Trifexis is indicated to treat and control intestinal parasite infections of adult hookworms, roundworms and whipworms in dogs. In occasional cases, it is possible that you might see intestinal worms being expelled in your dog's stool, this means Trifexis is working. If you have questions, consult your veterinarian for measures you can take to prevent a reinfection of intestinal parasites.
Hookworm (A. caninum), roundworm (T. canis, T. leonina), whipworm (T. vulpis) and tapeworm (T. pisiformis, E. multilocularis, E. granulosus and D. caninum)
