What are non-core vaccines, and why does my puppy need them?

The non-core vaccines (at least the ones that we administer here) are leptospirosis and bordetella. We especially recommend the bordetella vaccine for dogs that go to dog parks or boarding facilities. That's for kennel cough, which is a respiratory condition. And then leptospirosis is a bacterium they can get out in the environment, especially around water, and that can really affect their kidneys. So we'll vaccinate against that.
