Too true that no two are alike! Here’s my donation: Teach a “step DOWN” cue, for instance, a gentle but clear tug on his tail when he is about to step on the ramp or anything lower than where he is. Teach a second cue for when his foot is about to touch solid/flat ground again (I tap the top of the butt). Have someone or yourself keep a hand on his hip to help keep him straight on the ramp and secure that you are there (he probably can’t see the ramp down and behind but he CAN see you on the side). Good luck, be patient and consistent, and be safe : )
Sure there's right and wrong but mostly there's just a whole lotta different.
