Hi, Tena Louise...

The first service dogs I was ever aware of were the Seeing Eye Dogs. Now they are trained to be Hearing Dogs and Seizure Alert Dogs, too. But the latest I have been aware of are the large strong dogs being used to aid a person who may be occasionally wobbly ... or unsteady at times. Not so much that they need to tote an awkward heavy walker around for every last step, but perhaps that security as you step off a curb onto the street.

I think it is an excellent idea. I think that, depending on the height of a dog, a harness with either a close grip or the type of harness used by the blind - either can give that bit of steadiness. The dog would have to be strong enough to take some weight.
