I am not sure if this will help any but... About 3 weeks ago Roxie got a nasal dose of the Bordatella vaccine. I wanted to get Roxie groomed for the first time and all of the groomers in my area require the Bordatella every 6 months. She received the Bodatella vaccine and a few days later I took her to get groomed at a very nice, clean pet resort & salon, that was highly recommended by a close friend. Needless to say Roxie ended up with Kennel Cough. I am not sure if it was from the nasal dosage or from the groomer
