E-mail: email@example.com The aim of the present study was to evaluate the effects of different fluid infusion rates on hematologic and urinary parameters in dogs. A total of 30 mixed-breed, male dogs were distributed into three groups. Fluid (0.9% NaCl) was administered during a one-hour period at rates: G5 (5 mL/ kg); G10 (10 mL/ kg); G50 (50 mL/kg). Blood samples for erythrogram, and urine to perform urine specific gravity were taken over the following time points studied. Urinary volume produced was also evaluated during the same time points. Erythrogram values were statistically lower between T10 and T240 in G10 and G50, compared to T0, and the lowest values were found in G50. Urine specific gravity decreased statistically between all time points only in G50. Statistical differences were found in urinary output between groups, with higher volumes in G50 in most of the time points studied, it can be concluded that fluid therapy changes hematologic indices in rates of 10 and 50 mL/ kg for one hour. At least a four hour period must be respected after the end of infusion to collect blood for erythrogram samples. Fluid therapy affects the urine specific gravity only at high infusion rates (50 mL/kg for 1 hour), and in this case urine samples should be collected after more than 4 hours after the end of infusion, although lower rates (5 and 10 mL / kg for 1 hour) do not interfere with urine specific gravity.
