The Centers for Disease Control and Prevention (CDC) regulates dogs imported into the United States to ensure they appear healthy, and are fully vaccinated against rabies. CDC staff review dog importations at 16-international airports. At other airports and land borders, CDC works with Customs and Border Protection (CBP) officers, who inspect the imported dogs to make sure CDC’s requirements are met. While still at other airports and land borders, CDC partners with CBP Agriculture officers, who inspect these animals in order to ensure CDC’s requirements are met. Making an assessment of this dog’s dentition, here, a CDC Quarantine Public Health Officer was verifying that a puppy was too young to be fully vaccinated for rabies, at the Seattle-Tacoma International Airport in Washington State. The picture, captured by Jennifer Cockrill, was an entry in the 2016 CDC Connects, Public Health in Action Photo Contest, in the category of Programs-Domestic.
