SHE TRAINED HER DOG TO FIND WHAT DOCTORS COULDN'T

Your home can test “clean” for mold while hidden growth is still affecting your health.

Stacy from Moldpups joins Dr Daniel Pompa to explain how trained mold detection dogs can locate hidden moisture and mold behind walls, windows, and other areas standard testing may miss. They also discuss why mold sensitivity varies from person to person and how dogs, moisture meters, thermal imaging, and building experts can work together to find the source.

If you suspect mold but cannot find the problem, this episode will show you where to start.

SPEAKER_01 

My doctors are telling me I'm crazy. We'll come in and we'll find it. Sometimes a little bit of mold can take a person out.

Dr Pompa 

The level of sensitivity is everything. Only the dog would find these things. A lot of people are advertising mold dogs, but they're not certified. Gus was trained by the number one mold trainer in the world. I can't tell you how many homes we tested for people who were sick, and the homes tested fine with all the sophisticated mold testing available. And then we bring a mold dog in. And what do we find? Yeah, typically the problem. Well, guess what? We brought in Stacy from Moldpups. Hi. Moldpups.com. And she travels too, but you brought your dog in, and we found some things in this home. This is a new home, a two-year-old home. Okay, wouldn't have expected any problems. And by the way, every test that we've done in this home, because before I even bought it, I ran a bunch of tests. They came out spot on.

SPEAKER_01 

And that's pretty normal. Air tests, you're only getting a very small window of your home at that time. And you're running it for five seconds. The air conditioning could could affect it. There's so many different things. And I hear all the time you're not the first person. The air sample came back clear. But I'm I know there's something here.

Dr Pompa 

Yeah.

SPEAKER_01 

And my doctors are telling me I'm crazy. We'll come in and we'll find it. Okay.

Dr Pompa 

We'll know that. And Gus did. Gus found. Okay. First of all, this is an imposter. This is not Gus. This is dog, my dog Yankee, who wants to be a mold dog, I think, because he's been following around the house.

Why Certification And Training Matter

SPEAKER_01 

He loves me and wants to be a mold dog.

Dr Pompa 

So I think he has aspirations to be a mold dog.

SPEAKER_01 

Hey, if you want me to take him home, I will. We'll work on him.

Dr Pompa 

You know, first of all, I want to be clear on that joking note. A lot of people are advertising mold dogs, but they're not certified. Gus was trained by the number one mold trainer in the world. Absolutely.

SPEAKER_01 

So Bill Whitstein, who is I he started it 30 years ago with the military and has been a complete boss in the space. Yeah. Honestly, I've I've heard other trainers calling him trying to figure out what what his secret sauce is. Yeah. Um, and so Gus has been trained on 18 types of mold that's in the house making you sick. The wet and the dry molds. He's been trained on both. So he's not hitting on the mold. He's hitting on the MVOCs, the microbial, volatile, organic MVOCs, um, compound. So when he's smelling, he's not smelling the mycotoxins, he's smelling those MVOCs.

Dr Pompa 

Wow.

SPEAKER_01 

And when he sits, he's telling me it's right here.

Dr Pompa 

I I watch that. We'll we'll put some video in here because you know, watching him and they may be putting the video, watching him go around was remarkable.

Hidden Mold In A New Home

Dr Pompa 

The level of sensitivity stunned me. So we get some condensation when it gets really cold here on the windows, which many uh uh that happens in Utah when it's really cold in the mountains. Um moisture, it dries up uh in a few hours. But that moisture it it still causes some level of mycotoxin. Yeah. Dust was around those windows. I mean, he found it.

SPEAKER_01 

I mean, he did he was marking it pretty good.

Dr Pompa 

He was marking that's what we say, he's marking it. But we found, and you know, again, that probably wasn't an area of like major contamination, but he did find something that I had suspicion about. He found he marked an area in our shower that is also a steam room. And what I had noticed was is that where the steam comes out, it wasn't sealed correctly. Right. And I realized, oh my gosh, water even from the shower could have actually been getting down in there. So I dried it, you know, thinking maybe it was in there, then I sealed it. Okay. But Gus marked it.

SPEAKER_01 

He marked it pretty good.

Dr Pompa 

Yeah, he marked it pretty good. And you said that was a concern because you're like, he he didn't just mark it like he kind of did the window condensation. He he sat there.

SPEAKER_01 

He sat hard and he nosed it pretty hard. So I knew that there was going to be something there. And then when we pulled back the the cover to get in there and kind of look around, we found it.

Dr Pompa 

Well, then we but put a camera behind it, went where we can't see with the camera, and lo and behold, there was uh some black mold in there.

