My Dog Vomited Up a Worm
This isn't a scenario anyone enjoys, but it's more common than you might think. We even had a dog puke up a worm right here on the hospital floor during an exam.
That particular worm was long like spaghetti and white - an adult roundworm. Roundworms are an intestinal parasite that we commonly test for. This is the reason for the feces test that every pet needs at least once a year (or more frequently.) The test looks for eggs from the roundworm to indicate an intestinal infestation.
Dogs and cats become infected with roundworm upon ingestion of larvated eggs from a contaminated environment and ingestion of larvae in tissues of vertebrate hosts.
Treatment is simple. The doctors at Hometown Veterinary Hospital will prescribe a specific medication to eliminate the roundworms. If your pet is on a monthly heartworm preventative, like Sentinel for Dogs or Revolution for Cats, then they are getting dewormed monthly. This is the best practice in prevention.
This is a parasite that can harm humans. We encourage you to keep feces picked up, practice good hand-washing and keep all pets on monthly heartworm preventatives with a dewormer.
