Why Dogs Eat Cat Poop: A Vet’s Complete Guide for 2025 🐶💩
By Dr. Duncan Houston BVSc
Introduction
Every pet parent knows the feeling: your dog trots over with that guilty grin… and you spot cat litter around their muzzle. If this sounds familiar, you’ve encountered coprophagia—and yes, Italy didn’t invent any new dessert called this. Let’s explore why this behavior happens in 2025, its possible health concerns, and proven strategies (including Ask A Vet tips!) to gently stop it. 🩺
1. What Is Coprophagia?
Coprophagia means “eating stool.” Although it may horrify us, it’s surprisingly common in dogs—and not always caused by illness.
- Normal instincts: Mother dogs clean their young by ingesting waste—puppies learn from them 📚.
- Scavenger instincts: Dogs are innate scavengers; cat poop may smell like a tasty treat because it contains undigested cat food.
- Behavioral habit: Once your dog starts, it often becomes self-rewarding and hard to break.
2. Key Reasons Dogs Choose Cat Poop
🍽️ Smells & Taste Like Cat Food
Cat diets are richer in protein and fats, making their outputs smell irresistible to a dog’s nose, like gourmet leftovers!
🏋️♂️ Boredom & Stress
Dogs left alone or under‑stimulated often seek things to sniff or chew—cat poop becomes an odd diversion. Anxiety or litterbox watching may worsen the behavior.
💡 Habit or Learned Behavior
Puppies often mimic others (including mom), and this behavior can stick, turning into a lifelong habit if not managed early.
🥗 Nutritional Deficiencies
Inadequately balanced or homemade diets may miss key nutrients or slow digestion—prompting pups to “supplement” from poop.
⚠️ Medical Triggers
Disorders like exocrine pancreatic insufficiency (EPI), malabsorption, Cushing’s, or diabetes can lead to ravenous hunger and coprophagia.
3. Health Risks from Cat Poop
- Bacterial infections: Salmonella, Campylobacter, and E. coli can be transmitted.
- Parasites: Tapeworm, Giardia, and Toxoplasma gondii can infect dogs and even humans.
- Litter hazards: Ingested clumping litter can cause intestinal blockages—potentially requiring surgery.
- Medication risks: Dogs eating medicated cat poop can absorb drugs like NSAIDs and risk liver damage.
4. How to Tell If It’s Medical or Behavioral
If your dog seems healthy otherwise but scouts the litter box, it’s likely behavioral. Persistent cases with weight loss, hunger despite eating, diarrhea, or unusual stool suggest a medical work-up:
- Full physical exam
- CBC/chemistry
- Fecal testing
- Enzyme levels (e.g. trypsin for EPI)
- If malabsorption is suspected, abdominal ultrasound, pancreatic function tests.
Always consult your vet—this article is for education, not treatment.
5. Solutions & Prevention
Here’s a full toolbox approach for preventing doggie litter‑snacking 🍀:
🐾 5.1 Manage Litter Box Access
- Clean frequently: scoop immediately after each use.
- Dog-proof your setup: use covered boxes, place them where only cats can reach, or behind baby gates.
- Invest in a self-cleaning box: devices like Litter‑Robot clear waste automatically, blocking temptation.
🧠 5.2 Behavior Training
- Teach strong commands: “Leave it,” “Come,” and “Off.” Practice around the litter box with high-value rewards.
- Use frequent short leash walks to intercept behavior mid‑action.
- Redirect with toys, puzzles, and enrichment sessions—keep minds and mouths busy!
💊 5.3 Dietary Tactics
- Choose a vet-approved, highly digestible diet that meets AAFCO standards.
- Discuss enzyme replacement (e.g., pancreatic supplements for EPI).
- Consider safe fecal deterrents (e.g., for-bid formulas)—but vet guidance is essential.
😌 5.4 Mental & Physical Enrichment
- Boost daily exercise: walks, playtime, fetch or swimming.
- Mental stimulation: food puzzles, scent games, training drills.
- Implement calming products if anxiety plays a role (e.g., Adaptil, pheromone collars).
🩺 5.5 Medical Treatment When Needed
- Treat underlying conditions (EPI, malabsorption, diabetes, Cushing’s).
- More severe behavior cases may require a referral to a veterinary behaviorist.
6. Monitoring & Timeline
With consistent management:
- Behavioral habits often break in 4–6 weeks with training and litterbox changes.
- If medical conditions are treated, expect 1–3 months for full recovery.
- Severe cases may need longer follow-up.
Keep a behavior log—time, environment, triggers. Discuss progress during visits to Ask A Vet or your clinic.
7. When to See the Vet Immediately
Seek veterinary care if you notice:
- Persistent poop-eating even after cleanup & training
- Weight loss, diarrhea, vomiting, excessive hunger
- Signs of GI blockage—abdominal pain, bloating, retching
- Behavioral changes or stress signs (lip‑licking, pacing)
The Ask A Vet app can connect you with a care team quickly—no waiting room required.
8. Case Example: Bella the Beagle
Bella, a 2‑year‑old Beagle, began raiding the litterbox after her owner started working longer hours. The vet exam ruled out illness. We identified boredom and cat poop’s appealing smell. A plan was established:
- Immediate litter scooping + gated litter box access
- New twice‑daily walks and Kong treats with kibble
- Training: “Leave it” practiced near the litter box
- Added digestive enzyme supplement
In 5 weeks, potty behavior was redirected—Bella no longer showed interest in the box 😊.
9. Summary Table
Top Cause | Signs | Solution |
---|---|---|
Boredom/Habit | The dog sneaks into the box | Clean box, train, enrich |
Dietary Deficit | Hunger, poor coat | A balanced diet, enzyme support |
Medical Issue | Weight loss, diarrhea | Vet exam, diagnostics |

Conclusion
While gross, their curiosity stems from instinct, boredom, or medical need. With vet-backed care, proper training, litterbox control, and enrichment, most dogs can break the habit. If problems persist, a vet or behaviorist can support you. Here’s to cleaner paws and happier families—2025 style! 🐕✨
