Can Mold Affect Pets?
The dog is not a mold test, but the dog does live on the floor.
Why this question keeps coming up
People notice the dog before they notice the wall. Then they ask the radon company to interpret the dog. We will not.
What it looks like in York County
Basement dog beds on damp carpet are common in ranch houses around York. The bed is the sampler. Wash it, and do not put it back until the carpet is gone or the slab is actually dry.
What to do
- Move pets out of musty rooms.
- Wash bedding.
- Fix humidity and leaks.
- Ask a vet about the animal.
What makes it worse
- Buy a pet mold supplement as the repair.
- Use ozone or foggers with animals in the house.
- Assume scratching proves a species.

These pages are homeowner education from Radon Mitigation of York, written by Dave Kessler. They are not a medical diagnosis, a species identification, or an insurance determination. Color does not tell you which mold you have. If someone in the house is sick, talk to a physician. EPA's homeowner guidance treats roughly 10 square feet as the line where many people stop DIY cleanup and call a remediation crew — sooner if sewage, HVAC, or anyone immunocompromised is involved. We are a radon and basement crew. When we are already under a York house we will tell you what we see and what we would do in our own place. We do not pretend a radon fan is a mold remedy.
