It is my understanding that the period for Kennel cough is 3 to 5 days after exposure ? Is this what others believe ? This has been my experience the two times we have had it. Thanks for replys.

It depends on the strain most are 5-10 days after exposure. Also depends on dogs immune system.

Hope someone else chimes in. That is not what I just reread on line. Mine was 3 to 5 days. Dog had not been anywhere but that show.

The longest is 2 weeks from the end of coughing.

The question was how soon after exposure do they come down with it.

Just from my personal experience - as soon as 3 days and as late as 10.
