Canine Vaccinations - what you can do:
Be an informed and responsible pet owner. Do your own research.
Ask your vet about having a titer performed for your Chinook(s).
Keep accurate records of the dates and the vaccines that your Chinook has been vaccinated with, the location of the vaccination, as well as dates and results of titers done.
After vaccinating, watch for any adverse reactions and report them to your vet (and if applicable, to the vaccine manufacturer) asap!
Notify your breeder of any vaccine reactions your Chinook may have experienced.
