Is coprophagia your dog’s dirty little secret? If it is, you (and your dog) are not alone. According various estimates, 10-25% of dogs engage in intraspecies coprophagia—that is, they eat their own or other dogs’ feces.
While in most cases, coprophagia is a behavioral problem, it can also have medical basis. Medical causes of coprophagia include dietary deficits from inadequate intake or absorption of nutrients and increased appetite caused by different diseases or medications. Dogs receiving adequate calories and being fed diets that are “complete and balanced” according to AAFCO standards, should be receiving the nutrients they need unless they have a disease that prevents them from absorbing and retaining nutrients. Exocrine pancreatic insufficiency (EPI) is one disease in which dogs do not have the enzymes they need to properly digest their food. Despite receiving a diet that is complete and balanced, dogs with EPI will often lose weight, act hungry, and lose nutrients in voluminous stools. Dogs with severe liver disease, intestinal parasites, undertreated diabetes mellitus, and some types of gastrointestinal and kidney disease may also not be able to properly absorb and retain nutrients from their food. These deficits can leave dogs hungry and seeking calories and nutrients from nontraditional food sources (feces). Cushing’s Disease or hyperadrenocorticism can increase a dog’s appetite as can steroids or medications given to control seizures. In some cases, these dogs may eat feces as a way to satisfy their hunger.
In the majority of cases, coprophagia is a behavioral rather than a medical problem. Coprophagia is actually a normal behavior in female dogs with puppies. Good dog mothers will lick at their puppies’ rear ends to stimulate defecation and will consume puppies’ feces to keep the “nest” clean. It is possible that dogs who aren’t cleaning up after their puppies may also engage in this cleaning behavior. Some researchers propose that eating feces may have had evolutionary benefits. Dogs are omnivores and dogs who scavenged and ate stools of carnivores may gotten some added nutrients with little energy expenditure. Since some intestinal parasites take a few days to reach an infective stage in the environment, eating fresh feces within a dog’s territory may be advantageous to help contain or prevent parasite transmission to members of the pack.
What Should You Do if Your Dog Eats Poo?
If your dog is suddenly eating its own or other dogs’ feces, it is best to consult with your veterinarian to ensure there isn’t a medical cause. A fecal parasite test may be recommended to screen for some intestinal parasites that may be a cause or consequence of your dog’s coprophagia. If any medical causes are identified, they should of course be treated. For the more common behavioral causes, the most effective treatment is behavior modification (training). The best way to prevent coprophagia is to pick up feces promptly and keep dogs on leash or well-supervised when in areas where other dogs’ feces might be present. Teaching dogs to come when called (and rewarded with an edible treat that is more high value than stool) and the commands “leave it” and “drop it” can also be helpful to prevent coprophagia. Food additives also exist that can be given to the “victim”--the dog whose stool is being eaten--with the idea that it will make the stool distasteful to the coprophagic dog. The problem with these additives is that they aren’t always practical, nor are they very effective. The additives have to be given to the dog whose stool is being eaten (and you can’t give medication to all of the dogs at the dog park!) and have to be given with every meal for a period of time (one product recommends giving it for 20 days). During this time period, the coprophagic dog is allowed to eat feces, which will ideally be unappetizing and stop the behavior. Unfortunately, a recent survey of owners of coprophagic dogs found the overall efficacy of these additives was 0-2% in eliminating coprophagia (Hart et al. 2018).

As a veterinarian, every day I see sick patients that have already been diagnosed by Dr. Google with a myriad of conditions. Some appear reasonable; others, however, are way out in left field. There was a time when I would dread the words “So I saw on the internet that Fluffy could have [Fill in the blank]”. My attitude has evolved, however, to where I now relish the opportunity to educate and have an open discussion about that particular patient’s condition. Moreover, as my clients have become better educated on various topics, I find the discourse between us more engaging and firmly believe this results in better care for my patients.
I think it is important, however, to keep some things in mind when searching the web for medical information. Here are some tips to keep in mind when searching the web for veterinary medical advice.
1. Ensure the advice is from a knowledgeable source. Articles written by licensed veterinarians are the ideal source. These are often supported by good science and are peer reviewed. Veterinarians are bound to uphold professional standards and rarely disparage other veterinarians or sources of information. Moreover, spreading of misinformation can put their license at risk.
2. Check multiple sources. Cross checking multiple quality sources will validate any information you may gather. This attenuates the risk of falling to a lone wolf that may be spreading false information or rumors.
