I'd say Levi squats like a lady 80% of the time, does the half-lift 10% of the time, and total-lifts 10% of the time. He was in his first year of life -- not exactly sure how old, as I did not have him at the time.
He mostly does the total lift if he sees another pup doing it (copycat), or if he is outside and marking something especially wonderful. At parks and outside pet stores, he LOVES to lift his leg. If he is just trying to do his business, he squats.
