Dogs can become infected with Toxocara canis by ingesting feces or soil which is contaminated with larvae. If the dog eats an infected animal (rat, mice, birds) he may contract the roundworm. Cockroaches and earthworms may also carry roundworm larvae, which can be transmitted to the dog if they are ingested.
