Dogs sit and stay to get vaccinated against parvovirus at San Francisco free clinic

Dogs lined up in San Francisco to receive free vaccines Monday to combat an outbreak of a highly contagious illness that can be fatal for some canines. The dogs got parvovirus and other vaccinations Monday as part of a joint effort by the San Francisco SPCA animal shelter, San Francisco Animal Care and Control and other organizations in the city's Tenderloin neighborhood. San Francisco SPCA Director of Community Medicine Programs Jessica Bogosian says parvovirus affects dogs' gastrointestinal tracts and is spread by dog-to-dog contact and contact with contaminated feces and environments. She says the important thing to know about parvo is that it’s almost completely preventable through vaccinations.
