“I found this worm on the hardwood floor”, writes Kelly in her submission regarding the long, thin worm-like creature pictured below. “We have a small Maltese so we were freaking out as it might be a simple earthworm or a parasite that came out of my dog! I checked my dog’s stool but didn’t see any signs of worms. The length was about 4+ inches. Thank you so much for your help!” Firstly, we want to thank Kelly ourselves for the photo and ample context. These factors always help us identify the worms we are asked about. And with that said, we think Kelly found a centipede.
