    We have a 5 year old Poodle mix that has been diagnosed with a liver shunt. As with most dogs with this problem, she is a very picky eater.
    The only food she will eat ongoing is Freshpet Homestyle Select Lamb in the tub. I am told it has 27% protein which is too high for her.
    How do I figure out protein %? If I add steamed vegetables to her food, does that lower the %?

    Hi Jazzyā€™s Mom ā€“

    To calculate the protein level of a food on a dry matter basis (the actual amount of protein) you want to do the following:

    1) Subtract the % moisture listed on the package from 100% ā€“ this is the % dry matter.
    2) Divide the as fed protein percentage found on the package by the % dry matter.
    3) Multiply this number calculated in step 2 by 100% to get the actual level of protein in the food.

    Youā€™ll notice that the more moisture the food contains, the greater the actual level of protein in the food is in comparison to whatā€™s stated on the packaging.

    Adding vegetables to the food would decrease the level of protein, however, Iā€™m not certain if you could add enough to get the protein where you need it to be without throwing off the nutritional balance of the food. No more than 20% of the diet should be unbalanced extras.
