Pet owners across the country are on edge after last month's massive pet food recall but now, Michigan State University hopes to offer some comfort.

A team of doctors is conducting a nationwide survey to find out how many animals have died or gotten sick because of the contaminated pet food.

The MSU study is designed specifically for pathologists and veterinarians who come across sick pets.

"There are animals that are unfortunately dying every day from kidney disease. And what we want to do is make sure when we're trying to figure out what the toxin is that we're only looking at the animal that died from this toxin and not the animal that may have died from anti-freeze poisoning," says MSU veterinarian, Dr. Dalen Agnew

The online survey is scheduled to last at least a month and MSU hopes pet owners will find comfort in knowing the truth.
