Prince George’s County Animal Shelter Identifies ‘Strep Zoo’ As Contagious Virus Spreading Among Dogs

The Prince George’s County Animal Services Facility and Adoption Center (ASFAC) has identified a bacterial respiratory infection, Streptococcus Zooepidemicus (Strep Zoo), spreading in dogs, leading to the temporary closure of the facility. Strep Zoo is highly contagious and often fatal in dogs if not detected early. While the virus has not affected cats or other animals in the facility, officials emphasize its danger in animal shelters with close contact and high stress levels.

Strep Zoo, primarily found in horses, cattle, and pigs, rarely causes disease but can lead to severe pneumonia in immunocompromised dogs. There is no vaccine, and warning signs are limited. The facility closed temporarily on January 4 due to the outbreak, implementing isolation, testing, and treatment for affected animals.

As of January 11, the facility remains closed for deep cleaning, and reopening depends on ten days without new symptomatic animals. Early detection allowed immediate actions to halt the spread, according to Associate Director David Fisher. Strep Zoo symptoms may mimic other illnesses, and ASFAC officials recommend seeking veterinary care for pets showing signs such as sneezing, nasal discharge, difficulty breathing, lethargy, fever, coughing blood, or vomiting.

Officials reassure that well-vaccinated, healthy dogs regularly visiting a veterinarian are unlikely to contract the disease, emphasizing the importance of preventive measures.
