The Mysterious Carpal Pad
Unlike the other paw pads, the carpal pad sits higher up on your dog’s front legs, around the wrist, and normally doesn’t even touch the ground while walking.
So what is it doing there?
It comes into play when your dog needs extra grip — like when running downhill, moving across a slippery surface, or suddenly slowing down.
The pad can press against the ground, providing extra traction and helping your dog maintain balance. That’s why it’s sometimes called the “stopper pad” — basically, a small built-in brake.
It can even provide extra support when a dog crouches or crawls close to the ground.
Is Your Dog Left-Pawed or Right-Pawed?
And paws can reveal something else about your dog too — whether they prefer their left side or their right.
Just like humans can be left-handed or right-handed, many dogs show a preference for one paw. Research suggests that around two-thirds of dogs show either a left- or right-paw preference, while the rest use both more equally.
There are a few simple ways to test this at home.
One is the Kong Test: just stuff a Kong toy with treats, place it on the floor, and watch which paw your dog uses to hold it steady.
Another is the Food-Reach Test: place a treat just out of reach under something such as a low piece of furniture and see which paw your dog uses to fish it out.
Of course, one attempt doesn’t prove much, so the best way is to repeat the test several times and see whether the same paw keeps winning.
Dogs Walk on Their Toes
And whichever paw your dog prefers, there’s an interesting fact about the way they use all four of them, because dogs actually walk on their toes.
Humans are plantigrade, meaning we walk with our whole foot on the ground. But dogs are digitigrade — their heels stay raised, and their weight is supported mainly by their toes.
It’s basically as if you spent your entire life walking around on the balls of your feet.
This leg structure helps dogs move quickly and efficiently — but it also means that every step, sprint and jump puts a lot of force through a relatively small area.
And that’s where those thick paw pads become extremely important.
Built-In Shock Absorbers
The digital pads under each toe, together with the larger central pad, act like built-in shock absorbers. They cushion the impact every time your dog walks, runs, jumps, or lands, helping protect the bones and joints higher up the leg.
Underneath that tough outer surface is a layer of fatty tissue that helps absorb and distribute some of those forces.
So in a way, your dog is walking around with its own pair of biological running shoes.
But cushioning isn’t the only job these pads have — because they can also do something you probably wouldn’t expect from a dog.
Dogs Sweat Through Their Paws
They can sweat.
Yes, dogs actually sweat — just not quite like we do.
They have sweat glands in their paw pads, which can release moisture when they’re hot or even stressed. That’s why you might occasionally notice damp paw prints on the floor out of nowhere.
And interestingly – paw pads are the only place on the whole dog which can actually sweat!
But sweating through four small paws isn’t nearly enough to cool the whole body, so dogs still rely mainly on panting to get rid of excess heat.
So now you know that dog paws can release moisture – but did you know they can also release scent?
Secret Scent Messages
Dogs have scent-producing glands around their paws, and when they scratch the ground after peeing or pooping, they may be doing more than just kicking up grass.
The scratching can help spread their scent onto the ground while also leaving a visible mark behind.
So when your dog starts furiously scraping the grass after doing their business, they may actually be leaving a kind of signature for other dogs.
And from scent-marking paws, we move to another strange feature almost every dog has — webbing between the toes.
Your Dog Has Webbed Feet
All dogs have some connective skin between their toes, but in certain breeds it’s much more pronounced.
Dogs like Newfoundlands, Labrador Retrievers, and Portuguese Water Dogs have especially noticeable webbing, which helps their paws push against more water with each stroke.
It’s basically the same principle as wearing swim fins.
But webbing isn’t the only way paw shape can help a dog move through difficult terrain.
Built-In Snowshoes
Sometimes, simply having enormous paws can be an advantage.
Cold-climate breeds like the Newfoundland and Saint Bernard have large, broad feet that spread their weight over a bigger surface area.
That makes it easier to move across snow without sinking as deeply — almost like wearing a natural pair of snowshoes.
And paw size isn’t the only thing that varies between breeds.
Cat Feet vs. Hare Feet
Even the basic shape of a dog’s foot can be completely different — so different, in fact, that breeders actually describe them as cat feet and hare feet.
Dogs with cat feet have short, compact, rounded paws with tightly grouped toes. Breeds like the Akita, Doberman, and Giant Schnauzer are known for this type of foot.
Hare feet are almost the opposite. They’re longer and more elongated, with the two middle toes extending farther forward. You can see this shape in breeds like Greyhounds, Borzois, and Samoyeds.
And when you put the compact cat feet of a Doberman next to the long hare feet of a Greyhound, they almost look like they belong to two completely different animals.
But all paw shapes have on thing in common.
The Frito Feet Mystery
They can smell like corn chips.
Dog owners even have a name for it: “Frito feet.”
The smell comes from the normal community of microorganisms living on your dog’s skin. Bacteria — especially types such as Pseudomonas and Proteus — and possibly yeast can produce that distinctive corn-chip-like odor.
And paws are the perfect place for them. They’re warm, they can stay moist between the toes, and as we already learned, dogs even sweat through their paw pads.
A mild Frito smell is usually completely normal. But if the smell suddenly becomes much stronger, especially together with redness, itching, swelling, or constant licking, it can be a sign that something is wrong.
And while those warm paws are a great home for microbes, they also contain a surprisingly clever system for dealing with the exact opposite problem — extreme cold.
The Secret Heating System in Dog Paws
Inside a dog’s paw, small arteries carrying warm blood toward the pads run very close to veins carrying colder blood back toward the body.
This creates what’s called a counter-current heat exchanger. Some of the heat from the outgoing blood is transferred to the colder returning blood before it can be lost through the paws.
In other words, dogs can recycle some of their own body heat.
It doesn’t make their paws immune to frostbite or extreme temperatures, but it helps explain how dogs can spend surprisingly long periods walking and running on snow.
So far, we covered almost every part of the dogs paw - but there’s still one part of the paw we haven’t really talked about — the strange little extra toe sitting off to the side.
Dewclaws Aren’t Useless
The dewclaw.
It’s sometimes described as a useless leftover, but that isn’t really true — especially on the front legs.
Front dewclaws are usually connected by bone, tendons, and muscles, and dogs can use them to help grip objects like bones and toys. They can also provide extra stability and traction during fast turns or when climbing over uneven terrain.
And some breeds take dewclaws even further.
Great Pyrenees, Beaucerons, Briards, and several other breeds can have double dewclaws on their rear legs. In working breeds developed for mountains and rough terrain, these extra toes are thought to have provided additional stability and grip — and in several breeds, they eventually became part of the breed standard.
But even double dewclaws start to look pretty normal when you see the paws of one very unusual dog breed.
The Six-Toed Dog
The Norwegian Lundehund – which was developed to climb steep Norwegian cliffs while hunting puffins, and its paws are unlike those of almost any other dog.
Instead of the usual four weight-bearing toes, Lundehunds have at least six toes on each foot — and several of those extra toes are fully functional, with their own joints, muscles, and tendons.
Together with their unusually flexible body, those extra toes helped them grip narrow ledges and climb across rough, rocky terrain.
And believe it or not, the paws aren’t even the strangest thing about this breed. But this goes far beyond our todays topic – the paws.
