An appeal is being made by Notts police for young German Shepherd dogs to be assessed for a new training course starting in February.
The dogs will learn tracking, searching people and property, detaining offenders and crowd control.
Demand for police dogs is increasing and fully trained animals can cost as much as £1,000.
If the dog successfully completes the course, the police will pay the former owner £250.
The force is aiming to recruit German Shepherd dogs or bitches, aged between ten months to two years.
A police spokesman said: "The job demands so much from the dogs so they have to be good all rounders and capable of doing a multitude of tasks.
"The ideal type of dogs are inquisitive, playful especially with toys and slightly possessive. "
The course will last 13 weeks with each dog working with a designated handler under the directions of an instructor.
