Montana Mold Dogs was founded to bring the most accurate, non-destructive mold detection solution to families and businesses across the state. Our elite detection dog Rex delivers results you can trust — fast, clean, and without opening a single wall.
Rooted in Dillon, Montana. Professionally certified and field-ready.
Our Story
Founded in Dillon by Jess Reverie, Montana Mold Dogs was created out of a deep love for Montana homes and a frustration with traditional, invasive mold inspection methods.
Jess completed professional scent-detection training with Rex, including work with Bill Whitstine at Florida Canine Academy, before Rex earned full certification. Rex — a working-line German Shepherd — now serves homeowners, realtors, contractors, and property managers throughout Montana and nearby areas.
Montana Mold Dogs provides canine mold inspections. We do not sell, train, or place detection dogs.
Our mission is simple: deliver faster, smarter, and completely non-destructive mold detection so Montanans can protect their properties with confidence.
Why Mold Detection Matters: Health Impacts of Mold Exposure
Hidden mold can trigger real health issues — especially for families with children, seniors, or anyone with asthma or allergies. Early, non-invasive detection helps protect the people you love.
According to the U.S. Environmental Protection Agency and Centers for Disease Control and Prevention, molds produce allergens, irritants, and in some cases mycotoxins that can affect sensitive individuals.
- Allergic reactions — sneezing, runny or stuffy nose, red/itchy eyes, skin rash, and postnasal drip.
- Asthma & breathing issues — mold can trigger asthma attacks or worsen existing symptoms in people with asthma.
- Irritation — eyes, nose, throat, skin, and lungs can become irritated even in people who are not allergic.
- Higher risk groups — children, elderly, and those with weakened immune systems or chronic lung conditions may experience more severe reactions, including respiratory infections.

Note: Canine detection with Rex allows us to find hidden mold before it becomes a larger health concern — without any invasive damage to your home.
