Michelle, I also have used the cheap coffee trick with good results. DH drives a truck for a living and another driver told him he used a large can in his reefer to rid it of odors. Btw, if you can’t afford a crate right now, try this, worked like a charm when my mom did it a good 45 years ago. Attach the dogs leash to the doorknob, spread a thick layer of papers out no further than the dog can reach.
The dog simply won’t go. she can lay down etc, but she won’t mess on that paper. If you’ve been paper training her, she might a time or 2 but not after that.
