I would expect to see this infection moving thorough groups of dogs until a large percentage gets infected and there are a lot of immune dogs.

I sit here and field 20 or 30 calls every few hours. Every coughing dog out there is not canine flu.

What we seem to be seeing is a virus that’s spreading fairly rapidly, particularly among groups of dogs in kennel and boarding situations.

One hundred percent of dogs will be susceptible.

That map should expand . . . by the end of next week.
