Dogs are lovable companions, but they occasionally exhibit behaviors that baffle and sometimes disgust their owners. One such behavior is eating their own (or others’) dog's poop, a condition known as coprophagia. While this habit might seem revolting, it is relatively common among dogs. Understanding the reasons behind this behavior and how to address it is key to ensuring your furry friend’s health and happiness.

Understanding Coprophagia in Dogs

Definition and Prevalence

Coprophagia, also known as stool eating, is a behavior where dogs consume their own feces or the feces of other animals. According to the American Kennel Club, up to 20% of dogs engage in coprophagia at some point in their lives. This behavior is more prevalent in puppies and young dogs, but it can also occur in adult dogs. While it may seem alarming, understanding why dogs eat feces can help pet owners address and manage this behavior effectively.

Why Do Dogs Eat Dog Poop?

Dogs engage in coprophagia for a variety of reasons, ranging from natural instincts to medical issues. Here are some common explanations:

  1. Instinctual Behavior

    • In the wild, dogs and their relatives often eat feces to keep their dens clean and reduce the risk of attracting predators. This survival instinct may persist in domestic dogs.

  2. Nutritional Deficiency

    • A diet lacking in essential nutrients or enzymes can lead dogs to seek out alternative sources of nutrition, including feces. Malabsorption issues or a poor-quality diet might trigger this behavior.

  3. Imitation or Learned Behavior

    • Puppies often mimic their mother’s behavior, including eating feces. Mother dogs instinctively clean their puppies by consuming their waste during the early weeks of life.

  4. Boredom or Stress

    • Dogs that are left alone for long periods, lack mental stimulation, or experience anxiety may engage in coprophagia as a coping mechanism.

  5. Attention-Seeking

    • Dogs sometimes eat poop to elicit a reaction from their owners. If the behavior garners attention, even if it’s negative, the dog may repeat it.

  6. Medical Conditions

    • Underlying health issues such as gastrointestinal problems, parasites, diabetes, or thyroid disease can cause coprophagia. If your dog’s behavior is sudden or persistent, consult a veterinarian.

A Dog’s Diet and Nutrition

A dog’s diet and nutrition can significantly influence their tendency to eat feces. Dogs that are fed a high-fiber diet or have gastrointestinal issues may be more prone to this behavior. Additionally, dogs that are malnourished or have nutritional deficiencies might engage in coprophagia as a way to supplement their diet. Ensuring your dog receives a balanced and nutritious diet that meets all their nutritional needs is crucial. Consult your veterinarian to determine the best diet for your dog and address any potential dietary deficiencies.

Why It’s Important to Address Coprophagia

Eating feces can expose your young or adult dog to harmful bacteria, parasites, and toxins. It may also lead to secondary health issues like vomiting, diarrhea, or intestinal infections. Additionally, the habit is unsanitary and can create unpleasant situations for pet owners.

Dogs infected with various contagious diseases, such as canine distemper and leptospirosis, can suffer severe health risks. These infections can occur through exposure to virus particles or contaminated environments, emphasizing the importance of vaccination for prevention.

When dogs eat feces, they risk exposure to harmful infections, parasites, and toxins that can negatively impact their health. The specific risks depend on the type of feces consumed (their own, another dog’s, or another species’). Below are the most common infections and health risks associated with coprophagia:

1. Bacterial Infection

  • Salmonella: Dogs can contract salmonella by consuming feces from infected animals, leading to diarrhea, vomiting, fever, and abdominal pain. Severe infections may also cause difficulty breathing.

  • E. coli: Some strains of E. coli can cause upset in the gastrointestinal and digestive tract, including diarrhea and dehydration throughout the dog’s body.

  • Campylobacter: This bacterium can lead to severe diarrhea, abdominal cramps, and fever in dogs.

2. Parasitic Infections

  • Roundworms (Toxocara spp.): Feces from infected animals may contain roundworm eggs, which can cause gastrointestinal distress, malnutrition, or a pot-bellied appearance.

  • Hookworms (Ancylostoma spp.): Dogs can contract hookworms through ingestion, leading to anemia, lethargy, and diarrhea.

  • Whipworms (Trichuris spp.): Whipworms can cause chronic diarrhea, weight loss, and general discomfort.

