Quick answer

For most large dogs, the Furhaven Quilted Waterproof Dog Bed offers the best balance of waterproof protection, orthopedic support, and affordability.

For senior dogs needing extra joint relief, the PetFusion Ultimate Dog Bed delivers thick memory foam with a waterproof liner.

What to consider for Waterproof Dog Bed For Large Dogs

Large dogs need ample space to stretch out, so measure your dog from nose to tail and add 12 to 24 inches for length. Waterproofing is critical for dogs with incontinence, heavy drooling, or who love water play. Look for a bed with a waterproof membrane or liner beneath the cover, not just a water-resistant coating. Orthopedic foam (at least 3 inches thick) helps support joints and prevent pressure sores. Removable, machine-washable covers simplify cleaning. For outdoor use, consider elevated cots that allow airflow and dry quickly.

What to look for in a comfort product (bed, pillow, blanket or house)

When choosing a comfort product for a large dog, prioritize size: the bed should be at least as long as your dog when fully stretched. Orthopedic support is key for seniors or large breeds prone to hip dysplasia; look for high-density foam or memory foam. A removable, machine-washable cover makes maintenance easy. For chewers, select materials like ripstop nylon or ballistic polyester. If using an outdoor dog house, ensure the bed is insulated and moisture-resistant to prevent mold and mildew.

Why this matters

Waterproof dog beds for large dogs often use a polyurethane laminate (PUL) or TPU membrane that is breathable yet impermeable to liquids, preventing moisture from reaching the foam while allowing air circulation.

The Options

Types Explained

Orthopedic Foam Bed

A bed with high-density or memory foam that contours to the dog's body, providing joint relief and pressure point reduction. Often includes a waterproof liner.

Best for: Senior dogs or large breeds with hip dysplasia or arthritis.

Elevated Cot Bed

A bed with a fabric sling stretched over a metal or plastic frame, allowing air to circulate underneath. It keeps dogs cool in summer and dry from wet ground.

Best for: Outdoor use, hot climates, or dogs that tend to chew traditional beds.

Bolster Bed

A bed with raised edges (bolsters) that provide head and neck support, creating a sense of security. Some have waterproof covers.

Key Buying Factors

Size and Dimensions

Measure your dog from nose to tail while lying down, then add 12 to 24 inches for comfort. Common large bed sizes are 36x48 inches or larger. Ensure the bed fits your dog's sleeping style: sprawlers need more space, while curlers can manage with a smaller area.

Waterproofing Type

Look for a bed with a waterproof membrane or liner between the cover and foam, not just a water-resistant coating. Some beds have a waterproof cover that can be wiped clean, while others have a removable waterproof liner. For heavy incontinence, a fully waterproof bed with a sealed zipper is best.

Orthopedic Support

Large dogs, especially seniors, benefit from high-density foam or memory foam at least 3 inches thick. This helps distribute weight evenly and reduces pressure on joints. Avoid thin foam that compresses easily, as it offers little support and can lead to discomfort or arthritis.

Ease of Cleaning

A removable, machine-washable cover is essential for maintaining hygiene. Some beds have waterproof covers that can be wiped down, but washing removes dirt and odors. Check if the cover is zippered and if the foam can be spot-cleaned. Avoid beds that are not washable.

Durability and Chew Resistance

If your dog is a chewer, choose beds made from tough materials like ballistic nylon or ripstop polyester. Elevated cots with metal frames are more durable than traditional beds. Avoid beds with exposed zippers or tags that dogs may chew. Consider a bed with a chew-proof warranty.

Living With It

Care, Cost and Maintenance

Washing the Cover

Remove the cover and machine wash on a gentle cycle with mild detergent. Avoid bleach or fabric softeners that can damage the waterproof layer. Tumble dry on low heat or air dry. Wash every 1 to 2 weeks or as needed.

Cleaning the Foam

Spot clean the foam with a mild soap and water solution. Do not submerge foam in water as it can break down. Allow to air dry completely before reassembling. For odors, sprinkle baking soda, let sit, then vacuum.

