My dog was near pine caterpillars. What are the signs and timing?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered

I just discovered that pine caterpillars are a danger to animals. We don’t go near pine trees often but last saturday we went to the park and last tuesday (2 days ago) my dad walked my dog close to pine trees. He’s acting normally, would sympstons have shown up by now in case he was affected? What are the signs?

It appears the most common signs are often related to dogs licking or eating the catepillar. Below is from a 2012 study:

"All dogs presented drooling, dysphagia (swallowing difficulty), submandibular lymphadenomegaly (swollen throat lymph nodes), and clinical signs of pain."

Symptoms started in some dogs in less then 2 hours. Rapid vet intervention was important within 2 hours as some dogs had injury/damage to the tongue itself, especially if vet care was not sought right away.

I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
