Lolli does, in fact, know she can jump up on things. She just never does! haha
She is not a jumper. She jumped up on their 1 foot box once and I swear she couldn’t seem to figure out how to get down. But I know they don’t have the greatest depth perception and I was using a dark blue rug in their pen area so that is probably why. But she generally prefers all four paws on the ground until she decides to periscope and beg for treats. 
But last night, she surprised the heck out of my by jumping up on the couch. Again, she was treat motivated. No, I wasn’t holding treats or anything. They were both scampering around the couch, wanting treats. Lolli decided to hop on up to check things out and make sure there weren’t any up here. Also, as they know, if they do something cute, they get treats. LOL She didn’t want any touching of course, but she sniffed and looked around and then jumped down. It was just an unexpected visit and very cute! hehe
