When it comes to dog chew toys, two brands dominate the market: Kong and Nylabone. Both have been around for decades, both claim to be tough enough for aggressive chewers, and both have loyal followings among dog owners and vets.
But they’re actually quite different products with different strengths. Choosing between them depends on your dog’s chewing style, size, and what you want from a toy. Let’s break down the comparison.
The Quick Answer
If you want a stuffable, multi-purpose toy that doubles as a food puzzle: Kong. If you want a dedicated chew toy focused purely on satisfying the urge to gnaw: Nylabone. Most dog owners end up owning both, and that’s probably the right call.
Kong: The Overview
Kong Classic
The original Kong has been around since 1976, and the design hasn’t changed much because it works. The distinctive snowman shape is made from natural rubber that bounces unpredictably (great for fetch) and has a hollow center you can stuff with treats, peanut butter, or kibble.
What Kong is best at: Mental stimulation. A frozen, stuffed Kong can keep a dog occupied for 30-60 minutes, making it invaluable for crate training, separation anxiety, and keeping dogs busy. It’s a toy, a food puzzle, and a behavioral tool all in one.
Kong rubber is tough, but it’s not indestructible. The Classic (red) is designed for average chewers. The Kong Extreme (black) uses a tougher rubber compound for power chewers. Even the Extreme version can be destroyed by the most determined chewers, though.
Durability rating: 7/10 (Classic) to 8.5/10 (Extreme)
Nylabone: The Overview
Nylabone DuraChew
Nylabone takes a fundamentally different approach. Their chew toys are made from tough nylon or rubber compounds and are designed specifically for the act of chewing — they don’t bounce, they can’t be stuffed, and that’s by design. The textured surface satisfies the chewing instinct and helps clean teeth as your dog gnaws.
What Nylabone is best at: Pure chewing durability. Nylabones are generally harder and more resistant to being destroyed than Kongs, especially for dogs who are dedicated power chewers. They come in flavored varieties (chicken, bacon, peanut butter) that maintain their scent throughout the life of the toy.
The product line is broader and can be confusing. The key distinction is DuraChew (for powerful chewers — hard nylon), FlexiChew (for moderate chewers — softer material), and Puppy Chew (for teething puppies — gentle on developing teeth).
Durability rating: 8/10 (FlexiChew) to 9/10 (DuraChew)

Detailed Comparison by Category
Durability
Winner: Nylabone
For pure chew resistance, Nylabone’s DuraChew line edges out Kong. The hard nylon compound is simply tougher than rubber. Dogs that destroy a Kong Classic in days might take weeks or months to wear down a DuraChew.
That said, Kong’s Extreme line (the black one) is significantly tougher than the Classic and comes close to Nylabone for most dogs. And neither product is truly “indestructible” — every manufacturer will tell you that no toy is safe for unsupervised use with aggressive chewers.
Important safety note: With Nylabones, watch for small pieces that break off. While the product is designed to produce tiny shavings (which pass through safely), larger chunks should be taken away. Replace any Nylabone that’s been chewed down to a size your dog could swallow.
Mental Stimulation
Winner: Kong (by a mile)
This is Kong’s superpower. A stuffed Kong engages your dog’s brain, not just their jaws. Here are some stuffing ideas that work well: smear peanut butter (xylitol-free) inside and freeze it, layer kibble with banana and freeze, stuff with plain Greek yogurt and blueberries, or pack wet dog food inside and freeze for an extra-long challenge.
A frozen stuffed Kong can keep most dogs busy for 30-60 minutes. For puppies or dogs with separation anxiety, this is invaluable. Nylabones offer no equivalent mental engagement.
Dental Health
Winner: Nylabone (slight edge)
Both toys help clean teeth through the chewing action, but Nylabone’s textured ridges and nubs are specifically designed for dental benefits. The DuraChew line includes raised bristle designs that help reduce plaque and tartar buildup as your dog chews.
Kong’s smooth rubber surface cleans teeth too, but it’s not the primary design purpose. Neither product replaces actual tooth brushing, but both are better than no chewing at all.
Value for Money
Winner: Tie
Both products are reasonably priced ($8-18 depending on size), and both last significantly longer than most dog toys. The value proposition is different though: with Kong, you’re paying for the toy plus the ongoing cost of stuffing ingredients (peanut butter, treats, etc.). With Nylabone, it’s a one-time purchase that works until it’s chewed down.
For dogs that go through toys quickly, Nylabone typically lasts longer per dollar. For dogs where mental stimulation is the priority, Kong delivers more value through its versatility.
Safety
Winner: Tie (with caveats)
Both brands have strong safety records, but both require appropriate sizing and supervision.
With Kong, the main risk is choosing too small a size — dogs can get their jaw stuck in a Kong that’s too small. Always size up if you’re between sizes. The rubber is non-toxic and designed to be safe if small pieces are ingested.
With Nylabone, monitor for large chunks breaking off. The small shavings that come off during normal chewing are designed to pass through the digestive system safely, but larger pieces can pose a choking hazard. DuraChew products should be replaced when they’re chewed small enough to fit entirely in your dog’s mouth.
Which Should You Choose?
Get a Kong if your dog:
- Is food-motivated and loves treats
- Needs mental stimulation (bored easily)
- Has separation anxiety or crate-training needs
- Is a puppy (the Classic and Puppy Kong are great teething toys)
- Enjoys fetch (it bounces unpredictably — dogs love this)
Get a Nylabone if your dog:
- Is a dedicated, aggressive chewer who destroys most toys
- Needs something to gnaw on for extended periods
- Could benefit from dental cleaning during chew time
- Isn’t particularly food-motivated
- Goes through Kong Extremes too quickly
Get both if your dog:
- Is a well-rounded chewer who enjoys variety (most dogs)
- Could benefit from mental stimulation AND dedicated chewing
- Is a puppy who needs different textures for teething
Frequently Asked Questions
Can dogs swallow pieces of Kong or Nylabone?
Small rubber shavings from Kong or tiny nylon shavings from Nylabone are designed to pass through safely. However, larger pieces can be a choking or intestinal blockage risk. Always supervise chewing sessions and replace toys that are breaking apart or have been chewed small enough to swallow whole.
Which is better for puppies?
Kong Puppy (the light blue/pink ones) are specifically designed for teething puppies — the rubber is softer and gentler on developing teeth and gums. Nylabone also makes a Puppy Chew line with softer material. For puppies, we slightly prefer Kong because the stuffing capability makes crate training much easier.
How do I clean a Kong?
The easiest method is to fill it with warm soapy water, use a bottle brush to scrub inside, and rinse thoroughly. You can also put Kong toys on the top rack of your dishwasher. Clean weekly if you’re stuffing it regularly.
My dog destroys everything. Will either of these last?
Try the Kong Extreme (black) first — it’s the toughest rubber option. If that doesn’t last, move to Nylabone DuraChew in the appropriate size. For truly extreme chewers, also look at Benebones (another tough nylon option) or consider that some dogs simply shouldn’t have chew toys unsupervised.
The Bottom Line
Kong and Nylabone are both excellent products that serve different purposes. Kong is the more versatile choice — it’s a toy, a food puzzle, and a training tool. Nylabone is the more durable choice for dogs whose primary need is something tough to chew on.
Our recommendation for most dog owners: start with a Kong Classic (or Extreme for strong chewers) because the stuffing capability adds so much value beyond just chewing. Then add a Nylabone DuraChew as a secondary option for times when your dog just wants to gnaw.
And remember — no toy is a substitute for supervision. Check all chew toys regularly for wear and replace them before they become a safety hazard.
