Whip worm Life cycle in dogs

Pet parents can prevent and treat their pooch from intestinal parasites like whipworms by learning about the whipworm’s life cycle.
While not exactly pleasant to think about, understanding a parasite’s life cycle helps us break up the life cycle to treat infestations better and allows us to choose the appropriate preventatives.
There are three stages of the whip-worm life cycle:
- Egg
- Larvae
- Adult
Adult whip-worms lay their eggs in the large intestine, where they are then passed into the dog’s stool to infect the environment.
The eggs mature to an infective state, or embryonated, in the environment, and are ready to re-infect the host or infect a new host in 10-to-60 days.
Once ingested, they hatch and mature in the lower intestinal tract, where they attach to feed and lay more eggs, continuing the cycle.
