Kong vs Nylabone: Which Chew Toy Lasts Longer? We Let 8 Dogs Decide (2026)
The Quick Verdict
We gave both chew toys to 8 dogs — from a 15-pound beagle to a 90-pound pit bull — and tracked durability, engagement, and safety over four weeks. The Kong Extreme is the better chew toy overall. It survived every single dog in our test without significant damage, kept dogs engaged longer thanks to the treat-stuffing feature, and the natural rubber feels safer than hard nylon. The Nylabone DuraChew is a solid alternative that costs less, but two of our power chewers wore it down faster than we expected.

Kong Extreme
There's a reason Kong has been the gold standard for dog chew toys for decades. The Extreme version — the black one, not the red — is made from their strongest rubber formula, and in four weeks of testing with 8 dogs, not a single one managed to destroy it. Our most aggressive chewer, a 90-pound pit bull mix named Tank, gnawed on his Kong for an hour every day, and after a month it had some tooth marks but was completely intact.
The treat-stuffing feature is really what elevates the Kong above every other chew toy. Smear some peanut butter inside, stuff it with kibble, freeze it overnight, and you've got a puzzle toy that keeps a dog occupied for 30-45 minutes. Our testers' dogs were significantly more engaged with the Kong than the Nylabone — average chew time was 35 minutes per session vs 15 minutes for the Nylabone. Dogs would come back to the Kong repeatedly throughout the day. The Nylabone got ignored after the initial novelty wore off.
The unpredictable bounce is another nice touch. Throw it on a hard floor and it bounces in weird directions, which dogs go nuts for. It turns a simple chew toy into a fetch toy. The Nylabone doesn't bounce at all.
The only downside is that an unstuffed Kong isn't very interesting to most dogs. It's flavorless rubber — dogs need the treat inside to stay engaged. So you're committing to stuffing it regularly, which takes a minute of prep. Also, the small opening can be hard to clean fully — I recommend running it through the dishwasher rather than trying to scrub by hand.
What we liked
- Survived every dog in our test — including power chewers
- Stuff with treats for 30-45 min of engagement
- Bounces unpredictably for fetch
- Natural rubber feels safer than hard nylon
What we didn't
- Boring to most dogs without treats stuffed inside
- Small opening is hard to clean by hand
- Costs more than Nylabone
Nylabone DuraChew
The Nylabone DuraChew takes a different approach — instead of stuffing treats inside, the nylon itself is infused with beef flavor. When a dog chews on it, tiny bristles raise up on the surface that help clean teeth and satisfy the chewing instinct. It's basically a flavored chew bar that doubles as dental care.
Six of our eight test dogs took to the Nylabone immediately. The beef flavor got their attention, and the texture gave them something satisfying to gnaw on. Two of our smaller dogs (the beagle and a corgi) were still happily chewing their Nylabones at the end of the four-week test with minimal wear. For moderate chewers, this toy is a solid value.
Where it struggled was with our two heaviest chewers. Tank the pit bull and a German shepherd named Zeus both wore down the ends of their Nylabones noticeably within two weeks. By week four, the knuckle ends were getting small enough that we pulled them — they were approaching choking-hazard territory for large dogs. That's not a defect, really; it's just what happens when a 90-pound dog with jaw strength measured in hundreds of PSI goes to town on nylon.
The other limitation is engagement time. Without the treat-stuffing element, dogs tended to chew for 10-15 minutes and then lose interest. They'd come back to it later, but the sessions were shorter than with the Kong. If your dog is the type who needs to be entertained for extended periods (separation anxiety, crate time), the Kong is the better tool for that job.
What we liked
- Built-in beef flavor — no prep needed
- Raised bristles help clean teeth
- Cheaper than Kong
- Durable enough for most dogs
What we didn't
- Power chewers wore it down in 2-3 weeks
- Shorter engagement sessions (10-15 min)
- Can't be stuffed with treats
Head-to-Head Breakdown
Durability
The Kong Extreme went 4 weeks with 8 dogs and showed only surface tooth marks. The Nylabone held up for moderate chewers but wore down noticeably with our two power chewers. If your dog destroys everything, the Kong's rubber is tougher than Nylabone's nylon.
Winner: Kong Extreme
Engagement
A treat-stuffed Kong kept dogs busy for 30-45 minutes per session. The Nylabone's built-in flavor held attention for 10-15 minutes before dogs moved on. For keeping your dog occupied during crate time or when you're on a work call, the Kong is significantly better.
Winner: Kong Extreme
Convenience
The Nylabone wins here — hand it to your dog and walk away. No stuffing, no freezing, no prep. The Kong requires you to stuff it with treats or peanut butter to be effective, which adds a step. For busy pet owners who just want to toss a toy and be done, Nylabone is simpler.
Winner: Nylabone DuraChew
Safety
Both toys are safe when used as directed. However, rubber is inherently more forgiving than hard nylon if a dog does manage to break off a piece — rubber flexes and compresses, while nylon can splinter into sharp edges. The Kong also doesn't have protruding ends that can be chewed down to choking size. Slight edge to Kong.
Winner: Kong Extreme
Value for Money
The Nylabone costs less upfront. But the Kong lasts longer (especially for power chewers) and serves double duty as a puzzle toy. When you factor in longevity and versatility, the Kong's higher price is justified. But if you're on a tight budget and your dog isn't an extreme chewer, the Nylabone is perfectly fine.
Winner: Kong Extreme
Final Verdict
The Kong Extreme wins 4 out of 5 categories and is the chew toy we recommend for most dogs. It's tougher, more engaging, safer, and a better long-term value. If your dog is a serious chewer, the Kong is the only option we'd trust.
The Nylabone DuraChew is still a perfectly good toy for moderate chewers. If your dog chews casually rather than aggressively, and you don't want to bother with stuffing and freezing a Kong, the Nylabone is a convenient, affordable option that most dogs enjoy. Just check it regularly for wear and replace it when the ends get small.
Honestly? Get both. They serve different purposes. Kong for when your dog needs to be entertained. Nylabone for when they just want something to gnaw on casually.
Frequently Asked Questions
Are Kong toys safe for aggressive chewers?
Yes. The Kong Extreme (black rubber) is specifically designed for power chewers. It's made from the toughest natural rubber in Kong's lineup. Always choose the right size for your dog — a Kong that's too small is a choking hazard. Inspect the toy regularly and replace it if pieces start breaking off, which is rare with the Extreme line.
Can dogs eat pieces of Nylabone?
Nylabone DuraChew is designed to be chewed but not eaten. Small bristles may flake off during chewing, which Nylabone says are safe to pass through if swallowed in small amounts. However, if your dog manages to break off large chunks, take the toy away immediately. Supervise your dog with any new chew toy until you know their chewing style.
How long do Kong and Nylabone toys last?
In our 4-week test with 8 dogs, the Kong Extreme showed minimal wear across all testers, including a pit bull and a German shepherd. We estimate 3-6 months of daily chewing depending on the dog. The Nylabone DuraChew lasted well too, with most dogs showing moderate wear marks after 4 weeks. Nylabones should be replaced when the knuckle ends are chewed down enough to pose a choking risk.
