Urine marking is a typical behaviour exhibited by dogs and cats where they tend to urinate certain places especially near vertical posts, trees and other objects.  They often prefer to lift up their leg and urinate, also known as raised leg urination (RLU). It is mostly seen in young intact male dogs. Females also exhibit this behaviour but quiet rare. Urine marking is distinguishable from normal elimination of the urine. In normal elimination, dogs tend to urinate till they empty the bladder which means there will be an increased volume of the urine and it takes much more time to finish the process.