SPEAKER_01 

Yeah, it was definitely there. So the boroscope, I mean, you're not having to mess up too many things, but you're able to get in there and see what's going on, and that

What Gus Found In Another House

SPEAKER_01 

uh confirms Gus a lot of time.

Dr Pompa 

In what my son's house, you did my son's house, right? So a four-year-old home. You brought Gus in this home. By the way, two times it was tested with dust testing, ermie testing, and other air tests, tested okay. What did Gus find in my son's house?

SPEAKER_01 

He found he marked all over your son's house. Um the windows had failed. There were um issues with the uh fireplace, the chimney. Um, and when we would pull that back, uh the remediators would go deeper. Uh so a lot of times with Gus, I bring in and you have to bring in an IEP, and they will confirm him. They're going in, they're looking, they're pulling back those windows, and they're seeing a lot of air gaps, a lot of airflows coming in through those windows.

Dr Pompa 

Because they weren't sealed properly. They weren't sealed properly. So we have condensation. There he he lives in near Nashville, hot, cold, con it moisture.

SPEAKER_01 

Moisture, just moisture.

Dr Pompa 

So it wasn't like they leaked necessarily. They were creating condensation, which is moisture. Yeah.

SPEAKER_01 

And another area we found where um his shower, um, there was a scholuter system in there, but the grout had failed and there was water underneath and there was mold growing. Gus marked it.

Dr Pompa 

Uh Jonathan with JF Healthy Homes and uh And by the way, we're gonna talk to Jonathan next

Pairing The Dog With A Building Pro

Dr Pompa 

because bringing a mold dog in with a building biologist is the way to go. Right. Meaning I I wouldn't have been able to like, okay, there might be a problem in the shower, but having the building biologist follow right up.

SPEAKER_01 

That's what so the mold dog is not the end-all be-all. Right. It is the mold dog could be a problem here. Yes. The mold dog and the handler, and then you bring in someone that is investigating and you're looking for it. It's it's a really good combination. But it's not just you can't just have the mold dog. You've got to have the people that are gonna come in and look behind you.

Dr Pompa 

And Jonathan, who we're gonna talk to next, he he travels with you a lot on these cases, right? And um he also found something else. Wait till you hear this. But um, so that that combination is the key. You don't just want a dog, it has to be the right dog. And then with the building biologist who knows where to look, because then they're able to look and say, okay, you know, here's some of the suspicious areas and are they a problem or not?

SPEAKER_01 

Building biologists will go in and they just dig deeper, and it's fascinating what they can find. Yeah. And so working with him uh has been a really good, um, a really good thing for us.

Dr Pompa 

Yeah. So I think one of the things I learned with Gus was first of all, like

Sensitivity Changes What “Safe” Means

Dr Pompa 

even like the windows condensating. I mean, if if there's moisture, there's mold. But the question is, is it a level of mold that is a problem for a human? That's the question.

SPEAKER_01 

Now I'm gonna ask you, how sensitive are you to mold?

Dr Pompa 

I'm very sensitive.

SPEAKER_01 

Then I'm gonna say you're probably gonna want to take care of it. Yeah. Um so just a little bit of mold sometimes is not gonna affect hardly anybody. Sometimes a little bit of mold can take a person out. So it just depends on how sensitive you are. Yeah. Now, a lot of the time with some of the things I'm gonna tell you to keep an eye on. I'm not gonna tell you to the moisture meter, thermal imaging, and boroscope didn't show anything. Gus marked it and he is sensitive, so I'm gonna tell you to keep an eye on it. If you start seeing warping or discoloration, that's a problem.

Dr Pompa 

Yeah, that that steps over the line. And like my windows were constant, but it wasn't getting into the wood behind it or anything, which is another level of of problem. But but the level of sensitivity is everything. And I I've only the dog would find these things.

SPEAKER_01 

I I've learned only the dog.

Dr Pompa 

Yeah. Um I'm done with the other testing.

SPEAKER_01 

I kind of agree. Like the the air testing.

Dr Pompa 

Yeah, I'm done. Done.

SPEAKER_01 

But yeah.

Dr Pompa 

Yeah.

SPEAKER_01 

Mold dog is kind of where it's at. I mean, they're these

Where To Find Moldpups

SPEAKER_01 

dogs are just are sensitive and they they're gonna find the mold if they're doing right.

Dr Pompa 

You and Jonathan travel oftentimes. Tell them where to find your uh Gus.

SPEAKER_01 

You can find me on moldpups.com. Tell them mold pups on Instagram, you can find me on Facebook, just mold pups. We're there.

Dr Pompa 

So Yeah, Gus is amazing, by the way. Okay, so love Gus, love you. Yep, thank you. Wait till you hear what the building biologists found. It's not what you think.
