Dehydrated food is less processes than most canned foods, and obviously much less than dry food. As far as feeding goes, it’s fed about the same as any canned diet, in a higher volume than dry.
It’s a good choice for dogs that need a less processed and/or more limited diet (you can buy pre-mixes where you add your own protein source).
And both canned and dehydrated are better for adding water to the diet. They are more species appropriate, due to the water content.
About the only down side is cost, but small dogs aren’t very expensive to feed.
