There are less reactions to the intranasal, no pain of a shot, and it offers protection faster than the injection.
Here is an article on the topic that sums it up. Kennel Cough (Infectious Tracheobronchitis) in Dogs |
Thanks for the link. Yesterday I was looking for more information and found this site:
Nasal or Injectable - Which Vaccine is Best for Your Dog? - Page 1
A new study indicates that intranasal should only be given the first time.
Quote:
Recent studies have questioned the effectiveness of the intranasal vaccine, especially when given to dogs that have either been previously vaccinated or have been exposed to bordetella. This recent study indicates that the nasal vaccine works well in a dog that has either never been vaccinated or has not had kennel cough. Future vaccinations should be injectable to provide protection.
Another disadvantage is there may be some side effects following the nasal vaccine. Sneezing, mild cough and fever may develop 1 to 2 days following vaccination and usually resolves in 3 to 4 days. Some dogs do not like having drops placed in their nose and will strongly resist.
Recommendations
Due to the recently published study comparing injectable and nasal vaccines, it is currently recommended that the injectable vaccine be given. If desired, the nasal vaccine can be given the first time, followed by the injectable vaccine for future boosters. For all vaccines, it is important to vaccinate at least 5 days before potential exposure. Vaccines do not work immediately. It takes time for the body to respond to the vaccine, develop immunity and provide protection against the specific disease.

I really wished I understood the need for boosters because this seems to be where we overdo things.
