Quick Answer
Use a waterproof liner under your dog's bed cover to block urine, drool, and spills from soaking into the orthopedic foam, which keeps the bed hygienic and extends its usable life.
Why a liner beats a cover alone
A bed cover handles surface dirt and is easy to wash, but most covers are not fully waterproof. Moisture can seep through the seams and reach the foam core, where it creates odors and breaks down the support layer. A dedicated waterproof liner sits between the cover and the foam, acting as a second barrier that keeps the orthopedic structure dry.
This matters most for large dogs that are prone to accidents, drink a lot of water, or have drooling issues. Without a liner, you may end up replacing the entire bed—a more expensive fix than adding a liner from the start.
Choosing the right size liner
A liner only protects if it fits properly. A liner that is too small leaves foam exposed, while one that is too large can bunch up and create pressure points. Measure your bed's interior dimensions and match them to the liner size chart.
The 3 Sided Bed Waterproof Liner comes in four sizes—Medium, Large, XL, and XXL—so you can match it exactly to your 3 sided bed. Check the dimensions before ordering to ensure full coverage.
Diagnosing and Fixing a Wet Dog Bed
- Symptom: You notice a damp spot on the bed cover or a musty smell coming from the bed, even after washing the cover.
- Likely Cause: Moisture from urine, drool, or spills has soaked through the cover and reached the foam core, which is not waterproof.
- Corrective Action: Remove the cover and foam, let the foam air dry completely, then place a waterproof liner between the foam and the cover. Use a liner that matches your bed size for full coverage. Check the liner size chart and order the correct size for your 3 sided bed.
- When to Stop or Choose Another Option: If the foam is already stained, smelly, or loses its shape after drying, it may be beyond saving. In that case, replace the foam or the entire bed, and add a waterproof liner to the new setup to prevent a repeat.
