Why Does My Dog Eat Poop? Causes and What Actually Helps

Coprophagia, eating faeces, is one of the more unpleasant behaviours French Bulldog owners encounter. It ranges from occasional puppy curiosity to a persistent habit that resists most interventions. Understanding whether the cause is dietary, medical, behavioural or simply opportunistic determines what approach is likely to work.

Types of coprophagia

Autocoprophagia: Eating their own faeces. Most common and most studied.

Interspecific coprophagia: Eating the faeces of other species. Cat litter box raiding is the most common example in UK homes; eating rabbit, horse or fox droppings when out on walks is also frequent.

Intraspecific coprophagia: Eating the faeces of other dogs. Less common in domestic situations where dogs defecate outdoors, but seen in multi-dog households.

The management approach differs by type.

Medical causes

Before assuming the behaviour is purely behavioural, certain medical causes should be considered, particularly in adult dogs where the behaviour has started suddenly or alongside other digestive signs.

Malabsorption and exocrine pancreatic insufficiency (EPI)

In malabsorption conditions, nutrients are not properly absorbed in the small intestine. The faeces still contain partially digested or undigested food material, which smells and tastes appealing to the dog. EPI, a condition where the pancreas does not produce sufficient digestive enzymes, causes exactly this pattern: ravenous appetite, weight loss despite eating well, pale or greasy stools, and eating faeces.

EPI is diagnosable with a simple blood test (trypsin-like immunoreactivity / TLI test) and is manageable with enzyme supplementation. If a French Bulldog has persistent loose stools, poor body condition, high appetite and coprophagia, a vet check to rule out EPI is worthwhile before assuming the behaviour is purely habitual.

Intestinal parasites

Heavy parasite burden can increase appetite and cause malabsorption. Keeping deworming up to date is basic preventive care.

Nutritional deficiency

Dogs fed nutritionally inadequate diets may develop unusual appetite behaviours including coprophagia. This is less common with commercially complete diets but can occur with homeprepared diets that are not properly balanced.

Behavioural causes

Maternal behaviour

Dams clean their puppies by licking, including consuming the puppies’ faeces and urine to keep the whelping area clean. Puppies may observe and learn this behaviour. Some dogs retain it into adulthood. This is one of the more common routes to adult autocoprophagia.

Attention-seeking and reinforcement

A puppy that eats poop generates an immediate, often animated response from the owner. That response, even if negative, is rewarding for a socially motivated puppy. The behaviour can become established through this inadvertent reinforcement. The characteristic pattern: the behaviour occurs primarily when the owner is present and stops when the owner is absent (because the reinforcement is absent).

Removing the reward (not reacting) and ensuring prompt stool removal is the management approach.

Anxiety and stress

Some dogs engage in coprophagia as a displacement or self-soothing behaviour in response to stress, confinement anxiety, separation anxiety or environmental stress can all contribute. The behaviour appears or increases in stressful contexts.

Habit and opportunity

Some dogs simply find faeces palatable and eat them when available. This is the category most resistant to dietary supplements and supplements. Management, ensuring that faeces are not left accessible, is the most reliable intervention.

What actually helps

Prompt stool removal

The most effective single intervention is removing faeces before the dog can access them. In the garden, go outside with the dog and collect the stool immediately. On walks, moving away from deposited faeces quickly reduces opportunity. This works regardless of the cause.

Dietary review

Ensure the dog is on a complete, nutritionally adequate diet. If the diet is homeprepared or raw, have it reviewed by a veterinary nutritionist. If malabsorption is suspected, vet investigation is appropriate.

Not reacting

For attention-seeking coprophagia: no reaction when the dog approaches faeces. Calmly redirecting the dog away or quietly intervening to prevent access without providing animated interaction.

Training “leave it”

A reliably trained “leave it” cue allows the owner to interrupt the behaviour before it occurs. This takes consistent training across many low-stakes situations before it generalises to the garden context, but it is one of the most practically useful interventions for dogs where the behaviour is opportunity-driven on walks.

Deterrents

Products added to food to make faeces unpalatable (including some commercial preparations and folk remedies like pineapple) have variable and generally unreliable results. They occasionally help when the behaviour is driven by palatability; they do not address habit, anxiety or attention-seeking causes. Worth trying if other approaches are in place, but not a standalone solution.
