Are Nylon Bones Safe for Puppies and Dogs?

Dogs chew. It's what they do. And nylon dog chews are one of the most common ways pet parents keep them busy. Nylon bones are tough, long-lasting and easy to find, which is why they end up in so many toy baskets.

But are nylon bones safe for puppies and dogs? Here's what nylon dog chews are made of, the risks to watch for, how to use them more safely, and what to look for in a nylon bone alternative.

What are nylon dog chews?

A nylon dog chew, often called a nylon bone, is a hard, non-edible chew toy made from nylon. Nylon is a synthetic plastic (a polyamide) that's generally made from petroleum and melted into shapes. Nylon dog bones come in many shapes, sizes, textures and flavors, and they're usually marketed for strong or aggressive chewers because they're built to resist wear.

Nylon chews are chew toys, not food. They're not meant to be eaten, and swallowed pieces aren't digested.

Are nylon bones safe for dogs?

Nylon bones can be part of a dog's chew routine, but they come with real risks. No chew toy is completely safe, and nylon's biggest selling point, its hardness, is also its biggest drawback.

Hardness and tooth damage

Many nylon dog chews are harder than your dog's teeth, and powerful chewers can crack or wear down teeth on them. The American Animal Hospital Association suggests a simple test for any chew: "Press your thumbnail into the chew toy surface. If you can't leave an indentation, the toy is too hard" (AAHA). Many nylon bones don't pass.

Sharp edges as they wear

As a nylon bone is chewed, its surface can become rough, with sharp bristles or edges that can scrape gums. Worn ends can also break off into hard pieces.

Swallowed pieces

Because nylon isn't digestible, swallowed pieces can cause choking or a blockage. If your dog swallows part of a nylon bone, contact your veterinarian right away.

Plastic that sticks around

Nylon is a plastic. Worn-off pieces are plastic, and a used-up nylon bone persists in the environment long after it's thrown away. That's why many pet parents look for a natural dog chew instead.

Are nylon bones safe for puppies?

Puppies have developing teeth and sensitive gums, so very hard nylon chews are usually a poor fit. Puppies also chew enthusiastically and are more likely to break off and swallow pieces. For teething puppies, choose a softer chew that's still too big to swallow. See our guide to choosing a softer chew for puppies.

How to choose a safer nylon dog chew

If you use nylon bones, a few choices lower the risk:

• Match the chew to your dog's chewing style. Gentle chewers, puppies and seniors don't need maximum hardness.
• Size up. The chew should be too big to swallow and too big to fit entirely in your dog's mouth. It's very hard to go too big and very easy to go too small.
• Try the thumbnail test. If you can't make a small dent, it may be too hard for your dog's teeth.
• Read the label. Check the material and whether the chew is edible or not. You read your dog's food label, so read their chew toy label too.

Nylon dog chew safety tips

1. Check the chew after every session

Look for rough edges, cracks and missing pieces. Replace the chew as soon as it's worn, cracked or small enough to swallow.

2. Supervise chew time

Stay nearby, especially with a new chew. If a piece breaks off, take it away right away.

3. Store chews properly

Keep chew toys out of direct sun and heat, and put them away when chew time is over.

4. Watch your dog's mouth

Blood on the chew, reluctance to chew or chewing on one side can mean the chew is too hard. Stop use and check with your vet.

A plant-based nylon bone alternative: BetterBone

We created BetterBone for dogs who love the durability of a nylon dog chew and owners who want a gentler, more sustainable option. It's a long-lasting chew toy made from plants instead of petroleum-based nylon.

• Hard density is our nylon alternative. BetterBone Hard is the density most similar to nylon: super durable and made for power chewers who tear through rope and toys. Not every dog needs that much. Moderate suits most daily chewers, and Light is made for puppies, seniors and gentle chewers.
• Flakes, not splinters. Instead of wearing into sharp edges, BetterBone flakes into small, rice-sized granules as your dog chews.
• Made from two plant-based materials. BetterBone is made with Vernovo, a blend of cellulose from tree fibers and plant extracts, with no nylon, rawhide or animal byproducts. Learn what a plant-based dog chew is and what cellulose is.
• Independently tested. In February 2026, TÜV SÜD found no detectable PFAS, phthalates or BPA in our material.
• Lower-impact material. An independent life cycle assessment by nova-Institut found our material generates 67–79% less CO₂ than virgin plastic (ABS). Unlike nylon, it biodegrades in industrial composting conditions. Read the 2025 Environmental Report.
• Dental enrichment textures. Ridges and nubs help buff away plaque and massage gums.
• Vegetarian scents. Veggie, Beef and Venison are hypoallergenic scent infusions made without animal byproducts.

Find your dog's nylon bone alternative

Switching from nylon? If your dog is a power chewer, start with Hard in the size above their weight range if they're near the top of it. Otherwise, Moderate is a good place to start. The Chews-ing Guide will match your dog in four quick questions, and if you pick the wrong durability, our Free Replacement Guarantee swaps it for free. Big dog? Here's how big a bone your big dog needs.

Chewing BetterBone safely

BetterBone is a chew toy, not a treat, and isn't meant to be eaten. Small flakes are normal and generally safe if accidentally swallowed. Large pieces are not, so take the bone away and move up a density. Supervise chew time and replace the bone when the ends are about 50% worn or it's small enough to swallow. Our dog chew safety guidelines show exactly when.

Frequently asked questions

Are nylon dog chews safe?

Nylon dog chews aren't edible and can be hard enough to crack teeth, so they need close supervision and regular replacement. Choose the right size and hardness for your dog, and stop use if you see sharp edges or broken pieces.

Can nylon bones break dogs' teeth?

Yes, very hard chews can fracture teeth, especially in powerful chewers. Use the AAHA thumbnail test: if you can't make a small dent, the chew may be too hard.

What happens if my dog swallows part of a nylon bone?

Nylon isn't digestible, so swallowed pieces can cause choking or a blockage. Contact your veterinarian right away.

Are nylon bones good for puppies?

Very hard nylon chews are usually too tough for developing puppy teeth. A softer chew, like BetterBone Light, is a better fit for teething puppies.

What is a good alternative to nylon dog chews?

Look for a durable chew that wears into small flakes instead of sharp edges and isn't made from petroleum-based plastic. BetterBone Hard is our plant-based alternative for power chewers who usually reach for nylon.
