Types of intestinal parasites in dogs
The Ascaris

The Tenia (to flat)
The tenia is the most common flatworm In the dog. It can measure up to 80 cm, but it is generally observed only rings (like rice grains) on the stools or around the anus of infested dogs.
Typical symptoms : The presence of these segments in the very sensitive anal area often causes dogs to rub their rear-train on the grounda typical parasitic infestation behaviour.
It is particularly difficult to eliminate this parasite as dogs regularly reinfest themselves by ingesting contaminated chips by tenia larvae. This is why our antiparasitic services systematically recommends that vermifugation be supplemented with effective treatment against fleas.
