Mold inspectors using dogs can find hidden mold. Dogs are amazing animals, and their ability to use their sense of smell plays an important role in the detection of hidden mold. The fact is, dogs can detect mold in quantities that the average human might not even react to. By using dogs, inspectors can find mold hidden in hard to reach places like in the drywall or under floors. Dogs trained to find mold go through between 600 and 800 hours of individual training to accurately detect mold. A mold dog is trained to detect at least eighteen different kinds of of the most common toxic molds. If a dog alerts, there is a mold issue which signals a moisture problem, such as a leaky pipe. The reason this is effective is because mold spores have distinctive odors. A human may not be able to smell it, but the dog’s hypersensitivity to scent makes it the perfect mold detective. You should also know that this is not dangerous for the dog - that dogs have a unique ability to purge odors and other contaminants from their olfactory organs.
