I want to sign my new 4 month old puppy up for a Canine Good Citizen class. The class requires proof of a rabies vaccination. I asked my breeder if it would be okay to vaccinate her before the recommended 6 months of age and she said she did not recommend it. Just curious to hear your opinions on the issue. I really want to put her in this class - but if the vaccine poses a health risk this young I will not risk it.
