Pica in Dogs
What Is Pica in Dogs?
Pica is a condition where dogs compulsively eat non-food items. Unlike normal chewing, pica involves the actual ingestion of these items. Common objects consumed include metal, plastic, cloth, garbage, rocks, paper, dirt, and feces. Particularly attractive to dogs are items carrying their owner's scent, such as underwear, socks, and towels.
Pica is often seen as a psychological or obsessive-compulsive behavior but can also stem from medical issues or poor nutrition. Ingesting non-food items can be extremely dangerous, leading to toxicity, choking, stomach upset, or life-threatening gastrointestinal blockages. Immediate veterinary attention is crucial if ingestion is suspected.
Symptoms of Pica in Dogs
Detecting pica involves observing your dog's behavior and noting any ingestion of non-food items. Symptoms that may indicate pica include:
Vomiting
Diarrhea
Bad breath
Broken teeth
Decreased appetite
Pawing at the mouth
Gagging or retching
Abdominal bloating
Straining during bowel movements
Little to no feces produced
Dark, tarry stool
Excessive drooling
Coughing
Discoloration of mucous membranes
Visible distress or abnormal behavior
Causes of Pica in Dogs
Pica can result from medical conditions, parasites, or nutritional deficiencies. More commonly, it is due to mental health issues like boredom, depression, anxiety, or extreme hunger. The most prevalent form of pica is coprophagia, the ingestion of feces, which is sometimes seen in nursing female dogs and young puppies but typically diminishes with age. Dogs with separation anxiety often chew and ingest items when left alone.
Certain breeds, such as Labradors, are naturally more prone to pica. High-energy dogs without sufficient exercise or stimulation may also develop this behavior. Pica can also be an attention-seeking behavior due to lack of socialization. Medications like prednisone or phenobarbital, which increase appetite, can contribute to pica.
Medical conditions associated with pica include:
Immune-mediated hemolytic anemia (IMHA)
Iron deficiency anemia
Inflammatory bowel disease (IBD)
Liver or pancreatic disease
Hookworm infection
Gastrointestinal cancers
Diabetes mellitus
Hyperthyroidism
Malnutrition or unbalanced diet
Diagnosing Pica in Dogs
Veterinarians will perform a comprehensive physical examination and recommend lab tests such as a complete blood count (CBC), serum chemistry profile, fecal check, and urinalysis. These tests help diagnose underlying medical conditions. If IBD or pancreatic conditions are suspected, additional blood tests and an abdominal ultrasound may be necessary. X-rays can detect ingested non-food items and determine if an obstruction is present.
Behavioral causes are considered after ruling out medical conditions. Identifying the exact cause can be challenging and may require collaboration between the pet parent and veterinarian.
Treatment of Pica in Dogs
Treating pica depends on its underlying cause. Medical conditions must be addressed thoroughly. If an intestinal blockage occurs, surgery and hospitalization are required. Immediate veterinary intervention is necessary if choking is suspected.
For behavioral causes, referral to a veterinary behaviorist or therapist is often recommended. These professionals can implement intensive behavior modification techniques or prescribe medications for mental health conditions. Behavior modification may involve reducing anxiety and redirecting the dog's chewing behavior with safe alternatives.
Increasing physical exercise and mental stimulation can help manage pica. Regular walks, playtime, and puzzle toys can keep a dog's mind and body engaged. Keeping household items like socks and underwear out of reach is essential. In severe cases, a basket muzzle may be necessary when the dog is alone or outside.
Real-World Example: Buddy's Battle with Pica
Buddy, a 3-year-old Labrador Retriever, developed pica after his owner started working longer hours. He began ingesting socks and other clothing items. Buddy's veterinarian conducted a thorough examination, ruling out medical conditions. It was determined that his pica was due to separation anxiety. A behaviorist recommended increasing Buddy's exercise, providing puzzle toys, and using a basket muzzle when unsupervised. Over time, with consistent training and increased mental stimulation, Buddy's pica behavior decreased significantly.
Natural Remedies for Pica in Dogs
Natural remedies can aid in managing pica. For anxiety, an Adaptil® pheromone diffuser or calming collar, along with VetriScience® Composure supplements, can be beneficial. Probiotics can promote gut health, potentially helping dogs with intestinal conditions linked to pica. Supplements that make stool unpalatable can reduce coprophagia.
Recovery and Management of Pica in Dogs
Pica is often a lifelong condition that requires ongoing management. Crate training can prevent dogs from accessing non-food items when unsupervised. Regular mental and physical stimulation is vital. Toys that can be stuffed with food provide an appropriate outlet for chewing behaviors. It is essential to supervise dogs to prevent them from swallowing toy pieces.
The best prevention strategy is to remove access to non-food items while addressing the underlying condition. With patience, consistency, and professional guidance, managing pica in dogs can improve their quality of life and prevent potentially dangerous situations.
