Roundworms in Dogs (Toxacara Canis)

Overview of Roundworms in Dogs

Toxacara Canis is a nematode parasite more commonly known as “roundworm” in dogs. It is found in almost every puppy at birth and affects mostly puppies and young dogs. It causes a “pot belly” appearance and can you can see adult worms shed in the feces that are long and slender most often described by clients as looking like spaghetti.

Toxacara Canis only affects dogs and other canids such as wolves and coyotes.

It is transferred through the contact and ingestion of contaminated feces, eating and infected host animal, and through the mammary glands of nursing animals. Most puppies are born with roundworm infections. Most pet stories and breeders will deworm puppies starting at 6 weeks and often every 2 weeks for 3 to 4 treatments.

Transmission to humans is possible through accidently touching infected feces and then touching the mouth or face or eating without washing hands. According to the CDC this is most important in children who play in or eat dirt, where roundworms can migrate to the eye and cause blindness and damage the retina. Encourage proper hand washing techniques in all individuals in contact with infected pets.
