Momo was neutered & he was jumping the day he got home...he loves to jump. No doesn't work for him, I never crate trained my babies, so that was out of the question. What worked was keeping him out of any room(s) that had furniture where he can jump onto. I also tried hitting the couch, like pounding on it & yelling 'NO! NO!' (saw this on It's Me or the Dog), he looked at me like 'HUH?' & didn't jump on it...for awhile. I think his attention span is very short. I wasn't much help, but hope you'll get somethin out of it.
