Mickey isn't like his brothers and sisters. They're stronger, faster, and they're definitely better when it comes to smelling. You see, Mickey's parents are dog nuts, and his "brothers and sisters" are their prize bloodhounds. Mickey eventually learns how to sniff out a trail as good as his siblings, and his parents have never been prouder. Life can't get much better, but it's about to get much worse. When a tragic accident leaves Mickey an orphan, he must leave his dog family behind to live with an aunt and uncle he's never met before. Even worse, they hate dogs and kids.
