primary polydipsia

excessive water drinking in hyperactive, stressed dogs. See also psychogenic diabetes insipidus.

psychogenic polydipsia

horses confined in a stall and having little or no exercise may drink excessively from boredom, up to three times normal amounts. It may also occur in dogs, apparently from psychological causes, with large amounts of water a day being consumed and a corresponding polyuria with a large volume of dilute urine produced. Yet, when water intake is restricted normal tubular function with concentration of urine is possible. See also psychogenic diabetes insipidus.
