Pica In Dogs: Complete Guide To Causes, Risks, And Treatment
Finding out what drives dogs to eat inedible things can reduce health hazards and stress.
Pica in Dogs: Causes, Risks, and Treatment Strategies
Pica is a complex behavioral and medical condition in dogs involving the compulsive ingestion of non-food objects. While many dogs occasionally chew or mouth foreign objects out of curiosity, pica is defined by a pattern of persistently eating items that are not considered food, including rocks, fabric, plastic, soil, and more.
What Is Pica in Dogs?
Pica is the habitual consumption of non-nutritive, non-food objects. These items vary and may include:
- Rocks, dirt, and sand
- Fabric (socks, towels, clothing)
- Paper and cardboard
- Plastic or rubber objects
- Wood, sticks, and mulch
- Toys and household items
Occasional chewing is normal in dogs, especially puppies, but compulsively swallowing inedible objects is abnormal and can pose significant health risks.
Symptoms of Pica in Dogs
The primary symptom is the repeated ingestion of one or more non-food substances. Owners may notice:
- Clues like missing socks, chewed up household items, or found objects in stools or vomit
- Digestive upset: vomiting, diarrhea, abdominal discomfort
- Lethargy and in severe cases, signs of intestinal blockage
Why Do Dogs Eat Non-Food Things? Exploring the Causes of Pica
Pica in dogs may result from a variety of medical and behavioral causes. Determining the underlying driver is essential for effective treatment.
Common Medical Causes
- Gastrointestinal disease: Disorders affecting digestion or absorption (inflammatory bowel disease, exocrine pancreatic insufficiency)
- Dietary deficiencies: Imbalances or deficits in nutrition, sometimes due to poor-quality food or absorption problems
- Endocrine disorders: Diabetes mellitus, thyroid disease (hypothyroidism)
- Anemia: Can drive abnormal appetites in some dogs
- Liver disease & pancreatic disorders: Cause metabolic or appetite changes
- Medication side effects: Steroids and certain drugs may increase appetite abnormally
- Parasitic infestations: Intestinal worms can disrupt nutrient absorption and appetite regulation
Common Behavioral Causes
- Anxiety and stress: Dogs under emotional duress, or experiencing separation anxiety, may resort to pica as a coping mechanism
- Boredom and lack of enrichment: Insufficient mental and physical stimulation can lead dogs to engage in destructive or compulsive behaviors
- Attention-seeking: Some dogs learn that eating forbidden objects gets a reaction from their owners
- Compulsive disorders: In some cases, pica is a compulsive behavioral disorder (similar to OCD in humans)
- Early life experiences: Puppies tend to explore the world with their mouths, but if this persists into adulthood, it can lead to pica
| Medical Causes | Behavioral Causes |
|---|---|
| Gastrointestinal disease, nutritional deficiency, anemia, endocrine or liver disease, medication, parasites | Anxiety, stress, boredom, lack of enrichment, attention-seeking, compulsive disorder |
Potential Health Risks: Why Is Pica Dangerous?
Though some objects pass through a dog’s gastrointestinal tract uneventfully, many do not. The main dangers associated with pica include:
- Intestinal obstruction: Large, rigid, or undigestible items can block the stomach or intestines, potentially requiring emergency surgery
- Internal injury: Sharp or rough items can perforate or damage the digestive tract, leading to peritonitis or sepsis
- Toxicity: Some ingested items may be poisonous, such as certain plants, chemicals, or batteries
- Choking hazard: Small, hard objects can block the upper airway
- Infection or parasite transmission: Eating feces or garbage can lead to gastrointestinal infections or expose the dog to parasites

How Veterinarians Diagnose Pica
Diagnosing pica involves identifying the frequency and pattern of abnormal eating, then determining any underlying medical or behavioral cause. The diagnostic process may include:
- Clinical history: Owners should provide details about the dog’s diet, environment, routines, and the nature, frequency, and duration of pica episodes
- Physical examination: Veterinarians check for signs of nutritional deficiencies, anemia, or illness
- Laboratory tests: Bloodwork and urine tests help assess organ function, screen for anemia, infection, and metabolic disorders
- Fecal testing: To check for intestinal parasites
- Imaging: X-rays or ultrasound to detect blockages, foreign objects, or gastrointestinal problems
If medical causes are ruled out, a behavioral consult or referral to a veterinary behaviorist may be recommended.
How Is Pica Treated in Dogs?
The best treatment plan depends on the root cause, whether medical or behavioral.
Treating Medical Causes of Pica
- Gastrointestinal or metabolic disease: Management with appropriate medication, diet changes, or supplements
- Deworming: Treating parasitic infections when present
- Nutritional support: Switching to a balanced, high-quality dog food; addressing specific deficiencies
- Medication adjustment: Modifying drug regimens that may be driving excessive appetite
Treating Behavioral Causes of Pica
- Increasing enrichment: Provide toys, puzzle feeders, and regular exercise
- Behavioral modification: Use positive reinforcement to encourage appropriate chewing and discourage inappropriate eating
- Reducing stress and anxiety: Establish consistent routines, provide a safe, quiet resting place, use calming aids if needed
- Management: Puppy-proof the home by removing tempting objects; supervise at-risk dogs
- Professional help: In severe or stubborn cases, consult with a certified veterinary behaviorist
In cases where medical and behavioral interventions are unsuccessful and pica causes ongoing risk, more stringent management, such as the use of basket muzzles during walks, may be required. Surgery may be needed to resolve obstructions or remove ingested objects that cannot pass naturally.
Prevention Tips: Managing and Preventing Pica
Not all cases of pica are preventable, but the following strategies can help reduce risk:
- Feed a high-quality, nutritionally balanced diet
- Ensure regular deworming and routine veterinary care
- Keep household objects, garbage, toxic substances, and potential choking hazards out of reach
- Provide plenty of toys and enrichment
- Engage your dog in daily exercise, interactive play, and training sessions
- Monitor close for signs of boredom or anxiety and seek help if necessary
Breed, Age, and Other Risk Factors
- Pica can affect any dog, but appears more frequently in young, highly curious breeds or dogs with a history of poor enrichment.
- Puppies often mouth objects, but true pica is less common in adults without an underlying cause.
- Dogs with histories of neglect, malnutrition, or traumatic experiences may be at higher risk.
Frequently Asked Questions (FAQs) About Pica in Dogs
Q: Can a puppy have pica, or is it only seen in adult dogs?
A: Pica can occur in puppies, but itâs more often a phase of oral exploration that they outgrow. If a puppy persistently ingests non-food objects despite redirection, consult a veterinarianâit may indicate medical or behavioral concerns.
Q: When is pica in dogs a medical emergency?
A: If your dog is vomiting, lethargic, straining to defecate, bloated, or showing abdominal pain after ingesting a foreign object, seek immediate veterinary attentionâthese are signs of possible intestinal obstruction.
Q: Are some foods or household objects more dangerous than others?
A: Yes, objects like batteries, sharp items, plastic bags, corn cobs, small balls, and toxic plants present the highest risk due to choking, toxicity, and injury.
Q: Can pica in dogs be cured permanently?
A: Many cases resolve with appropriate diagnosis and treatment, but some dogs with behavioral pica may require lifelong management and supervision.
Q: How can I tell if my dogâs pica is due to a behavioral or a medical issue?
A: Your veterinarian will evaluate your dog’s medical status first, then discuss behavior, environment, and recent stressors or changes at home to determine the likely cause.
