Transcript for Concerned Parents Hire This Guy to Sweep Kids' Rooms for Drugs
Every parent worries for their child's well being. Chief among the concerns is keeping them off drugs. How far would you go to keep tabs on your child? Some parents are taking it to the extreme with a four legged foot soldier in their personal war on drugs. Reporter: It's a quiet afternoon on the outskirts of New Orleans. All right. Reporter: But it's about to be disrupted. Michael Davis is on his way to execute a particular kind of drug bust. You ready? Reporter: The target, no hardened criminal. I want them to be afraid. Reporter: At 12, Jarod hasn't even reached high school yet. It's heart breaking. Reporter: But his mother fears her son is already using drugs. So she's taking what some might see as an extreme tactic. Let's do it. Everything has spiralled out of control. It keeps me up all night sometimes. I think about them and I remember when they were these tiny little babies in my arms, and then -- Reporter: She's reached out to this man, Michael Davis is former military who has had his own past struggles with substance abuse. His privately strained drug sniffing dogs, modern mercenaries in the war against drugs. Hired by anxious parents across the country to snoop on their own kids. His controversial approach, cutting law enforcement out of the equation entirely. There's nothing wrong with a proactive approach. It's good parenting. Search. Find me something. Come. Come. Here. What about there? You can move it. Please do. Do you mind coming down here and talking to me for a second? It sounds like you are into a lot of things that older people do. What's wrong, bud? You okay? Reporter: Confronted for the first time, he dissolves into tears. That's the first time he's cried in two years. Reporter: Is it out of the ordinary to find kids doing drugs in middle school? There are children 10 years old that are being put into facilities and 12 year-year-olds who have overdosed from finding drugs. Reporter: It plagues the nation, 50% of kids say they've tried drugs by age 18 and studies show that nine out of ten adults with substance abuse problems started using before age 18. Good job. Reporter: Fueling a market for Michael's unique business model. Are you ready to work? Reporter: Come critics argue it's profiting off parent's fears. We most often see heroin, meth, but we've also come across a lot of synthetic drugs, spice, spice is everywhere. Reporter: What he callings his worried parent program starts at $99. The dog can catch the scent of the narcotics from 25 yards away. Reporter: Outside of Louisville Kentucky, Davis's dogs are trained to identify chemicals used to process drugs, fertilizers in marijuana and compounds in meth and heroin just like police dogs. Good dog. Good job. Reporter: But there are no cops here. In fact, Michael guarantees absolute discretion. Everything is confidential. As we say, no police, no questions, just answers. Reporter: You're actually offering a comprehensive set of services. Yes, ma'am, that we locate the narcotics, provide advice on where to go, how to get help. Reporter: Some question if it's taking the law into your own hands. Reporter: Why does law enforcement see what you're doing with suspicious? They see it as stepping on their toes. We Tant to help the issue, locking up a child does not help the issue. Reporter: But two searches like these invade a young person's privacy? Could it backfire because it's a confrontational device? I think it could lead to trust issues, and it could also lead to difficulties having a positive relationship with your child. Face federal drug charges. A major drug bust. Reporter: Heroin and meth is trafficked throughout the country, cities like Louisville along the drug routs, plagued with narcotics. Michael says some of his biggest clients, halfway houses where past drug offenders have routine access to street drugs. We almost always come up with everything. You're dealing wan environment of drugs. It's what they know. We'll start here. Reporter: His dog hits on a locker almost immediately. That's a good girl. Reporter: And another. How about here? Reporter: She picks up scents in locker after locker, even the tiniest trace of a substance or fumes caught in clothing fibers can set her off. We'll test anybody whose locker was hit on by a dog. We wanted to send a message that we are going to be on top of this. Reporter: They often mind more than a trace. Meth pipes, crack pipes. They don't have anything else to smoke on, the user will take one of these. Reporter: Even crack residue. To help kids stay out of places like these, Michael finds himself in neighborhoods in suburbs talking to concerned fathers like this man who asked his not to show his entire face. We thought it was getting out of control. So we've called Michael, because we want to be sure of what is or is not in this house. Let's see what the dog finds. Reporter: He called Michael after he found his son incoherent. I stepped in front of him. He kind of looked at me and really didn't say anything. He didn't know who I was. Reporter: This father said he's worried his son is throwing his future away. They're driven by a crippling fear. Death. Our son could kill himself by mistake. You ready to work? Oakley to going to sniff your home. We're going to go upstairs and let her do her thing. Reporter: While their son is at work, Oakley works his bedroom. This is a sit down indication. Reporter: And there it is, a hit. That means he's 100% positive. She's pulling. She's showing you that there is signs of marijuana in this drawer. I would look in things like altoids cans. There you go. There it is. Pull it out and -- I don't want any pills in there. Reporter: The parents say weed is not surprising, but there are prescriptions too. These are pain pills. That is $100% hydroco-done. It looks like a xanax. Reporter: And a scale. I've never met a child with scales that wasn't selling. Reporter: A job well done for Michael's dog? A parent coming face to face with an ugly truth. Stop fighting him, become his ally and say I realize your issues. Let's channel them. I found a lot more than I expected. It's given me a lot more insight into probably what we need to do and how we need to proceed from here. Reporter: A problem another parent fears she's about to face. Jarod's mother awaits the results of the search. After sweeping every room, this search comes up empty handed. Every room in your home is clear of narcotics. Thank you so much. Reporter: Mom breathes a sigh of relief. I am very relieved. Reporter: In this business, these are perhaps the happiest customers. I'm proud of you. Thank you. And I'm sorry. Okay? You forgive me? Uh-huh. You know I love you, right?
