Please read the following from their website...
The WATCH D.O.G.S. program was created by a group of dads in 1998 as a response to a similar elementary school tragedy. And although having dads volunteer at schools does provide extra sets of eyes and ears, the real benefits go far beyond any potential impact on security.
We've heard over and over that having WatchDOG dads in schools brings a calming presence to classrooms and hallways. Dad-volunteers are also able to assist the important work of educators and encourage numerous children during their time in the schools. (And WatchDOG dads will tell you they get more out of it than the kids do!)
School tragedies motivate concerned dads to take action, and WATCH D.O.G.S. provides one great way to make a positive contribution to the school environment.
Dad, if you're looking for ways to make a difference where you are, I hope these thoughts are encouraging for you. You can have a powerful influence in your community, your neighborhood, your child's school, and especially your home.
