The dog owner was astounded by the discovery, and said he believed the baby was just a few hours old since she was still warm and her umbilical cord was still attached.
Wilday called authorities and within minutes police and an ambulance arrived at the park.
BBC News reported the newborn was wrapped in a light blue blanket and was placed inside an Entertainer toy shop bag. The baby was taken to Birmingham Heartlands Hospital and doctors determined she weighed six pounds and is approximately one or two days old.
Police took the blanket and sent it to be processed for DNA. They hope the test results will help identify the baby’s parents.
The infant, now known as “Baby Jade,” was named after her four-legged hero rescuer.
“She is a hero dog,” said Wilday. “There was no one else in the park at the time and it was very cold. If it wasn’t for Jade that baby could have been dead.”
The baby was found in good health and is expected to make a full recovery. Authorities hope Baby Jade’s mother comes forward soon.
