Mayor Lorenzo Langford had ordered the patrol dogs off the streets last summer after hearing complaints from residents about how the animals were used.
But evaluations from outside police agencies found no problems with the dog handlers, and the animals returned to work on Saturday.
The patrol dogs - 15 German shepherds and Belgian malinois - handle a variety of tasks, such as finding missing persons and assisting officers involved in struggles.
Administration officials say the delay was worth it to make sure the dogs will be used properly. They note a new written use policy is in place to help monitor potential problems and promptly review them.
But police officials say the dogs were "sorely missed."
