After Gwinnett County’s animal shelter closed its doors this month because of a pneumonia-like illness that killed one dog and infected many others, local shelters are taking steps to prevent the same fate. Julie Edwards, executive director at the Humane Society of Northeast Georgia in Gainesville, said a clinical team quickly got together to write out the protocols they would take in case of the disease’s spread. The Gwinnett shelter closed April 10 after one dog died and 23 were experiencing symptoms including coughing and sneezing.
