Organic fabrics are a good option for people and pets, because there are no pesticides or other toxic chemicals.
Stop Dog Urine from Ruining Your Mattress
We love our dogs, even when they pee in our bed. Hey, it’s part of life, but how do you protect your mattress so that dog pee doesn’t ruin an expensive investment.
One Drop of Liquid Can Ruin the Mattress
Any liquid can destroy a mattress, because the internal fibers are so highly absorbent. Once moisture seeps in it creates a breeding ground for bacteria, mold, and mildew. Which leads to unpleasant odors and potential health risks. And so far, we’re only talking about water. You can imagine the risks associated with people urine and pet urine. That’s why a waterproof layer is not just a convenience, it’s a necessity.

The Only Sure Protection Is a Waterproof Layer Over the Mattress
The only reliable way to protect your mattress from dog pee is by putting a waterproof layer between the dog and the bed. You can create a DIY protector from large, hefty garbage bags. Or you can purchase a waterproof mattress protector specially designed for bedwetting. It provides a physical waterproof barrier that prevents any liquid from soaking into the mattress. Keeping it dry and making clean-up fast and easy when your furry friend has an accident.
Choosing the Right Waterproof Mattress Protector for Bedwetting Pets
When choosing a waterproof mattress protector for a peeing pet, you’ll want to look for 5 key features. Make sure it’s waterproof, safe and non-toxic, fits correctly, comfortable, and easy to clean.
- Waterproof: Check the label to see that it’s waterproof. Avoid protectors that are water resistant or water repellent. Those protectors are good for a condition like night sweats, but they won’t block larger amounts of liquid concentrated in a small area.
- Safe & Non-Toxic: Waterproof mattress protectors have 2 layers. A top layer that’s soft and comfortable, and a second layer that’s waterproof. Organic cotton is a good choice for the top layer, because it’s free from pesticides and other toxic chemicals used during the manufacturing process. Polyethylene and TPU (thermoplastic polyurethane) are good choices for the waterproof layer. These two may not sound natural, but newer versions are derived from plant-based or bio-based ingredients like corn and sugarcane and they’re biodegradable.
- Correct Fit: A fitted style, like a fitted bottom sheet, with a tight elastic skirt will fit snugly over the mattress. Importantly, it won’t shift around while you’re sleeping which could lead to gaps where liquids could sneak through.
- Comfortable: While protection is key, you don’t want to sacrifice comfort. Choose a protector with a cotton terry top layer that’s soft and comfortable, and an ultra-thin waterproof layer that won’t make a crinkly sound when you shift in your sleep.
- Easy to Clean: Accidents happen, so choose a protector that’s machine washable and dryable. You might consider a back-up protector, so when there’s an accident you can strip the bed, throw the soiled protector in the wash, throw on the clean back-up protector, and get to sleep again quickly.

Frequently Asked Questions (FAQ)
1. Can I train my dog not to pee on my bed?
You can train a puppy not to pee on your bed, but with older dogs the underlying issue could be medical. Your senior puppy isn’t doing it on purpose, so training isn’t the solution. The only way to ensure your mattress is protected from pet accidents, coffee spills, or wine spills is to use a waterproof mattress protector for bed wetting and make sure the fit is secure.
2. Can a mattress be saved after the dog or cat urine has soaked into the fibers?
You can clean the surface of a mattress after an accident, but you can’t remove urine that’s soaked into the deeper layers. That’s why the manufacturer’s warranty is void after any accident or spill, even if it’s only water. One option is to enclose the entire mattress in an airtight zippered encasement protector to stop the urine smell from escaping into the air.
