I have a 4 yr old yorkie girl (peaches) and when she goes pee pee she always hikes her leg. She marks territory all the time and everwhere

Is this normal for a girl dog to be doing this I have never seen her squat to pee always hiking, and the marking territory well.......
Is there something that i can do or is this how she will always be like?? Im kinda worried about her Any advice would be great thanks in advance
