Quick answer: For aggressive and power chewers in Australia, the best chew is a long-lasting air-dried collagen chew. Fangz collagen chews are air-dried for up to four weeks, which creates a density that lasts hours per session at minimum, and a single chew often lasts days to weeks depending on how hard your dog goes at it. The chew softens with saliva so it won't fracture your dog's teeth. Yak chews, antlers, and hard nylons last, but they do it by being harder than a tooth, and that's exactly how they break one.
There's a rule in vet dentistry that most dog owners find out the hard way: if a chew is harder than your dog's tooth, it can break the tooth.
Power chewers go through softer chews in minutes, so owners reach for the hardest thing they can find. Yak chews, antlers, deer hooves, Nylabones. The logic makes sense. The result doesn't. Harder-than-tooth products last longer because they're indestructible, not because they're safe. Indestructible and tooth-safe are not the same thing, and for a dog who chews hard, that difference is expensive.
This guide cuts through every option on the Australian market. We'll tell you what lasts, what's safe, and what's both.
Does "harder" always mean "longer-lasting"?
No. This is the central mistake most owners make.
A chew lasts longer for one of two reasons: it's so hard the dog can't break it, or it's dense enough to resist destruction while still being softer than a tooth. The first category (antlers, yak chews, hard nylons) works until the dog's jaw torque exceeds what the product can handle, at which point something fractures. Usually a piece of the chew. Sometimes a carnassial tooth.
The second category (air-dried collagen) works because air-drying removes moisture slowly, over weeks, which creates a dense protein matrix throughout the chew. A dog can grind it down, but the surface resistance means each session lasts hours, not minutes. And because the chew softens with saliva as it's worked, it never becomes a ballistic fragment. A single Fangz chew lasts hours per session at minimum, and across multiple sessions a chew typically endures days to weeks depending on how intensely your dog chews.
Density from air-drying is the mechanism. That's why Fangz chews last.
The "harder than a tooth" rule: what vets actually see
Veterinary dentists describe the thumbnail test: if you press a chew hard against your thumbnail and it doesn't indent, it's too hard for your dog's teeth. Enamel hardness sits around 5 on the Mohs scale. Antlers may look softer on a hardness chart, but they're pressure-cured to a surface density that doesn't yield under impact load, and they don't soften with saliva. The structural behaviour under bite force matters more than the static hardness number.
Slab fractures of the upper fourth premolar (carnassial tooth) are among the most common tooth fractures vets see in dogs, and hard chews are one of the leading causes. A fractured carnassial often needs extraction or a root canal, both typically running $2,000 to $3,500 at a specialist, more in major cities.
The American Veterinary Dental College (AVDC) recommends against any chew you cannot make an impression in with your thumbnail. Antlers, hooves, yak chews, and hard nylons typically fail this test.
See our full breakdown of tooth fracture risk and why yak chews are a particular concern.
How air-dried density actually works (the reason Fangz lasts)
Standard dehydration runs at 60 to 75°C, pulling moisture out in a matter of hours. The result is a firm but brittle product that snaps under load.
Air-drying runs cooler, over a much longer period. Fangz chews are slowly air-dried for up to four weeks. At that timeframe, the collagen matrix contracts gradually, which preserves the protein structure and creates a high-density, flexible-under-load chew. It doesn't snap. A power chewer grinds the surface down over time, but the internal structure resists that grinding for hours.
The collagen base (beef collagen plus beef gelatine) reinforces this. Collagen is a structural protein that holds its form under sustained mechanical stress. It's also the same structural protein in your dog's joints, tendons, skin, and nails. So the chew is doing two things: occupying a power chewer for hours, and delivering collagen that supports joint mobility, skin, coat, and gut health as they work through it.
Three ingredients per chew. No fillers, no additives, no preservatives. That's the whole product.

Duration note: all duration estimates for power chewers are relative and vary by dog size, breed, and jaw strength. "Hours" for Fangz assumes appropriate size selection (see size guide below).
What actually lasts for power chewers: ranked
1. Fangz air-dried collagen chews (our pick)
Lasts hours per session for most power chewers, and a single chew typically endures days to weeks across multiple sessions. Softens with saliva so it never becomes a hard fragment. Made from beef collagen, beef gelatine, and one superfood per flavour: Pumpkin (tummy-friendly), Beetroot (iron, folate), Spirulina (greens, protein), or Goat's Milk (mild, creamy). About 93% protein, about 1% fat. No sugar, no preservatives, no artificial crap.
Handmade by Helen and John in Brisbane. Human-grade facility. 100% Australian ingredients. Puppy-safe from 4 months. Odourless.
Right for: power chewers that need hours of occupation, owners who want a tooth-safe option, dogs with food sensitivities (Pumpkin and Goat's Milk are both gentle), dogs where you want the chew doing more than just occupying them.
Where it falls behind: not the cheapest chew on a per-unit basis. If your dog is a gulp-swallower rather than a genuine chewer, this isn't for them (and neither is any chew; supervise).
Size selection matters: Small (under 8kg), Medium (8 to 15kg), Large (over 15kg). A Staffy or Kelpie needs a Large. Getting this wrong is the most common reason a Fangz chew doesn't last as long as expected. Build a Fangz pack with the right size for your dog.
2. Yak / Himalayan chews
Last a long time. Genuinely. But they earn that duration by being pressure-cured to rock-hard density, and they do not soften with saliva. Under the bite force of a Staffy or German Shepherd, they can and do fracture. When a piece breaks off at the wrong angle, it can fracture a tooth at the same time.
Right for: moderate chewers where owners accept the tooth-fracture risk and supervise closely.
