Frequently Asked Questions
What causes mold and mildew in outdoor kennels?
Mold and mildew need moisture, organic material and limited airflow. Wet bedding, standing water under or inside the kennel, condensation on walls, and infrequent cleaning create the ideal environment. Blocking moisture at the floor, improving ventilation and removing soiled bedding quickly are the core preventive steps.
How often should I clean and dry kennel bedding to prevent smells?
Clean up urine or feces immediately, wash liners or bedding at least once a week for regular use, and more often if your pet soils them. After cleaning, fully air-dry bedding or use a dryer if the material allows; residual dampness is a common source of mildew and odors.
Are waterproof liners enough, or do I need an insulated house?
Waterproof liners stop liquid from reaching floors and reduce odor and mold risk, which is usually sufficient for crates and indoor/outdoor wire kennels. For permanent outdoor shelters exposed to rain, ground moisture and temperature swings, an insulated house with a raised floor provides better long-term protection against condensation and mold.
