Claudia Osborn MD & TBI survivor, has a wonderful web site.
In part of it she describes the assistance her service dog provides
her. Please visit Claudia Osborn. for more
Jack has a number of conditions and concerns as of
late, that a service dog would provide relief toward. For example,
on long driving trips - the dog could ensure he stay awake, and
not run off the road!

Among basic daily functioning tasks -assistance finding things,
assistance staying focused and out of danger, service dogs also
provide companionship, which is vital as so many TBI survivors feel
isolated and alone.

There are many Google links to service dog directories. Most directories
are easily managed - with links to each state.
