My pup Abita is a big brain. But not really. I once was training her to stand next to me while on walks and never wander off. So she followed like I said... but didn't move when a tree was in front of her. It reminds me of World Of Warcraft following mechanics-she kept on moving, and never stopped... even in front of trees. Or she would be chasing my German Shepherd, Nala, and bump her head on a table, then do it again, and again, and so on. big brain abilities.
