I never mean to offend, but it would seem to me that 85 pounds is a bit heavy for a one-year-old dog unless she is really big-boned. Perhaps a bit of weight loss? You have a very good idea about starting her on low jumps; does she chase balls? It might be easier to teach her if she can chase her favorite toy over a low jump set so she has no choice but to go over. Just don't make it too low that she can just walk over it. We combine commands with our dogs, such as "come up" to get them to jump up into the car (although getting into the car is NEVER a problem -- getting them OUT is more difficult) . I'm not sure if she's lazy, but perhaps has never felt the need to jump -- so long as there is another way, so teaching her that it's fun and a great Mommy pleaser might give her more reason to do it.
