Pica, the compulsive consumption of non-food items, puts dogs at serious health risk and often signals underlying physical or psychological problems requiring attention.
Pica is a significant welfare concern from multiple angles. The underlying cause - whether medical or behavioral - often causes its own suffering. Gastrointestinal disease causes chronic discomfort; anxiety-driven pica reflects a dog's inability to cope with its environment. Foreign body ingestion can result in emergency surgery with significant pain and recovery time. Dogs with pica often live under heightened supervision and restriction, which can itself reduce quality of life if not managed carefully. Addressing root causes rather than merely preventing access to objects offers the best welfare outcome.
