Dogs are known for their quirky and sometimes puzzling behaviours, but few habits baffle pet owners more than eating cat poop. If you’ve been wondering why dogs eat cat poop, the reasons range from deep-rooted instinct to nutritional gaps. This behaviour, known as coprophagia, is relatively common — and in this guide, we’ll explore what drives it, the potential risks, and how to stop it.
Why Do Dogs Eat Cat Poop?
Dogs eat cat poop for several reasons, ranging from instinctual habits to nutritional deficiencies. Understanding these causes can help you address the issue effectively.
Instinctual Behaviour
Dogs are natural scavengers. Their ancestors survived by eating whatever they could find, including faeces. This survival instinct still exists in modern dogs, making them curious about anything that smells interesting — including cat poop.
Nutritional Deficiencies
A dog may eat cat poop if its diet is lacking certain nutrients. Cat faeces often contain undigested proteins and fats that attract dogs, especially when their own food is missing these essential nutrients.
Taste and Smell
Cat poop often smells enticing to dogs because of the high-protein diet of cats. The scent and taste of cat faeces can strongly appeal to a dog’s keen sense of smell.
Boredom or Anxiety
Dogs may engage in coprophagia out of boredom or stress. If your dog isn’t getting enough physical or mental stimulation, it might start eating cat poop to pass the time or relieve anxiety.
Learned Behaviour
Sometimes dogs observe other animals eating faeces and copy the behaviour. Puppies, in particular, are more likely to experiment and learn from their environment.
Is It Harmful for Dogs to Eat Cat Poop?
While eating cat poop may seem harmless at first glance, it can pose real health risks for your dog.
Parasites
Cat faeces can contain parasites such as roundworms, hookworms, or the organism that causes toxoplasmosis, which can be transmitted to your dog. These parasites can cause anything from digestive problems to serious illness.
Bacterial Infections
Dogs that consume cat poop risk exposure to harmful bacteria, including salmonella and E. coli. These bacteria can lead to gastrointestinal distress or more severe infections.
Intestinal Blockages
If your dog ingests cat litter along with the faeces, it can block their digestive system. Clumping litter, in particular, can expand inside your dog’s intestines and cause serious complications.
Toxicity from Medications
If the cat has been medicated, its faeces may contain traces of drugs that could be toxic to your dog — especially antiparasitics or other potent medications.
How to Prevent Your Dog from Eating Cat Poop
Fortunately, there are several proven strategies to stop your dog from indulging in this undesirable habit.
Clean the Litter Box Regularly
Keeping the litter box clean is one of the easiest ways to remove temptation. Scoop the litter box at least once or twice a day.
Use Dog-Proof Litter Boxes
Consider investing in a dog-proof litter box. These designs make it difficult for your dog to reach the contents while still allowing your cat easy entry.
Adjust Your Dog’s Diet
If nutritional deficiencies are suspected, consult your veterinarian to ensure your dog is getting a balanced diet. Adding supplements or switching to a higher-quality dog food may help.
Provide Mental and Physical Stimulation
A bored dog is more likely to engage in undesirable behaviours. Make sure your dog gets plenty of exercise and mental enrichment through activities like puzzle toys, training, and playtime.
Train the Leave It Command
Teaching your dog the “leave it” command can be highly effective. With consistent training, you can discourage your dog from approaching or eating cat poop.
Limit Access to the Litter Box
Place the litter box somewhere accessible to your cat but out of your dog’s reach. Baby gates or cat doors can help create barriers.
Understanding Your Dog’s Perspective
To address the issue effectively, it helps to understand how your dog perceives the world.
Dogs Explore with Their Mouths
Dogs use their mouths to investigate their environment. While it seems unpleasant to us, eating cat poop is just another way for them to learn about their surroundings.
Smells Are Appealing
What smells repulsive to humans can be fascinating to dogs. Cat faeces have a strong odour that dogs find intriguing.
