I would think it would have to be the nasel version to help with that? I don't know and I personally don't know that it would do any good. Deb Paul adds... As another owner of a Boarding Kennel...Deb is too...I will add the nasal is superior to the sub Q injectible and the length of coverage is basically the same. Several years ago we mounted a campaign in this area to get local vets to change to the intra nasal. We have not had 1...(knock on Evans Mesquite Oak head)...case of bordetella in that many years. It takes effect much faster and impregnates itself into the mucous membranes that the bordetella infects first. We will be doing the same for all of the dogs we are taking to Concord this coming weekend. Paul ============================================================================ POST is Copyrighted 2005.
