What should be checked to assess hydration status in canines?

Assessing hydration status in canines requires an understanding of physiological indicators. Capillary refill time is a valuable measure because it reflects peripheral perfusion and overall blood volume, which are directly influenced by hydration. By evaluating how quickly the gums return to their normal color after pressure is applied, one can gauge whether the animal is adequately hydrated; a prolonged capillary refill time may suggest dehydration.

Other indicators like urine color can provide insights into hydration status as well, indicating concentration levels, but they may be influenced by dietary factors or other health conditions. Heart rate can indicate stress or dehydration but is not a specific measure of hydration. Lastly, body temperature is important in assessing overall health but does not directly correlate with hydration status. Therefore, capillary refill time is the most direct and effective indicator for this purpose.
