The dogs got a bag of dried sweet potato for Christmas, so a couple days ago we figured we'd just try making our own. We let the sweet potato slices dehydrate overnight (from 6pm on Thursday to about 9am yesterday, so about 15 hours), and in the morning they were like this. I admit, they looked a lot more appetizing before they were dehydrated, but at least they'll last a while!
Today I'll be dehydrating beef for them. (The beef we got was nice because it was pre-sliced for Chinese fondue, so it's already thin enough to be dehydrated.)
