there was a thread on here with someone who had done this and there was a photo of it. does anyone know how i teach nelson to do that? i tried when he was really little and tried propping up inbetween a corner of a wall but he couldn't stay up there. i jsut assumed in the end that american bulldogs just can't do it but i'm sure the pic of the dog on this forum was an american bulldog too i think. so there must be anotehr way.
