Drop in visit~ How do you get a dog in the crate without pulling them?

This pup's parents are out of the country. She puts her brakes on when she is on walks and when she has to go back in the crate. I was told she needs to go back in the crate each time I come because she is destructive when given free roam. The problem is she refuses to go into the crate and is a pretty heavy girl. I don't want to pick her up because she is snappy. She is in her harness full time so I have tried pulling her gently but she digs her claws into the floor and sits. I have tried treats, kisses, even crawling on the ground with her. She eventually gives in but it takes at least 15 minutes to finally get her to move. I don't want to drag her, or pick her up. Her folks aren't able to check the rover updates but I have notified them on each card her not wanting to get back in the crate. Any other ideas? Bringing a kong with treats from my girls tonight.
