Identifying larvae that may be found in the feces of dogs and cats offers a diagnostic problem to the veterinarian. Some larvae may be from free-living nematodes instead of those from parasites, and some "larvae" may actually be plant structures. The purpose of this article is to discuss the recognition and identification of nematode larvae found in fecal specimens from dogs and cats.
