You know the routine.
Your dog finds the perfect patch of grass, circles a few times, does their business… and then suddenly launches into a frantic backwards kicking session, sending grass, soil and sometimes half the garden flying.
It can look like they’re trying to bury their poop.
But that’s probably not what’s happening.
The behavior is known as ground scratching, and researchers have observed it in domestic dogs as well as wild canids. Far from being a pointless post-toilet ritual, it appears to be part of a surprisingly sophisticated system of canine communication.
Your dog isn’t covering it — they’re advertising it
One of the biggest misconceptions about dogs kicking dirt after defecating is that they’re attempting to cover up their waste.
That’s actually more characteristic of some other species, including cats.
For dogs, the evidence points in almost the opposite direction.
Ground scratching can create both chemical and visual signals. As your dog scrapes backwards, they disturb the ground, leaving visible scratches that can remain after the dog has disappeared. At the same time, secretions associated with the paws can contribute additional scent information to the area.
In other words, your dog’s message isn’t necessarily:
“Please don’t notice what I’ve left here.”
It’s potentially closer to:
“I was here.”
And other dogs are very interested in that information.
Dogs live in a world of smells we can barely imagine
Humans experience the world predominantly through sight and sound.
Dogs experience an enormous amount of their environment through smell.
Urine, feces and secretions from various scent-producing glands can all carry chemical information. Dogs can investigate these scents to gather information about other animals that have passed through an area.
Interestingly, research has also demonstrated that dogs possess scent-producing secretions around their paws, and scientists have investigated whether these odors can contribute to individual recognition.
So when your dog scrapes the ground after going to the toilet, they may be adding another layer to an already information-rich scent environment.
Think of it as a canine social-media post
Your dog leaves behind:
The poop:
A chemical message.
The urine:
Another source of scent information.
The paw secretions:
Potentially another individual scent signal.
The scratches:
A visible—and possibly auditory—sign that something happened here.
Researchers describe ground scratching as a composite signal, because it can combine chemical, visual and even auditory elements.
That’s a lot of communication for something that looks like your dog simply having a tantrum with the lawn.
And it isn’t just about territory
It’s tempting to describe the behavior simply as “territorial marking.”
There is evidence for that, but the reality appears to be more nuanced.
Research on free-ranging domestic dogs found that scent-marking behaviors, including ground scratching, could be associated with territorial boundaries and interactions between dogs. The researchers suggested that ground scratching can have roles in both olfactory and visual communication.
Ground scratching has also been observed more frequently around interactions with unfamiliar dogs in some observations.
So your dog isn’t necessarily declaring:
“This is MY garden. Stay away.”
The message could simply be communicating presence, identity or information about the animal that was there.
Male dogs don’t have a monopoly on it
Another interesting fact is that both male and female dogs can ground-scratch.
Research involving shelter dogs found that ground scratching after urination or defecation wasn’t characterized by the same sex differences seen in some other marking behaviors.
That’s important because people often associate scent marking with male dogs.
But the post-poop kick isn’t exclusively a male behavior.
Your female dog launching turf across the lawn isn’t necessarily behaving unusually.
She’s participating in a canine communication behavior that can occur in both sexes.
Some dogs are much more enthusiastic than others
You’ve probably noticed that some dogs give one little kick before walking away.
Others appear to believe they’ve been personally hired to excavate the garden.
There’s considerable individual variation in ground scratching.
Research has found associations between age and some forms of ground scratching, with adult and senior shelter dogs more likely to exhibit the behavior than juveniles.
And dogs don’t necessarily do it every time they urinate or defecate.
Some may scratch after toileting; others may occasionally scratch after simply investigating an interesting scent.
So there’s no requirement for your dog to perform the ritual after every bathroom trip.
Why does the kicking look so dramatic?
Here’s where things get particularly fascinating.
The scratches themselves may have a communicative function.
A dog doesn’t need another dog to be standing there watching when it performs the behavior. The disturbed ground can remain as a visual marker after the dog has moved on.
And because dogs are extraordinarily attentive to environmental scent, another dog passing later may investigate the area.
The result is almost like leaving a signpost:
DOG WAS HERE → SOMETHING HAPPENED HERE → INVESTIGATE.
We shouldn’t overinterpret this as a precise canine sentence—scientists cannot tell us exactly what an individual dog is “saying.”
But the combination of scent and visual marking provides strong evidence that the behavior is communicative rather than simply an attempt to cover feces.
Should you stop your dog from doing it?
Usually, no.
For most dogs, ground scratching is normal behavior.
If your dog is happily kicking grass after toileting and isn’t damaging themselves or causing a serious problem, there’s generally little reason to prevent it.
The situation is different if your dog begins scratching obsessively, repeatedly attacks hard surfaces, or damages their nails or paw pads.
Repeated vigorous scratching on concrete, paving or other abrasive surfaces can potentially cause injury to the feet.
And if the behavior suddenly becomes dramatically more frequent or is accompanied by other unusual changes in behavior, it’s worth discussing with your veterinarian.
The next time your dog kicks up the lawn…
So, when your dog finishes pooping and immediately starts firing chunks of grass behind them, don’t necessarily think:
“Why can’t you just walk away normally?”
From your dog’s perspective, they may not be finished at all.
The toilet break may have been only the first part of the message.
The backward scratching potentially adds scent, leaves visible marks and draws attention to the location—creating a surprisingly sophisticated communication signal that other dogs can investigate long after your dog has trotted away.
And that makes the familiar post-poop kicking ritual much more interesting than it looks.
Your dog may not be trashing the lawn.
They may simply be posting an update!
