There's a coincidence--I just got back from the vet's earlier this morning having decided our lad might be coming down with kennel cough. The vet was of the opinion that he seemed well enough--no temperature, eating, playing, sleeping completely normally--but did notice that his lymph glands were slightly swollen, so we're home on R and R.
We discussed vaccine and she reckoned that, like the flu jab, it might help but it certainly doesn't guarantee protection against all the kennel cough strains that are out there. There is research suggesting that vaccinating repeatedly for kennel cough, as you might be forced to do if your dog went into kennels every year for his holidays, actually does more harm than good to your dog.
