The canned food is very high in protein like drawlins was saying...
In order to compare the amount of protein in a canned food to a dry food, you have to look at them both on a dry matter basis....If a bag of dry food says 22% protein, and then you look at a canned and see 9% protein, that does not mean that the canned has less. You have to convert the numbers...
Take the amount of protein divided by the reciprocal of the amount of moisture and that gives you the amount of protein on a dry matter basis.
Example:
Let's say the canned food is 9% protein and it has 80% moisture....
Then take 9 (amount of protein) divided by 20 (reciprocal of 80-the amount of moisture) = 45% protein on a dry matter basis.
Now, you can compare the can to the bag of food. So, as you can see, the canned has 45% and the dry has 22%. Remember, this is just an example.
