9. Attract attention
If you have fallen and cannot move, the service dog will bark noisily to get the attention from passersby. Some service dogs are so smart that they can open doors and go outside, trot over to the neighbors and alert someone to your problem. Radar, a white German Shepherd, would open the front door every day and walk the owner to the mailbox. Once, when the owner fell, Radar barked over to alert passersbys. Someone came, and the lady with fibromyalgia was quickly rescued.