Falls behind on: tooth safety, especially for aggressive chewers with strong jaw torque. Vets report yak chew tooth fractures with notable frequency. Read the full yak chew safety breakdown.
3. Bully sticks
Digestible, palatable, widely available. For most dogs they last 20 to 60 minutes, which is acceptable but not "hours." For a genuine power chewer (Staffy, Kelpie, Labrador), you're looking at closer to 15 minutes. The other notable issue: the smell. Bully sticks are made from bull pizzle (the unprocessed version) and most variants have a strong odour. Odour-free versions exist but use an additional processing step.
Right for: moderate chewers, rewards, variety in the rotation. Not the answer if you need the dog occupied while you work.
Falls behind on: duration for power chewers, smell.
4. Deer antlers
The longest-lasting natural chew on the market by sheer hardness. They can last weeks to months for most dogs. The problem is the same as yak chews, and arguably worse: antler is bone material, it doesn't soften, and at the bite pressures a power-chewer generates, it can fracture a tooth with a single hard bite. Split antlers (the inside is exposed) are softer than whole antlers, but still sit in the hard-chew category.
Veterinary dental specialists group antlers alongside rocks and ice as chews to avoid for dogs prone to dental fractures. See our full antler safety guide.
Right for: light to moderate chewers where supervision is constant and the owner accepts the risk profile.
Falls behind on: tooth safety, digestibility (low), fragment risk.
5. Nylabones (nylon chews)
Nylabones are marketed as indestructible and safe for power chewers. The indestructible part is accurate. The safe part has caveats. Dogs chewing Nylabones shave off nylon micro-fragments with each session. Those fragments are not digestible. Nylabone's own packaging recommends replacing the chew if large pieces begin to break off, but by then some of those fragments have been swallowed.
The material hardness is also in the range where tooth fractures can occur with heavy bite pressure.
Right for: dogs that need a mechanical chewing outlet and where the owner wants zero consumption (training tool, not a treat).
Falls behind on: digestibility, fragment risk, tooth-fracture risk under heavy load.
6. Coffee wood chews
A newer category in Australia. Made from pressed coffee wood offcuts. Harder than bully sticks but softer than antler. They don't splinter the way some woods do (the grain structure is different). Duration for moderate chewers is several sessions. Not digestible (the dog scrapes fibres off the surface). A reasonable middle-ground option for dogs that need texture variety.
Right for: variety in the chew rotation, moderate-to-heavy chewers who need something that lasts but won't swallow it.
Falls behind on: no nutritional value, not digestible, limited Australian availability.
7. Rawhide
We list rawhide last because, for most power chewers, it belongs off the list entirely. The main issue isn't duration (power chewers can soften and swallow large rawhide chunks quickly). It's the combination of choking risk from large softened pieces, potential chemical treatment in processing (lye, bleach, and hydrogen peroxide are used in standard production), and low digestibility. For power chewers especially, rawhide tends to be swallowed in large chunks before it's broken down enough to be safe. Full rawhide safety guide here.
Right for: not our recommendation for power chewers.
Sizing guide for power chewers
For aggressive chewers, always size up relative to what you'd expect for the weight category. A 14kg Staffy-cross with strong jaw musculature should get a Large, not a Medium. The chew needs to resist their bite, not be overpowered by it.
| Size | Weight guide | Power-chewer note |
|---|---|---|
| Small | Under 8kg | Toy breeds, puppies (4+ months) |
| Medium | 8 to 15kg | Moderate chewers in this weight range |
| Large | Over 15kg | Standard for most power chewers; size up if in doubt |
If the chew vanishes in under 30 minutes, you've sized down. Go up. See the Fangz Build Your Pack page to pick your size and flavour.
Breed-specific notes
Staffies and Bull breeds: high jaw pressure, dense muscle, persistent chewers. Need a Large regardless of weight. Air-dried density is the right match. Antler and yak carry elevated fracture risk with this jaw type.
Labradors and Golden Retrievers: tend to be enthusiastic rather than targeted. They'll work a Fangz for hours. Main risk is gulp-swallowing, so supervise the first session and confirm they're chewing rather than swallowing whole.
German Shepherds: methodical chewers. Strong jaw, persistent. Large Fangz works well. Be careful with yak and antler at this jaw pressure.
Border Collies: chew with intensity when under-stimulated. The combination of a Fangz and a long-lasting mental outlet is the right stack. See our guide on chews for working breeds.
Small power chewers (Jack Russells, Dachshunds): pound-for-pound some of the most persistent chewers. A Small Fangz is right for the weight but watch the duration. A Jack Russell can give a Small a serious workout.
For more on breed-specific picks, see our guides on chews for large breeds and chews for aggressive chewer types.
The 10% rule for power chewers
Treats and chews should make up no more than 10% of your dog's daily calorie intake. For power chewers who go through chews fast, this is easy to blow out without realising. Fangz chews are about 93% protein and about 1% fat, which means the caloric density is relatively low and the 10% ceiling is easier to stay inside. High-fat chews (bully sticks, pig ears) burn through the 10% allowance faster.
If your dog is a large breed on a daily chew routine, track the calorie contribution. It's less of an issue with a lean collagen chew than with a high-fat alternative.
Our pick
For Australian power chewers, Fangz collagen chews are the right answer. Not because they're the absolute longest-lasting chew on the market on raw duration (antlers last longer, but at a cost your vet will invoice you for). Because they sit at the intersection of "lasts hours per session, and days to weeks across sessions," "safe for a dog that really chews," and "you know every ingredient in it."
Three ingredients. Handmade in Brisbane. Air-dried for up to four weeks. Softens with saliva so it won't fracture a tooth.
Try a Fangz chew for your power chewer and see how long it lasts.
