A PETCO survey finds just 10-percent of pet owners understand pet food packaging labels.

More than 80-percent are concerned about giving their animals nutritious food, with 31-percent saying this is "critical" and 52-percent calling it "important."

But, just 43-percent say they know which ingredients are most beneficial to their pet and which are simply fillers.

Only 39-percent understand how basic, premium, natural, and organic pet foods differ nutritionally.
