Decreases in urine specific gravity and urinary creatinine in dogs with different diseases but with normal renal function.
The subject of this study was to determine urine specific gravity (USg) and urinary creatinine (UCrn) in dogs with different diseases but with normal renal function. Sick dogs with different diseases were divided into nine groups. Dogs suffering from polyuria/polydipsia, vomits, diarrhoea and females in oestrus or pregnant were excluded from the studies. The healthy dogs served as a control group. Over a three-year period, a total of 267 dogs were examined clinically as well as using imaging and laboratory diagnostics methods. In sick dogs, USg and UCrn were found to be essentially decreased (except animals with neurological and uterine diseases, and neurological diseases, respectively), as compared with normal dogs. In clinically healthy animals of the control group, UCrn and USg did not significantly differ between the females and males. As for the control group, no correlation between UCrn/USg and the body weight/age was found, either.