Pack Mentality
In the wild, mother dogs clean up after their puppies by consuming their waste. This behaviour can carry over into domestic dogs, especially if they see themselves as part of a pack.
When to See a Veterinarian About Your Dog’s Coprophagia
While occasional coprophagia in dogs can be relatively common, persistent or severe cases deserve more attention. If your dog frequently eats cat poop, it may signal an underlying health or behavioural issue. If you notice any of the following red flags, consult your veterinarian for a professional diagnosis.
Digestive Upset: Vomiting, Diarrhoea, or Constipation
If your dog shows signs of digestive upset after eating cat poop — such as vomiting, diarrhoea, or constipation — something isn’t right. Ingesting faeces can introduce harmful bacteria, parasites, or toxins, and swallowed cat litter may cause blockages or irritation in your dog’s intestines.
What to Watch For:
- Vomiting or retching after eating cat faeces
- Diarrhoea that continues for more than a day
- Difficulty defecating or signs of constipation
- Excessive drooling or signs of discomfort after eating cat poop
If any of these symptoms persist, they could indicate a gastrointestinal infection, an intestinal blockage, or even poisoning. Prompt veterinary care will help prevent further complications.
Weight Loss: Unexplained Weight Loss Could Indicate Health Issues
Unexplained weight loss in dogs is always a cause for concern. If your dog has been regularly eating cat poop, it might not just be a behavioural issue — consuming faeces can indicate poor nutrition or an unbalanced diet, leading to malnutrition and weight loss.
What to Watch For:
- Noticeable or sudden weight loss
- A decrease in muscle mass or visible ribs
- Lack of appetite or reduced interest in food
- Unhealthy coat or dry, brittle fur
If your dog shows weight loss alongside coprophagia, take them to the vet for a full nutritional evaluation. There may be a deficiency in their diet or an underlying condition affecting their ability to absorb nutrients.
Lethargy: Reduced Energy Levels May Signal Infection or Nutritional Deficiency
If your dog seems unusually lethargic or uninterested in activities it normally enjoys, it could be a sign of a more serious issue. Low energy may indicate a bacterial or parasitic infection from eating contaminated cat poop, or a nutritional deficiency making your dog weak and fatigued.
What to Watch For:
- Lack of interest in walks, play, or other favourite activities
- Sleeping more than usual or excessive resting
- Slow movement or reluctance to get up
- Not responding to stimuli or commands
Lethargy paired with coprophagia could mean your dog has ingested something harmful or isn’t getting adequate nutrition. It’s essential to see a vet who can run tests for parasites, infections, or nutrient deficiencies.
Persistent Parasites: Recurring Parasitic Infections Linked to Coprophagia
One of the most serious risks of dogs eating cat poop is exposure to parasites. Cats can carry roundworms, hookworms, and the organism that causes toxoplasmosis, which can be transmitted to dogs through faecal ingestion. Recurring infections may suggest the behaviour is increasing your dog’s risk of reinfection.
What to Watch For:
- Repeated worm infestations (roundworms, hookworms, etc.)
- Symptoms like bloated abdomen, coughing, or lethargy
- Blood in stool or changes in bowel movements
- Vomiting and loss of appetite
If your dog is experiencing frequent parasitic infections despite being on a deworming regimen, your veterinarian will likely perform faecal tests and recommend a more targeted treatment plan.
What to Do If You Spot These Red Flags
If your dog exhibits any of the red flags listed above, schedule a veterinary appointment promptly. Your veterinarian will conduct a thorough examination, which may include:
- Physical examination to check for signs of infection or distress
- Faecal analysis to test for parasites or bacterial infections
- Blood tests to evaluate overall health, nutritional deficiencies, or organ function
- X-rays or ultrasounds if there is a concern about internal blockages or damage
Once a diagnosis is made, your vet will discuss the best course of treatment — this may involve dietary changes, prescription medication for infections or parasites, or specific interventions to correct behavioural issues.
