I got my Oliver first, then my Brooklyn, Oliver has been such a good boy, no marking, whatsoever. He is the reason for Brooklyn! I had him fixed early, 5 mos. old and he never really learned the whole marking thing. As for potty training, he did great! Very smart boy. We did paper at first, then moved to outside, when the weather got warmer. Go for it, you wont be sorry! Good Luck!