  • Coccidia: This microscopic parasite is common in feces and can lead to severe diarrhea, dehydration, and lethargy.

  • Giardia: Dogs ingesting infected feces may develop watery diarrhea, abdominal pain, and weight loss. Parasites can significantly affect the dog's body and overall health, necessitating prompt veterinary care.

3. Toxoplasmosis

  • Feces from infected cats can contain the parasite Toxoplasma gondii. While most healthy adult dogs show no symptoms, immune-compromised dogs can experience severe complications, including fever, neurological issues, and lethargy.

4. Fungal Infections

  • Histoplasmosis: Dogs that eat feces contaminated with bird or bat droppings may contract histoplasmosis, a fungal infection that can cause respiratory and gastrointestinal issues.

5. Viral Diseases

  • Parvovirus: Although more commonly spread through direct contact with contaminated surfaces or feces, ingesting the feces of an infected dog can transmit this highly contagious and potentially fatal virus.

  • Distemper: Rarely, the virus could spread through contact with infected fecal matter, especially in unhygienic environments.

6. Intestinal Blockages and Toxins

  • Foreign Material: Feces may contain inedible objects, hair, or indigestible substances that could lead to intestinal blockages and difficulties having a bowel movement.

  • Toxins: Feces from animals exposed to medications, toxins, or certain foods (like chocolate) can be harmful to dogs and cause loose stool or blockages in the digestive tract. Loose stools can also be a symptom of ingesting toxins.

7. Zoonotic Risks (Human Health Concerns)

In addition to risks for dogs, certain infections like salmonella or giardia are zoonotic, meaning they can be transmitted to humans if hygiene is not maintained after a dog engages in coprophagia.

How to Minimize the Risk:

  • Prompt Cleanup: As a pet owner, remove feces from your yard or environment immediately.

  • Prevent Access: Use barriers or dog-proof litter boxes to restrict access to feces.

  • Regular Deworming: Keep your dog\u2019s deworming schedule up to date as advised by your veterinarian.

  • Veterinary Checkups: If your dog frequently eats feces or another dog’s stool, consult a vet to screen for potential infections or parasites.

By addressing coprophagia promptly and maintaining good hygiene, you can protect your dog from these potential health hazards.

Coprophagia can occur in any breed of dog, but studies and anecdotal evidence suggest that some breeds may be more prone to this behavior due to their temperament, instincts, or dietary needs. While no breed is universally exempt, the following factors and breeds are often associated with a higher likelihood of eating poop:

Environmental Factors

Environmental factors can also play a role in coprophagia. Dogs that are kept in unsanitary conditions or are exposed to the feces of other animals may be more likely to engage in this behavior. Additionally, dogs that are not provided with adequate exercise or mental stimulation may resort to eating feces out of boredom or stress. Keeping your dog’s living area clean and providing them with plenty of exercise and mental stimulation can help prevent coprophagia. A well-stimulated dog is less likely to engage in undesirable behaviors.

Breeds More Likely to Eat Dog Poop

  1. Labrador Retrievers

    • Labradors are highly food-motivated, and their eagerness to eat anything resembling food can lead to coprophagia.

  2. Golden Retrievers

    • Like Labradors, Golden Retrievers are often highly motivated by food, making them more likely to consume feces.

  3. Beagles

    • Known for their powerful sense of smell and scavenging behavior, Beagles may eat poop out of curiosity or instinct.

  4. Terriers (e.g., Jack Russell, Yorkshire)

    • Terriers are energetic and inquisitive, which can sometimes result in exploring and consuming unusual objects, including feces.

  5. Shih Tzus and Other Small Breeds

    • Smaller breeds (like a cocker spaniel or a toy breed) might eat poop if they are stressed, under-stimulated, or not receiving a well-balanced diet.

  6. Dogs from Working or Hunting Lines

    • Dogs bred for work or hunting (e.g., German Shepherds, Coonhounds) may exhibit a heightened drive to consume anything with a strong smell, including feces.

Factors Over Breeds

While breed can play a role, individual behavior and environment are often more significant predictors of coprophagia. Factors like nutritional deficiencies, boredom, stress, or learned behaviors influence the likelihood of this habit.

