A week after dozens of people adopted puppies featured in a local "Puppy Bowl," officials of the Indianapolis animal control agency that sponsored the event have reported that four of the dogs have the deadly canine parvovirus.

"This is not the warm and fuzzy thing you want to happen when people adopt from a shelter, but it happened," Media Wilson, spokeswoman for Indianapolis Animal Care & Control, told the Indianapolis Star. "We took all of the precautions we thought would prevent something like this from happening."

Wilson said about 50 dogs, most of them puppies, were adopted at the Feb. 2 event, modeled after the Animal Planet's annual program that features puppies frolicking on a miniature football field.

After the local event, Wilson said the agency began receiving reports that some of the puppies became ill. At least four cases of parvovirus have been confirmed, and one puppy has died.

The agency has sent letters to everyone who adopted a puppy Feb. 2 and offered to take back the animals and refund the $60 adoption fees.
