Quick answer: If your dog destroys every chew you hand them, they need a dense, slowly air-dried collagen chew, not a harder plastic toy or a pressed rawhide. Fangz collagen chews are air-dried for about 2 to 4 weeks, giving them the kind of density power chewers can't blast through in minutes. A Fangz chew lasts hours at minimum, and a single chew often lasts days to weeks depending on how hard your dog goes at it. Most "tough" chews fail because the manufacturing process, not the material, is wrong.
You've bought the thick bully stick. The antler. The "extreme chewer" rawhide roll from the pet shop. And you've watched your dog turn all of it into a wet stub in under ten minutes.
It's not your dog. It's the chews.
Most long-lasting dog chews aren't actually built for dogs that chew hard. They're built to look durable on a shelf. The ones that genuinely last are made differently, from the inside out. Here's what the research actually shows, and what we've learned making chews for dogs that would eat through a kitchen chair.
Why Does My Dog Destroy Every Chew So Fast?
Power chewers destroy chews quickly because most chews don't have the internal density to resist sustained, hard chewing.
The chewing force of a large dog ranges from around 150 to 300+ psi depending on breed and bite style. Most commercial chews, including pressed rawhide, most bully sticks, and even some "tough" dental chews, are manufactured using processes that leave air pockets, soft centres, or laminated layers that a strong jaw finds and exploits quickly.
The culprit is almost always how the chew was made, not what it was made from.
Three failure modes appear consistently:
Pressed rawhide: Made from multiple layers of hide pressed together. Power chewers strip those layers apart fast. What looks like a thick roll comes apart in sheets. The outer layer goes in minutes.
Soft-baked or extruded dental sticks: Products like Dentastix are primarily cereal and starch-based, soft enough to be manufactured in a star shape on industrial equipment. They crumble, they dissolve, they're gone. The printed ingredient list on Dentastix (as printed on the pack sold in Australia) lists cereal first, followed by humectant and starch. That tells you what you're actually giving your dog.
Standard bully sticks: A single protein tube, which sounds good, but most bully sticks are dried quickly (hours, not weeks) to hit commercial production timelines. Quick-dried bully sticks have a more open, fibrous texture. A strong chewer can compress that texture and tear through it. Duration: typically 5 to 30 minutes for a power chewer, depending on size.
What Actually Lasts: The Duration Hierarchy
Not all chews are created equal. Here's an honest ranking based on what the structure of each chew actually delivers to a strong chewer.
| Chew type | Typical duration (power chewer) | Tooth-safe? | What gives out first |
|---|---|---|---|
| Dental sticks (Dentastix-style) | 2 to 5 minutes | Yes (soft) | Dissolves on contact |
| Pressed rawhide | 5 to 15 minutes | Risky (choking) | Layers peel apart |
| Standard bully stick | 10 to 30 minutes | Yes | Fibrous structure compresses |
| Collagen chew (fast-dried) | 30 to 60 minutes | Yes | Centre softens first |
| Yak chew (Himalayan-style) | 1 to 3 hours | No (fractures teeth) | Outer surface worn down |
| Deer antler | 2 to 6 hours | No (fractures teeth) | Outer surface worn down |
| Collagen chew (slow air-dried, 2 to 4 weeks) | Hours per session; one chew lasts days to weeks | Yes (softens with saliva) | Gradually erodes evenly |
The top performers in duration are yak chews, antlers, and slowly air-dried collagen chews. Two of those three will crack your dog's teeth. One won't.
Why Yak Chews and Antlers Last but Cause Tooth Fractures
Yak chews and antlers survive power chewers because they are genuinely hard. That's also the problem.
Yak chews are compressed and pressure-cured from dried yak milk. Antlers are, obviously, antler bone. Neither material softens with saliva. They stay rock-hard through the entire chewing session.
Vets call tooth fractures on hard chews "slab fractures." The cusps of the upper back teeth (carnassial teeth) absorb repeated impact against an unyielding surface until a section cracks away. The fracture often goes below the gum line. Treatment requires extraction or root canal under general anaesthetic.
The rule most veterinary dentists use: if you can't make a dent in it with your thumbnail, it's too hard for your dog to chew safely.
Neither antlers nor yak chews pass that test.
For more on why the "toughest" chews carry the highest dental risk, read our guide: Are yak chews safe for dogs? (what vets actually see).
The Air-Drying Mechanism: Why It Creates Real Duration Without the Fracture Risk
Fangz chews are slowly air-dried for about 2 to 4 weeks in our Brisbane facility. That process is the reason for the duration, and it's worth explaining properly. If you want to try one, build your Fangz pack and pick the size that suits your dog.
Beef collagen is a dense protein matrix. When you dry it slowly over weeks (rather than quickly over hours), the water leaves the structure gradually and uniformly. The result is a chew with extremely tight, dense internal structure, minimal air pockets, no soft centre, and no layered construction that peels.
