There are often queries around this subject after people have been to see the vet but want a little more background, the replies follow a similar pattern so it seemed sensible to write a synopsis that could be cut and pasted as an easy answer. Please feel free to suggest additions that anyone feels are appropriate.   Please note I'm not a vet and so the advice is from a layman's prospective and anyone not familiar with Kennel cough should seek a vet's advice at the earliest opportunity
