I have 2 females that lift their legs to pee!!!!
They squat until they are almost done and then lift their left leg to finish the job.
Jazzy started to do this after watching her friend--a 90 lb male golden lab who lived next door. Mickey just followed Jazzy's example; per usual.
Not to be gross, but I am happy they pee like this. Their fur, in that area, stays much cleaner and odor free. If you know what I mean.
