WATERLOO, Iowa (AP) – Waterloo-area veterinarians say they’ve noticed an uptick in dogs suffering from an unknown respiratory illness. The Waterloo-Cedar Falls Courier reports that doctors haven’t been able to pinpoint the illness, but they say dogs respond well to antibiotics and cough suppressants. The symptoms generally pass after about 10 days. Doctors say well-vaccinated dogs suffer from a cough, but show no other signs of distress.

Dr. Tom Taylor of Den Herder Veterinary Hospital says about 25 dogs have been treated in recent days. Doctors say owners should avoid taking their pets to places with lots of other dogs for the next few days. In addition, pet owners who have been in contact with dogs other than their own should wash their hands and change clothes before touching their dog.
