I think with it being unknown is the most unsettling at this point. They just do not know and is better to be safe. Me and the group of walkers at our local Shelter have stopped walking the dogs for a few weeks. Many of us have dogs at home and the some of the Shelter dogs are exhibiting coughing etc signs but since there is no definitive way to diagnose between just the flu or this, makes it hard. Keeping up to date on things from the kennel techs and my vet.
