Why Do Dogs Eat Poop? Exploring the Causes and Solutions

Have you ever caught your beloved furry friend in the act of eating poop? It may seem like a strange and disgusting behavior to us, but for dogs, it’s actually quite common. In this article, we’ll explore the various causes of coprophagia, or poop eating, in dogs and provide solutions on how to prevent this behavior.

Understanding Coprophagia in Dogs

Coprophagia is a behavior that has puzzled dog owners for years. The act of a dog consuming the feces of another animal, including their own, is not only unpleasant but can also be a health risk. However, it’s important to note that not all dogs engage in this behavior, and it’s not a sign of any underlying psychological issues. In fact, many dogs who eat poop are completely healthy and well-adjusted.

What is Coprophagia?

Coprophagia can be traced back to the ancestral behavior of wild dogs and their need to consume all available resources, including food and waste. For domesticated dogs, this behavior can be triggered by a variety of factors, including stress, nutritional deficiencies, and boredom. It’s important to understand that this behavior is not a sign of a dog being “dirty” or “disgusting,” but rather a natural instinct that some dogs have.

Common Reasons for Coprophagia in Dogs

While coprophagia can be caused by a range of factors, the most common reasons include:

  • Imitation – Some dogs may learn the behavior from other dogs or from watching their owners clean up after them. This is especially common in puppies and younger dogs who are still learning appropriate behavior.
  • Curiosity – Puppies and younger dogs may explore the world around them, including poop. This behavior is often a result of their natural curiosity and desire to investigate their environment.
  • Inadequate nutrition – Dogs that are not receiving the proper nutrients may turn to feces to satisfy their cravings and dietary needs. This is especially common in dogs that are fed a poor-quality diet or are not receiving enough food.
  • Boredom – Dogs that lack mental stimulation and exercise may engage in coprophagia as a form of entertainment or distraction. This behavior is often seen in dogs that are left alone for long periods of time or are not given enough opportunities to play and exercise.
  • Anxiety – Dogs that are anxious or stressed may eat poop as a coping mechanism. This behavior is often seen in dogs that have experienced trauma or have separation anxiety.

If you suspect that your dog is engaging in coprophagia, it’s important to speak with your veterinarian. They can help rule out any underlying health issues and provide recommendations for managing the behavior. It’s also important to keep your dog’s environment clean and provide them with plenty of mental stimulation and exercise to prevent boredom and anxiety.

Causes of Poop Eating in Dogs

While the reasons for a dog’s coprophagia behavior can vary, the causes can be broadly categorized into the following five areas:

Nutritional Deficiencies

Dogs that are not receiving adequate nutrition may resort to eating poop as a way to supplement their diet. A lack of digestive enzymes, fiber, and other essential nutrients can cause a dog to feel hungry and seek out alternative sources of food. It is important to ensure that your dog is receiving a balanced and nutritious diet to prevent coprophagia from developing due to nutritional deficiencies. Consult with a veterinarian to determine if your dog’s diet needs to be adjusted.

Boredom or Anxiety

Dogs that are left alone for extended periods of time without stimulation may become bored and anxious. To alleviate these feelings, they may turn to eating poop as an activity. This can be especially true for dogs with separation anxiety. It is important to provide your dog with plenty of exercise, playtime, and mental stimulation to prevent boredom and anxiety. Consider hiring a dog walker or pet sitter to provide your dog with additional attention and activity during the day.

Health Issues

A variety of health issues can lead to coprophagia in dogs. These can range from digestive problems to dental issues. Dogs with malabsorption or other digestive issues may turn to poop as a way to gain nutrition from their waste. Similarly, dental problems such as tooth decay and gum disease can make it difficult for a dog to eat properly and may cause them to seek out alternative sources of food. Regular veterinary checkups and dental cleanings can help prevent these health issues from developing and causing coprophagia.

Environmental Factors

The environment in which a dog is kept can have a significant impact on their behavior, including coprophagia. Dogs that are kept in small spaces with limited access to the outdoors may be more likely to eat poop out of boredom or lack of stimulation. Similarly, dogs that are kept in unclean conditions may become accustomed to consuming waste as a result of their environment. Providing your dog with a clean and spacious living environment, as well as plenty of outdoor time and exercise, can help prevent coprophagia caused by environmental factors.

Learned Behavior

Dogs may learn to eat poop from other dogs or from their owners. If a dog sees another dog engaging in coprophagia, they may attempt to mimic that behavior. Similarly, if an owner punishes their dog for defecating in the wrong place, the dog may feel the need to consume their feces to avoid punishment. It is important to train your dog using positive reinforcement techniques and to discourage coprophagia behavior through redirection and other training methods.

In conclusion, coprophagia is a common behavior in dogs that can have a variety of causes. By understanding the potential reasons for this behavior and taking steps to prevent it, you can help ensure your dog’s health and happiness.

