Thaumetopoea pityocampa, commonly known as the pine processionary caterpillar, is a lepidopteran larva cloaked in irritating setae. These hairs carry a potent protein that can trigger severe reactions in dogs, including skin irritation, eye damage, and respiratory distress. The threat persists even after the insect becomes a moth, so prevention remains essential.
