The ingredient list is of special interest to dog owners. Many look at
the first ingredient and if it's not a protein source like "beef" or
"chicken" they assume that the food is "low-quality."
They do this because it's exactly what some pet food marketers and
self-proclaimed pet food experts have taught them to do, even though
it goes against all nutritional common sense.
In fact, one popular pet publication teaches dog owners how to select
"quality" pet foods by comparing ingredient lists.
However, when tested, 23 out of 24 "Top Dry Dog Foods" had levels of
calcium that exceeded the maximum recommended level for an adult dog
and 19 out of 24 "Top Dry Dog Foods" had levels of phosphorus that
exceeded the maximum level for an adult dog.
When these and other nutrients are supplied in excess for an extended
period of time they could potentially initiate or complicate certain
medical conditions. These conditions include obesity, bladder stones,
kidney failure, skeletal disease, heart failure, hypertension, and
skin disease....
