Set your vegetable slices on a trays of your dehydrator.
Using your manufacturer's setting for vegetables cook for 2-4 hours checking for desired consistency. You want them to be chewy and leathery not limp or crunchy.
Take out the ones that are finished and keep the others in the dehydrator until finished.
Store in a ziplock back in the refrigerator for up to a week.
A reader gave me this tip: Store them in a paper bag. It helps them stay dry. I tried this and put them in the fridge as well. It worked well and the treats stayed crunchy (the way my dogs like them)!
