We know dogs can’t resist a good romp in the rain! Our waterproof liners are designed to fit over our dog bed cushions to provide protection between your cushion and the cover. The waterproof liner protects your dogs bed cushion from liquid, dirt, pollen, pet dander, dust mites and musty wet dog odors (we’ve all experienced it!). The waterproof liner is made from a 100% eco-friendly waterproof fabric that is tested to remain supple and impermeable after more than 300+ washing. The liner zips off for washing and can also be wiped clean with a sanitizer. We recommend purchasing this cover to protect and prolong the life of your cushions.
