central diabetes insipidus in a dog. Cienc. Rural [online]. 2009, vol.39, n.3, pp. 922-925. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782009000300046.

A case of central diabetes insipidus in a nine-year-old female dog is described. The dog presented intermitent polyuria and polydipsia in the past 18 months. In the clinical exam, complete blood count, alanine transaminase, alkaline phosphatase, BUN, creatinine, glucose and calcium dosages were normal. However, the specific urine gravity was low and presented the value 1002. The dog was unable to concentrate the urine during the seven hours of water deprivation test and presented 5% of dehydratation. The administration of desmopressin acetate elevated the specific urine gravity to 1028 five hours after the beginning of the treatment, confirming the diagnosis of diabetes insipidus of central origin.

Keywords : polyuria; polydipsia; desmopressin; diabetes insipidus; hypophysis.
