Parasite life cycles

Step through each cycle one stage at a time. The point of knowing the cycle is finding the place you can break it.

Endoparasites live inside the animal. Ectoparasites live on the outside. Worming and flea treatment are dosed by the animal's weight, so an animal is weighed before it's treated — guessing is how animals get underdosed or poisoned.

Background knowledge for learners. Choosing and giving treatments is work for a vet.
