Little Brady Dunn probably doesn't know it yet, but his puppy,
Astro, is destined to become more than a best friend.  He might
become a lifesaver.  For now, the poodle/golden retriever mix is
Brady's new pet. But for his parents, White Sox designated
hitter Adam Dunn and wife Rachel, Astro is the newest option to
help keep things normal for their oldest child, who has
epilepsy.  Only 7 months old, Astro already is in training to be
a medical-assistance dog who will be 5-year-old Brady's
"shadow."
