pH pH

The acidity or alkalinity of urine is usually measured in dog and cat urine by using test strips but more accurate results can be obtained by using a pH meter. The normal range for the dog and cat is 5.5-7. Urine pH is diet sensitive, with high protein rations causing an acidic urine. In the post-prandial period following a meal there is an alkaline tide during which the pH becomes less acidic. Table 10.6 lists the causes of abnormal urine pH.
