Kennel cough is very, very contagious, but luckily not serious for otherwise healthy dogs. My vet described it as more of a pain for the owner than the dog, since they sound awful, but aren't really that sick! I'm glad you got the meds. Dolly just ran her course (she picked it up at Petsmart), and was fine in a week. I looked into the vaccination, but it's sketchy on how well it works, and she isn't around a lot of other dogs, so we didn't get one. My other two caught it from her, but as I said...they were fine in a week. It was sort of pathetic...lots of sneezing and coughing for a week!
I'm glad she is so much better!
