"AFHV" goes to the dogs (literally) when the canine stars of "Beverly Hills Chihuahua 2" stop by for a visit with Tom Bergeron. Video highlights include funny Chihuahuas, including one who shows a German Shepherd who's the boss; cats, including a cat that's pestered by a backyard bird; plus animals that make strange noises.
