Are Air-Dried Bones Safe for Dogs? Why a Chicken Foot Isn't a Femur
"Are those big air-dried bones okay for my dog?"
I get this question all the time, at expos and in our DMs. And it usually comes with a follow-up: "You sell chicken feet. Aren't those bones too?"
They are. Both are bone, both are air-dried, and both can break. The difference is what they break into. That's the whole reason I sell one and not the other.
The answer every supplier gave me
When I was building our range, I looked at stocking big air-dried bones: beef femurs, marrow bones, kangaroo leg bones. They sell well and dogs love them.
So I asked suppliers if they were safe. Every one gave me the same answer: "They're air-dried, not cooked. They won't splinter like cooked bones."
Cooked bones really are worse, that part is true. But "less than cooked" isn't the same as "doesn't splinter." I wanted to understand why.
What drying does to a bone
Fresh bone holds a fair bit of water, and that water lets it flex a little. Dry it out, and researchers who study bone have found the same thing again and again: it gets harder, but it also gets more brittle.
Brittle means it doesn't bend before it breaks. It holds, and holds, and then it cracks. Cooking pushes bone a long way in that direction. Air-drying pushes it the same way, just less far.
So the real question isn't "will this bone break?" Given a determined dog, most bones can. The question is: when it breaks, what does it break into?
Chicken foot vs femur: it's all in how they break
| Chicken foot | Beef femur | |
|---|---|---|
| The bone | Lots of tiny, thin bones | One thick tube of dense bone |
| What's around it | Skin, tendon and cartilage | Nothing; it's bare bone |
| When a dog bites down | Crunches through easily | Usually can't bite through |
| If it breaks | Small pieces, chewed up with the soft tissue | Large, hard pieces with sharp edges |
A chicken feet is mostly skin, tendon and cartilage around very small bones. When your dog crunches down, the bones break into little bits that get chewed and swallowed along with everything else.
A femur is built to hold up an animal weighing hundreds of kilos. It's a thick, dense tube, and drying makes it harder still. Most dogs can only scrape at it. But a strong, determined chewer can crack one, and when that happens, it doesn't crumble. It breaks into big, hard shards.
The ASPCA warns that bone splinters can get stuck in a dog's throat, or damage the gut on the way through.
In 2017, the US FDA looked at reports from owners about bone treats. Here's what it found:
- About 90 dogs fell ill, and around 15 died
- The treats included pork femur bones
- The problems included choking, blockages and cuts in the mouth
- Some owners saw the bones splinter as their dogs chewed
To be fair, those were processed bone treats, not air-dried ones. But drying pushes bone the same way: harder, and more brittle.
Chicken feet aren't zero-risk either. A vet writing for Adopt-a-Pet notes that how chicken feet are dried matters, since high heat makes the bones more brittle, and that dogs who gulp can choke on pieces that are too big. So choose plain, gently dried feet, pick a size that suits your dog, and stay close while they eat.
Gnawer or crusher? It decides who cracks the bone
Next time your dog has a chew, watch for a minute.
Gnawers lie down, hold it between their paws and scrape away slowly. They rarely break big pieces off anything.
Crushers push it to the back of the mouth and bite down hard. You'll hear loud cracks. These are the dogs that actually break big bones, and the dogs most likely to swallow a shard.
If your dog is a crusher, big dried bones are the chew I'd skip first.
What Haru taught me
My Shiba Inu, Haru, is a gnawer, and he did fine on hard chews when he was younger.
As he got older, his gums started bleeding when he chewed them. So we stopped. No more hard chews for Haru. That's common in older dogs. Gum problems get more likely with age, and bleeding gums are one of the signs.
Why every hard chew on our store has a note
I do sell hard chews: goat horn and yak chew. For a patient gnawer, they're great.
But a while back, a customer messaged me about a year after buying one of our yak chews. Their dog had cracked a tooth.
After a whole year, there was no way to know what caused it. But "you can't prove it was us" didn't sit right with me. So every hard chew on our store now carries a note: choose based on what your dog needs and can handle, and don't buy a hard chew just because it lasts long.
(And since people ask: our Bone Marrow chew has no bone in it. It's made from marrow. Totally different from the marrow bones above.)
If your dog already loves bones
- Take it away once it's small enough to swallow, or once pieces start breaking off.
- Know the warning signs of a swallowed shard. The FDA lists choking, vomiting, diarrhoea and blood in the stool. If you see any of these after a bone, call your vet.
- Don't just swap to an antler or a hoof. They're just as hard.
- Stay in the room whenever your dog has a chew.
So, are air-dried bones safe?
Not all bones are equal. Small, thin bones wrapped in soft tissue, like chicken feet, break into small pieces. Big, thick bones like beef femurs and kangaroo leg bones can break into large, sharp shards, and they're hard on teeth too. That's why I sell chicken feet, soft bone and not femurs.
Whatever you choose, choose it for your dog: how they chew, how old they are, and what their mouth can handle.
Not sure what suits yours? Send us your dog's weight, age and how they go at a chew. I'll tell you honestly which of ours fits, or if none of them do.
