(KRON) -- A lost dog in the North Bay had been treading water deep inside a well for at least two hours before she was found by an animal control officer who could hear her distressed cries, the Solano County Sheriff’s Office Animal Control said. Animal Control Services Officer Bradley responded Monday to an uninhabited home in Vallejo after receiving a report about a dog that may have fallen into a well inside. Shortly after, animal control received another call from dog owners frantically searching for their missing Fiona.
