I gotta tell ya folks. I have used Intra Trac II for over 25 years and have NEVER had a dog get even a mild case of kennel cough. We have even used it to keep it from spreading in the kennel(we board). If a dog comes down with KC( which has happened a couple times) we just give every dog the nasal and BINGO it's gone. Just my experience.
