(Reuters) - Testing of the mysterious respiratory illness affecting dogs across the United States has not yet revealed any new pathogens or any common cause for the wave of infections that have alarmed pet owners, the agriculture department said.

Instead, common causes of canine infectious respiratory disease have been identified in many of these cases through genetic sequencing of samples, the U.S. Department of Agriculture (USDA) said in an emailed statement.

The illness has sickened dogs in at least 14 states. It can last four to six weeks and cause mild bronchitis, which could escalate to pneumonia.

Respiratory diseases in canines can typically spread from dog to dog through direct contact or contaminated surfaces, according to the U.S. Centers for Disease Control and Prevention.

So far there is little indication the disease can spread to humans, but vets are warning dog owners to take extra care this holiday season, when pets travel with families or are placed in kennels.

Though cases have been reported for months, the American Veterinary Medical Association has stepped up its public advisories recently for the holiday season.
