Unfortunatly dogs can get KC from a variety of agents.
The three most common pathogens are Canine adenovisrus 2 (CAV), parainfluenza virus (PIV), and Bordetella bronchiseptica.
You can also have other organisms involved as secondary pathogens.
I know that injectable modified-live virus vaccines against CAV2 and PIV are included in most combination distemper vaccines.
This is adequate for most pet dogs, but when a dog is boarding alot or in contact with other dogs alot, the risk of contracting KC can be elevated and the dog may benefit from a vaccine incorporating Bordetella bronchoseptica. Vaccines for Bordetella are available for parenteral or intranasal administration.
Hope this help, please consult your vet as regards the specific vaccines you are using as this is only general information!
