Some service dogs are really unique. I watched a program last evening. A young lady has a condition where she can pass out without warning. This caused her to be house-ridden. She got a dog as a pet and it turns out her dog can sense an oncoming episode and she gets a 5 minute warning. She can now rejoin society. Until the dog dies. A clone and some socialized training with the first dog could enable her to continue being outside the house.