Addressing the Behavior When a Dog Eats Dog Poop

If your dog is eating poop, regardless of breed, focus on:

  • Providing a balanced dog's diet to ensure their digestive health.

  • Offering mental and physical stimulation.

  • Cleaning up waste promptly.

  • Training with positive reinforcement.

  • Giving your dog a bath immediately and cleaning thoroughly around their mouth with the appropriate grooming and cleaning products.

If the behavior persists, consult a veterinarian or a canine behaviorist to address potential underlying medical or psychological issues.

Supervision and Cleanup

Supervision and prompt cleanup are crucial in preventing coprophagia. Always supervise your dog during bowel movements and immediately clean up any feces to prevent them from eating it. This can be especially challenging for pet owners who have multiple dogs or live in areas with limited space. However, consistent supervision and cleanup can significantly reduce the likelihood of your dog eating feces. By maintaining a clean environment, you can help keep your dog healthy and discourage this behavior.

Redirection and Distraction

Redirection and distraction are effective strategies to prevent coprophagia. You can redirect your dog’s attention away from feces by using verbal commands or treats. Additionally, distracting your dog with toys or other forms of enrichment can prevent them from engaging in this behavior. By using a combination of supervision, cleanup, redirection, and distraction, you can help prevent coprophagia and keep your dog healthy. Training your dog to respond to commands like “leave it” can also be beneficial in managing this behavior.

It’s worth noting that some dog breeds, such as the Cocker Spaniel, may be more prone to coprophagia due to their instinct to follow their noses and eat whatever they find. However, with proper training and management, any dog can learn to avoid eating feces.

In some cases, coprophagia can be a sign of an underlying medical issue, such as a bacterial infection or gastrointestinal problem. If your dog is experiencing persistent or severe coprophagia, it’s essential to consult with a veterinarian to rule out any underlying health issues.

How to Stop a Dog from Eating Poop

Tackling coprophagia requires a multi-faceted approach that addresses the root causes and discourages the behavior. Here are practical strategies:

  1. Provide a Nutrient-Rich Diet

    • Feed your dog high-quality, balanced food to ensure they receive all the necessary nutrients. Consult your veterinarian to address any potential dietary deficiencies.

  2. Clean Up Promptly

    • Regularly clean your yard and remove feces as soon as possible. Preventing access to poop is one of the most effective ways to stop the behavior.

  3. Train and Redirect

    • Teach your dog commands like “leave it” or “come” to redirect their attention away from feces. Reward them with treats or praise for obeying commands.

  4. Increase Physical and Mental Stimulation

    • Ensure your dog gets plenty of exercise and mental enrichment through toys, games, and training. A stimulated dog is less likely to engage in undesirable behaviors.

  5. Use Deterrents

    • Add taste deterrents to your dog’s diet or directly to feces (if safe for both pets). Products like For-Bid or NaturVet discourage poop consumption by making it taste unpleasant.

  6. Address Stress or Anxiety

    • If your dog’s coprophagia is linked to stress or anxiety, identify the triggers and address them. Provide a safe, comforting environment and consider consulting a professional trainer or behaviorist.

  7. Rule Out Medical Issues

    • Schedule a veterinary check-up to rule out any underlying medical conditions. Your vet may recommend supplements, medication, or dietary adjustments if necessary.

Preventing Future Occurrences

Consistency and patience are key when addressing coprophagia. Establish a routine for feeding, exercise, and cleanup, and monitor your dog’s behavior closely. Positive reinforcement for good behavior and a watchful eye can go a long way in preventing recurrences.

When to Seek Professional Help As A Dog Owner

If your efforts don’t yield results, consider consulting a veterinarian, professional dog trainer, or animal behaviorist. Persistent or extreme cases of coprophagia may require specialized intervention. Additionally, monitoring your dog's stool for changes in color, the presence of mucus, or other abnormalities can provide important health indicators that may require veterinary attention.

Final Thoughts

Although coprophagia is a natural behavior for dogs, it’s undesirable and potentially harmful in a domestic setting. By understanding the underlying causes and implementing effective strategies, you can help your dog overcome this habit and ensure their well-being. With proper care, training, and a little patience, you and your dog can move past this unpleasant phase. Additionally, be aware of potential health risks such as kennel cough, which is highly contagious and can be transmitted through contact with infected dogs or shared items.
