When homeowners suspect mold in their house, many turn to unique solutions — including “mold dogs.” These trained canines are said to detect mold behind walls, under floors, and in hard-to-reach areas using their heightened sense of smell. But are mold dogs legit? Do they provide reliable results? And how do they compare to a more direct, lab-backed option like MycoTest’s DIY mold testing kits?
Let’s break it down.
What Are Mold Dogs?
Mold dogs are specially trained to sniff out the scent of microbial volatile organic compounds (MVOCs) — the gases produced by actively growing mold. In theory, their training allows them to alert their handlers to areas of hidden mold, even if it’s not visible.
While this sounds impressive, there are some key caveats.
The Truth About Mold Dogs
While some mold detection dogs may be well-trained, there’s no standardized certification, no regulation, and no peer-reviewed scientific consensus that mold dogs provide consistent, accurate results. Several concerns have been raised:
-
False positives: A dog may alert to mildew, moisture, or even unrelated smells — not necessarily active, harmful mold.
-
Handler influence: Dogs are highly attuned to their handlers' cues. Subtle body language or verbal prompts can unintentionally guide a dog’s behavior.
-
No data or proof: Unlike a laboratory analysis, the dog doesn’t provide numerical results or a written report. It’s subjective — based on interpretation.
What Happens After the Dog “Finds Mold”?
Here’s the key issue: even when a mold dog “alerts” to a possible mold location, that’s only the beginning.
The next step is almost always professional mold testing, which involves collecting samples and sending them to a certified lab for analysis. That means:
-
Delays while scheduling testing
-
Additional service fees
-
Lab processing costs
-
More time before you get answers
In many cases, by the time everything is said and done, you’ve spent hundreds (if not thousands) more than you would have with a more direct approach.
