All I do with Furgos is take him in the school and teach him basics, not like sit and stuff :) Walk, stand, walk stand. I put some poles on the floor and he trots over them. Skye is still a baby, as is Furgos and I believe that they should be allowed to be babies, so whatever you do make it fun for him.
Sometimes Furgs and I just literally chase each other round the field like mad men, he loves it though and I need to lost weight so we both get something out of it. :P
