The simple answer is ... some do and some just don`t. lol. Ithink Stig started lifting his leg around that age, but only when theres a tree, a bush, or a rock around. But if theres only grass, he`ll still squat.
Gucci started at 4 mos. I think it's because he watches my 93 pound American bulldog do it. He sometimes goes too far and tips over. I got such A kick out of it at first I took a video. Then thought that was strange haha
oh poor Vagas.... the thing with Walter is when ever we take him out he never pees outside and only poos when we go on the beach. so when hes in our garden he goes on the grass never pees up my flower pots......i might have to run out and cock his leg up for him
