Why Puppies Eat Their Own Poop, and How to Break the Habit

In this guide

Few puppy behaviours provoke quite as much disgust from new owners as watching their puppy eat its own stool. Coprophagia, the technical term for it, is unpleasant to witness but usually far less alarming than it feels in the moment, and it is genuinely common, particularly in young puppies.

Where the instinct comes from

Mother dogs routinely eat their puppies' stool for the first few weeks after birth, both to keep the whelping area clean and to protect the litter from the scent alerting predators. Puppies raised around this behaviour sometimes appear to copy it, and general puppy curiosity, exploring everything with the mouth, adds to the habit in the early months.

Other common contributing factors

• Boredom or insufficient mental and physical stimulation
• Anxiety, particularly around confinement or being left alone for long stretches
• A history of being scolded for house training accidents, which can lead a puppy to eat the evidence to avoid a repeat telling off
• Poor digestion, where undigested nutrients in the stool make it smell and taste similar to food
• Multi dog households, where the behaviour is measurably more common than in single dog homes

When it might signal something medical

If an adult dog that has never shown this habit suddenly starts, especially alongside weight loss, changes in appetite, vomiting or diarrhoea, a vet visit is worth arranging to rule out digestive issues such as exocrine pancreatic insufficiency or intestinal parasites, both of which can affect nutrient absorption and drive the behaviour.

What actually helps

• Clean up after your puppy promptly, removing the opportunity is the single most effective step
• Never punish house training accidents, since this can be part of what drives poop eating in the first place
• Keep feeding and toileting areas separate, so a puppy does not associate the smell of stool with food
• Increase daily exercise and mental stimulation to reduce boredom driven behaviour
• Teach a reliable leave it cue and use it proactively during walks, rewarding the puppy for disengaging from stool before it gets close

What generally does not work

Food additives marketed to make stool taste unpleasant have mixed, inconsistent results and are not a substitute for the management steps above. Scolding a puppy after the fact is similarly ineffective, since it does not address any of the underlying drivers and can add anxiety to the mix.

The reassuring part

Most puppies naturally outgrow this behaviour with age, consistent supervision and prompt cleanup, particularly once the instinctive early puppy phase passes. Patience paired with removing the opportunity resolves the vast majority of cases without any need for more elaborate intervention.

A specific risk in households with a cat

Puppies that also have access to a cat's litter box are drawn to it more than most owners expect, and eating cat stool carries a genuine health risk beyond the general unpleasantness, including exposure to toxoplasmosis and other parasites cats can carry. Placing the litter box somewhere the puppy genuinely cannot reach, behind a baby gate with a cat sized gap, on a raised surface, or in a room with a door the puppy cannot open, is worth setting up early rather than trying to manage it through supervision alone.
