What Are Core Vaccines?

Core vaccines are those recommended for all pets regardless of lifestyle, geographic location, or breed. These vaccines protect against diseases that are widespread, easily transmitted, and can result in serious illness or death.

Unlike non-core vaccines (which are based on individual risk factors), core vaccines form the foundation of responsible pet ownership. At Paws Source, we strongly advise every pet parent to ensure their furry friend stays up-to-date on this essential schedule.
