Pet food, water removed
Label percentages include the water. Take it out, and a tin and a bag stand on one scale.
A tin says 11% protein. A bag says 30%.
With the water out, the tin has more.

The Guaranteed Analysis is all this needs — no barcode, no ingredient list, no brand. Six numbers off the tin and it goes on the shelf beside the others.
You'll see what we read and confirm it before anything is kept. With no barcode there is nothing to file it under, so it stays on this device and answers the question for you.
