title: Primary anestrus due to dietary hyperthyroidism in a miniature pinscher bitch.
abstract: A 2-year-old intact miniature pinscher bitch that had been on a bones and raw foods diet since birth showed no signs of estrus despite a 40-day course of cabergoline. Elevated levels of thyroxine were detected in the serum (51 nmol/L) and in the juice of the meat (183 nmol/L) fed to the dog. Change in diet and treatment with oral cabergoline resulted in signs of proestrus in 13 d, pregnancy, and normal birth of 5 puppies.
