Not a great time to be a greyhound owner, or a greyhound for that matter:

A mysterious respiratory disease is sweeping greyhound tracks across the country, killing dozens of dogs and forcing owners to halt racing as researchers hunt for a vaccine to control the outbreak.

Dr. Lisa Zerbel, a veterinarian in Massachusetts who is treating some of the sick dogs, said she thinks the illnesses are caused by a new strain of the influenza virus that is more virulent than the common one known as “kennel cough.” But other experts say it is too soon to pinpoint the cause.

I'll let the resident vet expert take a look at this one when we get home this afternoon.