That density is what a power chewer hits when they start working on a Fangz chew. They can compress it, but they can't tear through it the way they tear through a bully stick or strip apart a rawhide layer. It gives ground slowly and evenly.
The second mechanism is saliva softening. Beef collagen softens with saliva from the outside in. As your dog chews, the outer surface becomes slightly pliable. They get purchase and flavour, but the inner material stays dense. The chew erodes like a bar of hard soap rather than fragmenting like a biscuit.
This is the opposite of what happens with yak chews and antlers. Those don't soften. They stay hard all the way through. The saliva-softening mechanism is what makes Fangz tooth-safe. It's also what gives us the "hours, not minutes" duration without the fracture risk.
The 10% Rule and Power Chewers
One guardrail worth knowing: treats and chews, including long-lasting ones, should make up no more than 10% of your dog's daily calorie intake. This is the standard vet guidance on treat portion sizes. (For more detail: How many chews a day is safe for a dog? (the 10% rule).)
For a heavy chewer who gets a long-lasting chew daily, this matters. Fangz is about 93% protein and around 1% fat. That makes the calorie load relatively low per chew compared to bully sticks (which run much higher in fat) or treat-stuffed Kong scenarios. You can give a Fangz chew without blowing your dog's daily calorie budget.
The Science Behind Why Chewing Settles a Dog Down
A 2023 PMC study specifically looked at how dogs respond emotionally to long-lasting chews during short periods of social isolation. The finding: dogs given long-lasting chews showed the most positive and calm emotional states compared to dogs given treat-dispensing toys or smart devices.
That's not just "they were distracted." The repetitive chewing action releases calming endorphins. It's a self-soothing mechanism. A chew that lasts long enough for that mechanism to kick in is categorically different from one that's gone in five minutes.
For power chewers specifically, this matters beyond the furniture. A dog that chews hard is often a dog with a high need for mental engagement. Five minutes of chewing doesn't give that dog what they need. Hours of chewing does.
What to Give a Power Chewer: A Straight Decision Guide
Here's how to choose, depending on your dog's situation.
If your dog destroys every chew in under 10 minutes: You need a slow air-dried collagen chew, minimum. Standard bully sticks, rawhide, and dental sticks won't make the cut.
If you've tried yak chews or antlers and they last, but you're worried about teeth: Switch to air-dried collagen. Same duration range in most cases, without the fracture risk. Read our full comparison: Yak chew vs collagen chew: which lasts longer and is safer?.
If your dog has already cracked a tooth on a hard chew: Collagen chews are the recommended safe alternative. The softening mechanism is specifically what vets point to when recommending away from hard chews.
If you have a large dog over 15kg: Go the Large Fangz (about 150g). For dogs under 8kg, the Small (about 50g). Sizing matters because a chew that's too small for a big dog stops being a challenge quickly. See all sizes on the Fangz Build Your Pack page.
If you have a puppy: Fangz is safe from 4 months old. Puppies often need something to work on while teething. A collagen chew that softens with saliva is a safer option than anything rock-hard. For more on teething options: What to give a teething puppy to chew (safe options).
Where Fangz isn't the answer: If you're purely looking for the cheapest chew per session, there are cheaper options. If your dog is a gulp-swallower who doesn't actually chew (some dogs bolt treats whole), a long-lasting chew needs supervision regardless. That's the honest list.
Fangz: The 3-Ingredient Build
Every Fangz chew has 3 ingredients: beef collagen, beef gelatine, and one superfood powder per flavour.
Four flavours:
- Pumpkin: real pumpkin powder, tummy-friendly, gentle
- Beetroot: dried beetroot powder, iron and folate
- Beef and Spirulina: spirulina powder, greens and protein
- Goat's Milk: goat milk powder, mild and creamy, good for sensitive dogs
No preservatives. No additives. No fillers. Odourless (so no stink on the couch). About 93% protein, around 1% fat across three flavours. Goat's Milk sits at about 82% protein and 2% fat. Shelf life of approximately 2 years sealed.
Made by Helen and John in Brisbane, in a human-grade facility, with 100% Australian ingredients. Ships Australia-wide. If your dog doesn't love it, we'll refund you. Try a Fangz chew and pick your flavour and size.

The Bottom Line
If your dog destroys every chew in minutes, you're buying the wrong type of chew, not the wrong brand of the same type.
The structure of the chew determines the duration. Slow air-dried collagen has the density that power chewers actually meet resistance with. It softens gradually with saliva, which is what makes it last and what makes it safe for teeth.
The two categories that outlast it (yak chews, antlers) do so by being genuinely hard. Hard enough to fracture teeth. That's not a trade-off worth making.