3. Be aware of highly emotional articles or those that are derogatory of veterinarians or other professionals. I’m always quite suspicious of articles that will appeal solely to one’s emotional judgment or is derogatory of veterinary professionals. These articles are not based on sound science or professional standards, and often times end up trying to sell something. See below.
4. Be aware of sales pitches. I was once referred to a web site that was supposedly selling a “very high quality” food. The opening article was a diatribe on how veterinarians are in cahoots with food companies to sell diets that is killing our patients. But then it dovetailed into how much better their food was and you could buy it on their website. And remember, if it sounds too good to be true, it is.
5. Remember, there is no scrutiny of information available on the web. Articles aren’t screened for their accuracy and validity. It is up to us - as individuals - to validate information available to us. Utilizing a trusted, peer-reviewed source is important in having the most accurate up to date information.
6. Keep your veterinarian in the loop. No one knows your pet like you do. I would argue a close second is your veterinarian. Before you try something, talk to your veterinarian. There may be a particular issue or condition specific to your pet that may prohibit certain medications or treatment alternatives. Keeping the line of communication with your veterinarian open and fluid is paramount to maintaining your pet’s health.
Hopefully these tips help in keeping your pet healthy. I’ll reiterate it again, before you try anything you learned on the web, it is important you speak with your veterinarian. We both (you as the pet owner, me as the veterinarian) want to keep your pet as healthy and long lived as possible.
Say you went into the clinic for a physical exam and vaccinations and you were told your dog has a heart murmur. What does this mean? A heart murmur is an abnormal sound heard when listening to the heart beat. Instead of the normal “lub dub” sound, you will hear a “woosh dub”. The most common reason for this is a leaky heart valve (mitral valve or aortic valve) and the mitral valve which is on the left side of the heart is the most common type. There are other reasons for a murmur besides a leaky valve: anemia and thinner blood can create turbulence and a murmur; holes in the heart wall such as with young dogs with inherited heart defects; changes in heart shape and contractility from heart muscle diseases. Certain breeds have a higher risk of heart murmurs such as the Cavalier King Charles Spaniel, Toy and Miniature Poodle, Schnauzer, Shih Tzu, Cocker Spaniel, and other breeds under 25 pounds adult weight - these are usually due to changes in the valve leaflets due to breed genetics and age. (Large breeds with murmurs more often have heart muscle diseases and not valve changes, and starting a cardiac work-up is recommended and their diseases and risks will be covered in another article.). If your dog is otherwise healthy and there is no history of coughing or exercise intolerance, it is not likely the heart murmur is causing a problem yet, so we have some time to do a work-up. We would recommend chest x-rays to evaluate the heart size and shape and Vertebral Heart Score (VHS). This gives us a baseline to compare with x-rays in the future. The VHS helps us see if the heart is enlarging in response to the leaky valve, which lets us know it is time to start medications to help the heart contract better before heart failure starts. Many small breed dogs with heart murmurs develop congestive heart failure (CHF) over time, so yearly or twice a year exams and yearly x-rays are recommended. Some dogs need to have a cardiac ultrasound (echo) and EKG and blood pressure in addition to radiographs. Signs of CHF are coughing, breathing rate at rest >40 breaths per minute, gum or tongue color changes from pink (normal) to violet (abnormal), and exercise intolerance.
If your dog has been coughing and you brought him into the clinic and we found a heart murmur, we would recommend chest x-rays right away. Radiographs will show if there is fluid in the lungs (pulmonary edema) from congestive heart failure and we will measure VHS and look for heart enlargement. Some dogs with heart murmurs and a cough do not have congestive heart failure - they can have respiratory problems such as bronchitis, pneumonia, collapsing trachea, kennel cough, or cancer. Respiratory problems are treated differently than heart problems. There are good medications for dogs with CHF, including therapy with pimobendan, enalapril, and furosemide. An additional medication called spironolactone is added for some patients. With CHF, recheck x-rays and exams are needed to monitor response to treatment and blood tests are done to see if kidney function is being impacted by the medications. Staying in the hospital in an oxygen cage is necessary for patients with low oxygenation of the blood (pulse ox) along with fluid in the lungs (pulmonary edema). An exam by a board certified cardiologist and an echocardiogram is needed in some cases.
In summary, we recommend x-rays for all dogs with heart murmurs. With proper monitoring and medications, our canine friends can live longer, happier lives.
