Do not use a bumper when in the beginning stages of FF. Use a wooden dowell. You do not want the dog to associate any disscomfort or bad feelings towards a bumper. Bumpers mean fun time. Did you introduce your dog to the bench over several days prior to working him on that bench? Take a few days to introduce him to your table. Let him get up on it for a few minutes with you praising him then let him get down. I always teach hold on the ground. Be patient and consistant and you and your dog will get there. Have you considered letting somebody else do the FF for you?
