Quick answer: Collagen chews last longer and are safer. Yak chews are pressed and hard-dried to a density that doesn't soften with chewing, which is why vets regularly see fractured teeth from them. Collagen chews (like Fangz) are slowly air-dried to create lasting density AND soften with saliva, so your dog can chew for hours without cracking a tooth. If your dog is a power chewer and you'd prefer not to spend thousands at the emergency vet, the choice is clear.
Most owners who buy yak chews are doing the right thing. They're looking for something that lasts, something natural, something their dog will actually work at. The problem isn't the intention. It's that yak chews have a structural flaw that doesn't show up until it's too late: they're so hard they fracture teeth under sustained chewing pressure.
Collagen chews solve the same job (long-lasting, high-value, natural) without the fracture risk. Here's the full breakdown so you can see exactly why.
What is a yak chew and how is it made?
Yak chews (also sold as Himalayan chews or yak milk chews) are made from dried yak and cow milk. The milk is boiled, mixed with lime juice or salt to separate the solids, pressed into blocks, and then hard-dried or smoked until the moisture is almost entirely removed. The process creates an extremely dense, hard block.
The drying and pressing creates a product that doesn't soften meaningfully under a dog's saliva or chewing. What goes in hard stays hard. That's the mechanism behind both its durability AND its dental risk: a substance that cannot soften will eventually exert enough crack-inducing force on a tooth if the dog chews at the wrong angle or works at it long enough.
What is a collagen chew and how is it made?
A collagen chew is made from beef collagen (the connective tissue surrounding the hide), typically set with a small amount of beef gelatine, and then slowly air-dried over weeks. Fangz collagen chews, for example, are air-dried for about two to four weeks in a human-grade facility in Brisbane.
The slow air-drying process is the mechanism that makes them last. It removes moisture gradually, which creates a dense, fibrous structure that power chewers have to genuinely work at. But because the base material is collagen (a biological protein your dog's body recognises and responds to), it softens with sustained saliva contact. The density keeps them busy for hours. The softening keeps teeth safe.
Can a yak chew break a dog's tooth?
Yes. This is not a fringe concern.
Slab fractures (where a large piece of the tooth shears off) are among the most common dental injuries vets see in dogs who chew hard objects. The general veterinary guideline is the "thumbnail rule": if you press the chew against your thumbnail with the force a dog would apply and it doesn't give at all, it's too hard. Yak chews don't give. Neither do antlers, beef marrow bones, and Nylabones.
The consequence of a slab fracture is often either a root canal (typically $1,500 to $3,000 or more with a veterinary dentist) or extraction (commonly $500 to $1,500 at a general practitioner, higher at a specialist). The tooth cannot be left with the pulp exposed.

Which lasts longer: yak chew or collagen chew?
This is where the comparison gets interesting, because yak chews have a reputation for lasting a long time. And they do last, for many dogs. But so do quality collagen chews, and the comparison isn't as one-sided as the yak camp would have you believe.
The honest answer is: it depends on the dog's size, chewing style, and the specific product. A large Staffy on a small yak chew will destroy it faster than a Cavoodle on a large Fangz collagen chew. Like-for-like, 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 across multiple sessions. Hours, not minutes is the floor. You can build a Fangz pack matched to your dog's size so you're getting the full duration out of every chew.
The bigger point is that duration at the cost of tooth safety isn't a trade worth making. A chew that lasts eight hours and causes a fracture has cost you more than a chew that lasts three hours and doesn't.
Head-to-head comparison table
| Factor | Yak chew | Fangz collagen chew |
|---|---|---|
| Typical duration | Hours to days (size/dog dependent) | Hours per session; one chew lasts days to weeks |
| Tooth safety | High fracture risk. Does not soften with saliva. Vet-reported slab fractures. | Tooth-safe. Softens with saliva. Won't fracture teeth. |
| Ingredient count | 3 to 4 (yak milk, cow milk, lime juice, salt) | 3 (beef collagen, beef gelatine, one superfood powder) |
| Protein content | Moderate (dairy-based) | Very high (~93% protein, ~1% fat) |
| Fat content | Moderate to high (dairy fat) | Very low (~1% fat) |
| Digestible? | Generally yes, but dairy may not suit all dogs | Yes. Collagen is a protein the body readily processes. |
| Suitable for sensitive stomachs? | Not ideal if dairy-sensitive | Yes (Pumpkin and Spirulina flavours especially) |
| Puppy-safe? | Generally not recommended under 6 months | Yes, from 4 months old |
| Senior dog safe? | Risky for worn or compromised teeth | Yes. Softening action is gentler on older teeth. |
| What happens at end-nub? | Becomes a small hard disc. Swallowing risk if too small. Some brands advise discarding. | Softens as it gets smaller. Digestible throughout. |
| Odour | Low but present (some owners notice a smell) | Odourless |
| Price-per-hour relative | Moderate (lasts long, but higher fracture downside) | Competitive once fracture cost is removed from the equation |
| Australian-made? | No. Imported, predominantly from Nepal / USA. | Yes. Made in Brisbane by Helen and John. |
What happens at the end of a chew? The nub problem.
