The Oklahoma City Animal Shelter has been closed for a third time this year to prevent disease from spreading from the shelter to other dogs in the public.Shelter officials said in a news release that the latest closure is because of an upper respiratory infection. The shelter's veterinarian noticed an increase in upper respiratory infections among the dogs and sent samples to a lab.About 65 dogs have symptoms, according to shelter officials.The shelter veterinarian and staff are working on a plan as they await the lab results; however, they suspect the canine flu is spreading through the shelter again. It's the same virus that closed the Oklahoma City Animal Shelter on March 29 and June 3 and other OKC metro-area shelters in recent months.The staff is treating the infected dogs with antibiotics again, the news release states. People who adopted dogs from the Oklahoma City Animal Shelter last week should monitor their dogs for upper respiratory-type symptoms such as a cough and runny nose. They also should seek medical advice from their veterinarian if any symptoms develop.Oklahoma City Animal Shelter Superintendent Jon Gary said in the news release that more closures are expected until immunity is built back up in the dog community.Top Headlines Frustrations run high after OKC venue closes despite customers having bookings Screen time linked with developmental delays in toddlerhood, study finds Oklahoma school districts shift gears due to extreme heat
