Your dog finishes, then kicks both back legs dramatically, throwing up grass and soil, occasionally the front legs too, and walks off looking extremely pleased.
Almost everyone assumes it is an attempt at burying. It is close to the opposite.
The equipment nobody knows about
Dogs have interdigital glands between their toes and in the pads of their feet. These produce pheromones — chemical signals carrying information about the individual animal.
When a dog scrapes its back legs, it is pressing those glands into the ground and dragging them across it, depositing scent over a much larger area than a urine mark alone.
So the kicking is not covering the mark. It is adding a second, different mark on top of it, and spreading the whole message over a wider patch.
What the message says
Scent marking in dogs conveys a surprising amount: individual identity, sex, reproductive status, roughly how long ago the animal passed, and possibly something about size and condition.
Ground scratching appears to be a way of amplifying that message. It is seen more often:
- In male dogs than females, though plenty of females do it
- In unneutered dogs more than neutered ones
- After defecation more than after urination
- In the presence of other dogs, or where other dogs have marked
- On surfaces that hold scent well, like grass and soil
The behaviour is not unique to domestic dogs. Wolves, coyotes and foxes all do it, and so do big cats — lions and tigers scrape in a very similar way for very similar reasons.
Why the timing seems odd
Some dogs kick immediately. Some walk several paces first and then scrape, which looks like they have forgotten what they were doing.
That distance is probably deliberate. Spreading the scent over a larger area, in a slightly different spot from the deposit itself, extends the reach of the signal.
Is it showing off?
Partly, in the sense that it is communication aimed at an audience.
Research on ground scratching has found that dogs do it more when other dogs are watching, and more in areas with high dog traffic. Some behaviourists interpret it as a display behaviour with a social component, rather than a purely mechanical marking action.
The enthusiasm varies enormously between individuals. Some dogs treat it as a formality; others put their whole body into it, dig a trench and look around afterwards to see who noticed.
Should you stop it?
Generally no. It is entirely normal behaviour and suppressing normal communication is rarely a good idea.
When it becomes a practical problem:
- On a neighbour’s lawn, where it leaves visible damage. Move the dog on before it starts, or choose your route.
- On hard surfaces, where repeated scraping can wear nails and pads. Most dogs avoid this instinctively.
- When it is obsessive, continuing for long periods or accompanied by other repetitive behaviours.
The practical fix is management rather than correction: recognise the pre-kick pause, and walk on before it begins.
When to look more closely
Scraping is normal. A few related patterns are not.
Also worth checking:
- Licking or chewing at the paws alongside scratching, which may indicate allergies or irritation between the toes
- Limping after scratching, which can mean a damaged nail or a split pad
- Excessive, frantic scraping that does not stop, which occasionally accompanies compulsive behaviour
Earth Rated Dog Wipes
Useful for wiping paws down after a walk, particularly in a dog that scrapes enthusiastically through mud and grit. Check between the toes while you are there.

Look after the feet
Enthusiastic scrapers put wear on their nails and pads.
- Keep nails at a sensible length so they are not catching
- Check pads for splits, especially in winter and on hot pavement
- Check between the toes for grass seeds in summer
gonicc Dog Nail Clippers
Long nails snag and split during vigorous scraping. Trim every three to four weeks and check the dewclaws while you are at it.
Musher's Secret Paw Wax
A barrier wax for pads that take a battering from rough ground, salt or ice. Apply to clean dry pads and let it absorb before the dog walks on carpet.
The bigger picture
Once you know about the interdigital glands, quite a few other behaviours make sense.
Dogs that scratch at doors are leaving scent as well as making noise. Dogs that dig at bedding before lying down are marking it. Dogs that paw at you may be doing something more than asking for attention.
Feet are not just for walking. They are a broadcasting system, and your dog is using it every time it tears up the corner of the park.
