Wet dog food, a.k.a. “canned” dog food, is not nearly as popular as dry food. The total sales figure for dry pet food in the U.S. last year (more than $12.7 billion) was more than 21/2 times that of wet pet food (almost $4.8 billion). I understand the reasons for this, but wish it wasn’t so. Canned food is actually a much healthier diet for dogs than kibble.
