Could I Have Brought Home The Kennel Cough Virus?

I doubt your dog would get kennel cough without having direct contact with the puppy. Is you dog up to date on all vaccinations including kennel cough? If so then your fine. Just in case I would wash your clothes and spray your shoes with antibacterial. The best bet would be to call the vet, but if you don't want to, I would say just keep an eye on your dog to see if he/she changes. If you want to know more about kennel cough google it. But I think your dog will be fine.