This is a question most comparison articles skip. What happens when the chew gets small?
With a yak chew, the end-nub is still hard. Some brands say you can microwave it to puff it up (it becomes a crispy snack). Others recommend taking it away once it's small enough to be a swallowing hazard. Either way, you're dealing with a hard object that doesn't reduce safely on its own.
With a Fangz collagen chew, the nub softens as it gets smaller. Because the whole structure is collagen and gelatine, the dog is slowly consuming a digestible material throughout. There's no hard shard. The chew reduces itself.
This matters for supervision requirements. It's not that you should leave any dog unattended with a chew. But a collagen nub that softens is a fundamentally different risk profile to a hard dairy disc.
Are yak chews digestible?
Yak chews are largely digestible, but they come with two caveats. First, they're dairy-based, so dogs with lactose sensitivity can have digestive upset. Second, a swallowed chunk from a hard yak chew (not a small nub, but a larger piece broken off) passes through the GI tract differently to a piece of softened collagen. Collagen is a protein. It digests. A chunk of compressed milk may not break down cleanly.
Collagen chews are digestible throughout. Beef collagen and beef gelatine are proteins the dog's body processes straightforwardly. The low fat content (~1%) means no grease and no digestive load.
Which is better for power chewers?
For aggressive chewers, the temptation is always to go harder. If your Staffy destroys everything in minutes, the instinct is to find the hardest chew available. Yak chews (and antlers, and Nylabones) end up in the shopping cart for exactly this reason.
That logic breaks down when you factor in what "hard" costs. The harder the object, the higher the fracture risk on a dog that applies serious chewing force.
A better frame: you want density, not hardness. Air-dried collagen is dense. Your dog has to work at it. It won't fracture. That's the right combination for a power chewer. Pick the right size for your dog on the Fangz Build Your Pack page.
For a full breakdown on this, see our guide to dog chews for aggressive and power chewers.
Which is better for sensitive dogs?
Collagen chews win here. Yak chews are dairy-based, which immediately disqualifies them for dogs with dairy or lactose sensitivity. They also tend to score higher on hardness, which matters for dogs with existing dental work, worn teeth, or gum issues.
Our collagen chews come in four flavours, two of which (Pumpkin and Goat's Milk) are specifically chosen for digestive gentleness. Pumpkin supports gut motility. Goat's Milk is mild and creamy, typically well-tolerated even by sensitive stomachs. All four are grain-free, preservative-free, and contain no additives. See all flavours and sizes on the Fangz Build Your Pack page.
Which is better for puppies?
Yak chews are generally not recommended for puppies. Puppy teeth are still developing and the hardness risk is amplified when enamel isn't at full density.
Our collagen chews are suitable from 4 months old. The softening-with-saliva property that makes them tooth-safe for adult dogs is equally relevant for puppy teeth. The 3-ingredient formula (no artificial preservatives, no fillers, no additives) is appropriate for a developing digestive system.

The honest case for yak chews (and where they fall short)
Yak chews are not a scam. They are made from a real animal protein (milk), they are largely natural, and many dogs love them. If you have a gentle chewer with excellent dental health who has never fractured a tooth, the fracture risk is lower (though not zero).
Where they fall short:
- Hardness is non-negotiable. Yak chews do not soften. That's the structural problem.
- They're imported. Most yak chews are produced in Nepal, processed in the USA, and shipped to Australia. We make ours in Brisbane.
- Dairy exclusion. Any dog with dairy sensitivity is automatically out.
- The nub. You have to manage it separately. With a collagen chew, you don't.
- Power chewers crack them. Ironically, the dogs yak chews seem built for are the dogs most at risk from them. High chewing force plus unyielding hardness is the fracture equation.
Where Fangz isn't the answer
We'd rather tell you this than have you buy the wrong thing.
We're not the cheapest chew on the market. A supermarket dental stick costs less per unit. If you're treating a dog who eats a chew in three bites regardless, we might not be the right fit either (though the right size solves this in most cases).
We're small-batch and handmade in Brisbane, so stock can run low between batches.
And if your dog is a gulp-swallower rather than a chewer, no chew is the right answer until you've worked on chew behaviour.
The verdict
For most dogs, collagen chews are the better choice over yak chews on every metric that matters: tooth safety, ingredient simplicity, digestibility, and suitability across life stages. The one area yak chews compete on (duration) doesn't justify the fracture risk.
For power chewers, senior dogs, puppies, and dairy-sensitive dogs specifically, collagen chews aren't just better. They're the only sensible option.
