Working, utility and assistance dogs
There are several types of working dogs:
* Assistance dogs which help the seeing and hearing-impaired. Others are trained to help those with epilepsy and psychiatric disorders, by detecting the onset of the condition so they can seek help. The typical assistance dog is a sociable breed such as a Labrador Retriever.
* The detection dog, which is a dog trained to and works at using its senses (almost always the sense of smell) to detect substances such as explosives or illegal drugs.
* Guard dogs are trained for personal protection, or to protect property. These are commonly Doberman Pinschers, German Shepherds and Rottweilers as well as dogs of other breeds that have protection instinct.
* Herding dogs can be trained to help the herder to move the herded animals, such as sheep. Australian Cattle Dog, Border Collie, and German Shepherd are common herding breeds.
* Hunting dogs can be trained to assist the hunter. Terriers and retrievers are hunting breeds.
* Police dogs, typically German Shepherds, are trained to assist law enforcement officers.
* Search and Rescue dogs also known as SAR dogs, are specially trained to search for missing humans. The archetypal breed is the St. Bernard.
