[Editor's Note: A few days after Karen posted this blog about parents fighting against dogs in schools, the Star-Telegram  reported on the big success of therapy dogs at a Fort Worth elementary school. The reporter's timing was perfect.]
What constitutes a service dog? Is it the old-fashioned definition of being a guide dog for a blind person or are we as a society ready to wholeheartedly expand our definition to dogs who alert people with diabetes or epilepsy to impending problems, dogs who provide people with emotional stability that they cannot achieve on their own, dogs who support people physically in case of loss of balance, dogs who protect impulsive children from running towards the road or other perilous situations and dogs who allow children to handle school when they might otherwise be incapable of doing so?
How do we distinguish between service dogs and dogs who are merely helpful but not in any official capacity?