Maintaining Waterproofing

Inspect the waterproof liner or coating regularly for cracks or peeling. Avoid using harsh chemicals. If the waterproof layer degrades, consider using a waterproof mattress protector underneath the cover. Replace the bed if the waterproofing fails.

Pro tip

To extend the life of your waterproof bed, place a washable, absorbent blanket on top to catch dirt and moisture before it reaches the waterproof layer, reducing the frequency of washing and wear on the membrane.

Frequently asked questions

How do I choose the right size waterproof dog bed for my large dog?

Measure your dog from the tip of the nose to the base of the tail while they are lying down in their preferred sleeping position. Add 12 to 24 inches to that length to allow room to stretch. For width, measure from shoulder to shoulder and add 12 inches. Most large dogs need a bed at least 36x48 inches. If your dog likes to sprawl, go bigger. Always check the product dimensions before buying.

Are orthopedic waterproof beds good for senior large dogs?

Yes, orthopedic waterproof beds are excellent for senior large dogs. They provide thick memory foam or high-density foam that supports joints and reduces pressure points, which is crucial for dogs with arthritis or hip dysplasia. The waterproof layer protects the foam from accidents, which are more common in older dogs. Look for beds with at least 3 to 4 inches of foam and a removable waterproof cover for easy cleaning.

How often should I wash my large dog's waterproof bed?

Wash the removable cover every 1 to 2 weeks, or more frequently if your dog has accidents or is dirty. Spot clean the foam as needed. If the bed is used outdoors, hose it down and let it dry in the sun. Regular washing prevents odors and bacteria buildup. Always follow the manufacturer's care instructions to maintain waterproofing.

Can a waterproof dog bed withstand heavy chewing?

Most waterproof beds are not designed to be chew-proof. The waterproof layer is often a thin membrane that can be punctured by teeth. For heavy chewers, consider an elevated cot bed with a chew-resistant mesh fabric and a metal frame. Some brands offer beds with ripstop nylon covers that are more durable, but no bed is completely indestructible. Supervise your dog and redirect chewing behavior.

What is the difference between memory foam and bolster beds for large dogs?

Memory foam beds provide uniform support and pressure relief, ideal for dogs with joint issues. Bolster beds have raised edges that offer head and neck support and a sense of security. Some dogs prefer to curl up against bolsters. Many waterproof beds combine both: a memory foam base with bolsters. For large dogs, ensure the bolsters are high enough to support their head and not flatten easily.

Are waterproof dog beds suitable for outdoor use?

Yes, but choose a bed specifically designed for outdoor use, such as an elevated cot with a waterproof mesh sling. These beds allow water to drain and air to circulate, preventing mold and mildew. Avoid traditional foam beds outdoors as they can retain moisture and become heavy. If using a foam bed on a covered porch, ensure it has a waterproof cover and is brought inside during rain.

Do calming beds work for anxious large dogs?

Calming beds often feature soft, plush materials and raised bolsters that create a nest-like feel, which can help reduce anxiety in some dogs. However, they are not a substitute for behavior training or veterinary advice. For waterproof needs, look for a calming bed with a waterproof liner. The effectiveness varies by dog; some may find comfort, while others may not respond.

How do I prevent my large dog's waterproof bed from smelling?

Regular cleaning is key. Wash the cover weekly with an enzymatic cleaner to break down organic matter. Sprinkle baking soda on the foam, let it sit, then vacuum. Ensure the bed is completely dry before use to prevent mildew. If the waterproof liner is damaged, odors can seep into the foam, so replace the bed if smells persist.

What is the best sleeping position for a large dog on a waterproof bed?

Large dogs often sleep on their side or stretched out, which requires a spacious bed. A flat, orthopedic surface is best for side sleepers as it supports the spine. Curled-up dogs may prefer a bolster bed. Ensure the bed is large enough that your dog can fully extend without hanging off. For senior dogs, a bed with a slight incline can help with breathing.

A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
