Question: are wooly caterpillars poisonous to dogs?
Answer: Whilst Woolly Bear caterpillars look highly toxic due to their coloration, they aren't actually poisonous to dogs. ... It's not venomous but if your dog eats a Woolly Bear caterpillar, the hair can get stuck in their throat. This can lead to a possible allergy, but most likely coughing, gagging, and retching.
