Oregon's Only Medically Aligned

Hi, I’m Susan Russell, founder of Mold Dog Knows.
I lived through mold illness myself, which is why this work is deeply personal. At Mold Dog Knows, we don't guess, we pinpoint. Our K9 teams are TRUE EXPERTS who are certified through AWDA, a valid 3rd party standard that verifies real accuracy -- because missed mold keeps families sick and false alerts costs thousands in demolition. AWDA certification is open to any team willing to meet this standard. This isn't about competition, this is about protecting vulnerable families and raising the bar for the entire industry.
We chose the harder path so you don’t have to, because you deserve to be safe in your own home.
Oregon is one of the wettest states in the nation. Rain, fog, and moisture make
mold incredibly difficult to control — even for diligent homeowners.

• Near-constant humidity along the coast and valleys
• Heavy rainfall saturating building materials
• Slow-drying attics, crawlspaces, and basements
• Moss growth indicating moisture retention
• Older wood-frame construction
• Poor ventilation in winter months
• Condensation issues in modern "airtight" homes
Even when a home looks clean and dry, mold can be growing inside:
wall cavities
subflooring
insulation
HVAC systems
attic sheathing
crawl space supports
This is why so many Oregonians experience chronic, unexplained symptoms.
