Great vaccine. To date, I have not had any reactions with this vaccine. Of course, if giving to an extremely tiny puppy, I administer Benadryl 30 min prior to vaccine administration as a safety precaution.

I breed Chihuahuas, Pomeranians and Yorkies.

We have been using these vaccine with our chihuahuas for 4 years. Never had any issues to date. We also use (FULL) vaccinations with our puppies.

This is the product I use faithfully. I start with the Duramune straight parvo vaccination and then 3 weeks later, I give this vaccine. No complaints here.
