Tune in Tonight to "Animal Planet Investigates: Petland"
Looks like a worthwhile Animal Planet show tonight about Petland, the nation's largest retail supporter of puppy mills. Watch as Humane Society of the United States undercover investigator "Mike" sniffs out the scummy underbelly of this industry. You'd be wise to keep a Kleenex box nearby. Check it out at at 10 p.m. ET/PT.
