If you've caught your dog eating poop, you're not alone. This behavior, scientifically known as coprophagia, affects a significant number of dogs. Research from UC Davis School of Veterinary Medicine found that approximately one in six dogs are classified as "serious" poop eaters, consuming poop at least five times, while about one in four dogs have been observed eating poop at least once.
The Science Behind Dog Poop Eating
The research team at UC Davis suggest that poop-eating behavior may be a leftover trait from dogs' wolf ancestors. Their research indicates this behavior might have evolved as a way for canines to protect pack members from intestinal parasites that could be present in feces around their den areas.
Medical Causes to Rule Out First
Before assuming this behavior is purely behavioral, the American Kennel Club recommends consulting your veterinarian to rule out several medical conditions that could contribute to coprophagia:
Enzyme deficiencies
Nutrient absorption issues
Parasites
Thyroid conditions
Cushing's Disease
Diabetes
Environmental and Behavioral Triggers
Veterinary behaviorists have identified several non-medical factors that may contribute to coprophagia:
Stress and anxiety
Limited living space
Attention-seeking behavior
Confusion about food and elimination areas
The Nutritional Connection
Research has identified several nutritional factors that may contribute to coprophagia. Understanding these connections can help inform a comprehensive approach to addressing the behavior:
Vitamin B Deficiency
Studies have shown that B vitamins play a crucial role in canine digestive health. B vitamins are particularly important because:
They support proper enzyme function
Aid in nutrient absorption
Help maintain healthy appetite regulation
Support overall digestive system function
Enzyme Deficiencies
Dogs need specific digestive enzymes to properly break down and absorb nutrients from their food. When these enzyme systems aren't functioning optimally:
Food may pass through the digestive system without being fully broken down
Nutrients may not be properly absorbed
Dogs might instinctively seek additional sources of these enzymes
Stool from other animals might seem attractive as it contains partially digested nutrients
Dietary Balance Issues
A well-balanced diet includes the right proportions of:
Proteins
Fats
Carbohydrates
Vitamins
Minerals
When any of these elements are out of balance, dogs may develop unusual eating behaviors as their bodies try to correct the imbalance. Modern commercial dog foods can sometimes be higher in carbohydrates and lower in meat-based proteins than a dog's ancestral diet, which may contribute to nutritional seeking behaviors.
The Role of Gut Health
Emerging research suggests that gut microbiome health may play a significant role in digestive issues and eating behaviors. A healthy digestive system requires:
Proper probiotic balance
Adequate fiber intake
Strong gut barrier function
Efficient nutrient absorption
Practical Solutions
Environmental Management
Clean up waste immediately
Keep feeding areas separate from elimination areas
Supervise outdoor time
Use positive reinforcement training methods
Nutritional Support
Ensure a high-quality, balanced diet
Consider veterinarian-recommended supplements
Maintain proper hydration
Monitor food intake and digestion
Behavioral Modification
Practice "leave it" training
Use positive reinforcement techniques
Address any underlying anxiety issues
Provide sufficient mental stimulation
When to See Your Vet
Contact your veterinarian if:
The behavior starts suddenly
You notice other health changes
Basic interventions aren't working
Your dog shows signs of dietary issues
Prevention Tips
The most effective approach combines:
Regular veterinary check-ups
Proper nutrition
Environmental management
Consistent training
Stress reduction
Remember that while this behavior is concerning to us, it can be managed with the right combination of medical oversight, nutritional support, and behavioral modification. Start with a veterinary check-up to rule out medical issues, then work on a comprehensive plan that addresses both diet and behavior.
Consider adding a functional dog treat like Waggy Vites Daily Multivitamins to your pet's diet to address any vitamin and mineral deficiencies