Dangers of Poop Eating in Dogs

While coprophagia may be a natural behavior for some dogs, it can pose significant health risks. A dog that consumes feces is at risk of ingesting parasites and bacteria that can cause illness. Additionally, some substances, such as chocolate and onion, can be toxic to dogs and may be present in feces.

Parasites and Infections

When a dog eats poop, they are at risk of ingesting harmful parasites and bacteria, including salmonella and E. coli. This can lead to digestive issues, such as vomiting and diarrhea, and may require medical attention. Additionally, some worms and parasites can be transmitted through feces, increasing the risk of infection.

One example of a parasite that can be transmitted through feces is roundworm. Roundworm eggs can be present in the feces of infected dogs and can survive in the environment for long periods of time. When a dog eats contaminated feces, they can become infected with roundworms, which can cause a variety of symptoms, including vomiting, diarrhea, and weight loss. In severe cases, roundworms can cause intestinal blockages, which may require surgery to correct.

Toxic Substances

Some substances that are toxic to dogs can be present in feces. Chocolate, onions, and other human foods can be harmful to dogs and may be present in the waste of other animals. Additionally, feces that have been treated with chemicals, such as pesticides, can pose a risk to dogs if ingested.

In addition to chocolate and onions, there are other foods that can be harmful to dogs if ingested. Grapes and raisins, for example, can cause kidney failure in dogs. Avocado, macadamia nuts, and garlic are also toxic to dogs and should be avoided. When a dog eats feces that contains these substances, they can become ill and may require veterinary care.

Dental and Digestive Problems

Continuously eating feces can cause dental and digestive problems in dogs. The high concentration of bacteria and harmful substances in feces can lead to tooth decay, gum disease, and other health issues. Additionally, consuming feces can lead to blockages in the digestive tract, particularly if the poop is not fully digested.

There are several steps that dog owners can take to prevent coprophagia in their pets. One approach is to keep the dog’s environment clean and free of feces. This can be accomplished by regularly cleaning up after the dog and using a leash to keep the dog away from areas where other animals may have defecated. Additionally, providing the dog with plenty of exercise and mental stimulation can help reduce the likelihood of coprophagia.

In conclusion, while coprophagia may be a natural behavior for some dogs, it can pose significant health risks. Dog owners should take steps to prevent their pets from eating feces in order to protect their health and well-being.

How to Prevent Your Dog from Eating Poop

Preventing coprophagia requires a multi-faceted approach that addresses the underlying causes of the behavior. Below are some tips on how to prevent your dog from eating poop:

Addressing Nutritional Needs

Ensuring that your dog receives a well-balanced diet that meets their nutritional needs can help prevent coprophagia. Consult with your veterinarian if you suspect that your dog may have nutritional deficiencies.

It is important to note that some dogs may eat poop because they are not getting enough nutrients from their food. This can be caused by a poor quality diet or a lack of absorption of nutrients due to an underlying health condition. Therefore, it is essential to provide your dog with a balanced and nutritious diet that is appropriate for their age, breed, and activity level.

Providing Mental Stimulation and Exercise

Boredom and anxiety can lead to coprophagia. Providing your dog with regular exercise and mental stimulation through games, toys, and training can help prevent this behavior.

Dogs are intelligent animals that require mental stimulation to keep them happy and healthy. Without proper stimulation, dogs can become bored and anxious, which can lead to destructive behaviors such as coprophagia. Therefore, it is important to provide your dog with plenty of opportunities for exercise and play, as well as mental stimulation through training and interactive toys.

Training and Behavior Modification

Training and behavior modification techniques, such as positive reinforcement, can help prevent coprophagia in dogs. Working with a professional trainer or behaviorist can help you develop a plan that addresses your dog’s specific needs.

Positive reinforcement training is a highly effective way to modify your dog’s behavior. This involves rewarding your dog for good behavior, such as coming when called or not eating poop, with treats, praise, or playtime. By focusing on positive reinforcement and avoiding punishment, you can build a stronger bond with your dog and help prevent undesirable behaviors such as coprophagia.

Environmental Management

Making changes to the environment in which your dog lives can help prevent coprophagia. This may include providing access to the outdoors or increasing the amount of space in which your dog can move around.

Dogs that are confined to small spaces or do not have access to the outdoors may be more likely to engage in coprophagia. Therefore, it is important to provide your dog with plenty of space to move around and access to the outdoors. Additionally, keeping your dog’s living space clean and free of feces can help prevent the behavior.

Using Taste Deterrents

Taste deterrents can be used to discourage your dog from eating poop. These products, such as bitter apple spray, can be applied to feces to make them less appealing to dogs.

Taste deterrents can be a useful tool in preventing coprophagia, but they should be used in conjunction with other preventative measures. Additionally, it is important to choose a taste deterrent that is safe for your dog and does not cause any adverse reactions.


In summary, coprophagia is a common behavior in dogs that can have a range of causes and pose significant health risks. Preventing this behavior requires a multi-faceted approach that addresses the underlying causes and encourages healthy behaviors. By working with your veterinarian and a professional trainer, you can help ensure that your dog stays healthy and happy.
