Best Plastic Covers for Dog Beds: Waterproof Liners and Covers
The right plastic cover or liner can protect a dog bed from accidents, spills, and messes while extending its life. This guide highlights five reliable options that fit common 36- to 42-inch beds, focusing on waterproof protection, ease of cleaning, and durability. Each product is evaluated for compatibility with liners or outer covers, and practical notes are included to help you choose the best fit for your dog’s needs.
| Product | Type | Size | Key Feature |
|---|---|---|---|
| EechicSpace Waterproof Liner (36 x 27) | Liner | 36 x 27 | Full wrap zipper; waterproof outer layer; not chew-proof |
| PAWFINITY Waterproof Cover (35 x 22 x 3.5) | Cover | 35 x 22 x 3.5 | Full coverage; machine washable; durable Oxford fabric |
| Panabana Waterproof Liner (36 x 27) | Liner | 36 x 27 | Waterproof with full wrap zipper; reusable |
| EechicSpace Liner (48 x 35) | Liner | 48 x 35 | L-shaped zipper; easy on/off; water resistant |

When selecting a plastic cover or liner, consider fit, sealing capability, and how you clean and maintain the material. If your dog tends to scratch, opt for tear-resistant fabrics; for potty training or senior dogs, a fully waterproof barrier helps keep the bed dry. Always verify the exact bed core measurements before purchase to ensure a snug, protective fit.
EechicSpace 36×27 Inch Liner With Zipper

This liner is designed to fit a 36 x 27-inch bed core and features a waterproof outer layer with a full-wrap zipper for secure closure. Made from 100% polyester and plastic, it provides a protective barrier while allowing for straightforward washing. Note that it is a liner, not a complete cover, and is not intended for chewers. The design may trap a small amount of air, so leaving some space near the zipper is recommended to reduce firmness.
PAWFINITY Waterproof Cover for 35 x 22 x 3.5 Inches

This 35″ by 22″ by 3.5″ cover offers full coverage with a waterproof coating to prevent liquids from soaking through. It’s designed for indoor or outdoor use and is easy to clean. The durable Oxford fabric resists tearing and chewing to extend bed life. It’s machine washable and maintains its waterproof performance after multiple washes, with minimal wrinkling or fading.
Panabana Waterproof Liner 36×27

This liner uses a water-resistant coating to guard against urine and liquids. It’s a practical replacement that keeps the inner cushion clean while being easy to wash. The design features a full-wrap zipper to protect the inner foam, making it reusable and cost-saving. Confirm the bed core size to ensure a precise fit for your pet’s bed.
EechicSpace 48×35 Inch Liner for Crate Beds

This liner fits larger 48 x 35-inch beds with a durable, lightweight fabric. It uses a waterproof design and an L-shaped zipper for easy on/off. A noted disadvantage is that it can trap air, so users are advised to create a little space near the zipper. It’s easy to clean and suitable for repeated use, though not designed for chewers.
PAWFINITY 41 x 27 x 4 Inch Cover

Designed for XL beds, this 41 by 27 by 4-inch cover uses a durable, pet-friendly waterproof coating to seal out liquids. It’s easy to wipe clean and resists staining after multiple wash cycles. The cover’s Oxford-style fabric provides durability against daily use and protects the underlying mattress core from wear and tear.
Buying Guide: Key Considerations For Plastic Covers And Liners
Fit matters most. Always measure your dog bed core accurately, including length, width, and depth, to choose a cover or liner that fits snugly and prevents shifting. Consider whether you need a liner (protects the inner core) or a full cover (protects outer surfaces) and how often you’ll wash the piece. For households with puppies or dogs prone to accidents, opt for waterproof, tear-resistant materials and sealed seams. If your dog is a chewer, choose reinforced fabrics that resist punctures and tearing. Ease of cleaning is another factor; machine-washable options save time and maintain hygiene. Finally, assess how air might accumulate near zippers and plan for space to prevent stiff or noisy closures. A combination approach—liner for core protection plus a waterproof cover for the outer shell—can offer robust protection with easy maintenance. Different bed sizes require different fits, so always align product dimensions with your bed’s measurements to ensure a secure and comfortable fit for your pet.
