When mixing in the greens and cheeses and supplements I have known a couple who used the canned food to mask those other ingredients so the dog would readily eat them, especially if the supplements were in powder form.

I couldn't say whether it was used more as a source of nutrition or more as the masking agent. That was a long time ago. I would imagine the moisture content would give it a leg up on its same name brand dry food counterpart.
