 Thickness has been spreading through several Delaware animal shelters. Kettle cough, or canine infectious respiratory disease complex, has impacted operations at several facilities, and the Delaware Department of Agriculture has put a temporary hold on importing and exporting of shelter dogs to and from other states. Also, due to strain at local shelters, the Delaware Office of Animal Welfare is requesting that all attempts be made to reunite any stray dogs with their owners before contacting OAW for a pickup.
