I don't blame you for being concerned....believe it or not a lot of vets are ignorant when it come to administering vaccines.....A combo shot is a huge no- no.....It not only contains components that are unnecessary but they also increase the incidence of adverse reactions, they over whelm the immune system and increase the risks for auto immune diseases, cancer, thyroid problems, etc. etc. in the years to come............
Dr Schultz is a leading researcher on vaccines , he does not endorse Kennel Cough, this is a self limiting illness and generally clears up on it's own in a few days....This is from Dr. Schultz.....
In an article from the October-December 2007, Vol. 26, #3 Journal of American Holistic Veterinary Medical Association, entitled Summary of a Presentation by Dr. Ron Schultz written by Patricia Monahan Jordan, DVM, it states that
"Kennel cough is not a vaccinatable disease, realize this and stop the boarding kennels from making the dogs sick."
Dr. Ronald Schultz declares in his An Update on What Everyone Needs to KNow about Canine and Feline Vaccination Programs" published in the 2008 Proceedings of the Annual Conference of the AHVMA, Pages 325-336:
"kennel cough is not preventable with vaccines."
This schedule is a good place to use when you need a guide on what vaccines to do or not to do, it is by Dr J. Dodds who is a respected researcher.....
Vaccination Schedule Recommendations For Dogs
Some good people to google about vaccines are.... Dr J. Dodds... Dr. R. Schultz.... Dr Pitcairn.....Catherine O' Driscoll.......
