NASCAR is known for high speed, high octane excitement, but behind the scenes it is also a tightly knit community of drivers, their families and crews, and, of course, their pets. Cesar heads to the track at Daytona International Speedway, making a brief pit stop in Port Orange, Fla. to meet Brian Sacks and his Pekingese, Gizmo, a little dog that has everyone running scared due to his aggression and possessiveness. Cesar then visits the Halifax Humane Society, a grant recipient of the Greg Biffle Foundation, with Biffle himself and his wife Nicole. Finally, Cesar stops by the motorhome of NASCAR driver Kevin Harvick and his wife DeLana to help get their Chihuahua, Lo, who barks at everyone and snaps at people who try to pick her up, in line before they welcome their first child later this year.
