Pica in Dogs: Welfare Causes and Management

Pica, the persistent eating of non-food items, is a welfare concern in dogs indicating either medical or behavioural problems that require investigation and targeted management.

Key Facts

Pica is defined as persistent consumption of non-nutritive non-food items
Common items consumed include fabric, rubber, stones, wood, and plastic
Medical causes include anaemia, gastrointestinal disease, and nutritional deficiency
Behavioural causes include anxiety, boredom, and compulsive disorders
Intestinal obstruction from pica can be fatal without emergency surgery
Some dogs develop pica related to early deprivation of appropriate chewing materials

Welfare Considerations

Pica causes welfare harm both as a symptom and a cause of further harm. The underlying condition whether medical or behavioural causes suffering. Intestinal obstruction from consumed items causes acute surgical emergencies. Compulsive pica indicates chronic anxiety that reduces quality of life. Investigation and treatment addresses the welfare of the whole animal rather than just managing the symptoms.

What You Can Do

Consult your vet immediately if your dog is persistently eating non-food items
Request bloodwork to rule out medical causes including anaemia and mineral deficiency
Seek a behaviourist referral if no medical cause is found
Manage the environment to prevent access to target items during investigation
Increase physical and mental enrichment to address boredom-related pica
Never leave a dog with pica unsupervised with access to dangerous items
