Service Dog Shows Up Alone, Woman Asks

When dogs are separated from their owners, it usually means they simply lost them and need to be relocated to their home.

But service dogs are trained to stay by the sides of those they are meant to help.

Service dogs, from the time they are puppies, are trained to help others in need. Their instincts are instilled for detecting danger and helping their owners.

When 20-year-old Tessa Connaughton from California fell face-first in a grocery store, her service dog knew exactly what to do.

Connaughton got her service dog named Raider, an English mastiff and bull mastiff mix, almost three years ago to help with her autism and seizures. When she needs pressure, he lays on top of her to calm her down.
