Preventing parasites vs. treating parasites in dogs

May 2, 2017 Category: Parasite education


When it comes to protecting your dog from parasites, there’s a big difference between preventing parasites and treating parasites in dogs. Here’s a quick breakdown and how that applies to Trifexis® (spinosad + milbemycin oxime).

Preventing canine parasites
Preventing parasites means proactively protecting your dog from getting these nasty little creatures so it never happens.

Treating canine parasites
Treating or getting rid of parasites refers to the process of killing or removing existing parasites from your dog.

Does Trifexis prevent or treat parasites?
Well, it depends on the parasite. Trifexis kills existing fleas and prevents any future flea infestations, so it offers both prevention and treatment for fleas.

When it comes to protecting your dog from heartworm disease, prevention is the best medicine. That’s why the American Heartworm Society recommends year-round administration of medication like Trifexis that prevents your dog from getting heartworm disease.1 Trifexis does not treat existing heartworm infections, so your veterinarian should test your dog before starting Trifexis.

Trifexis also treats and controls existing adult hookworm*, roundworm and whipworm infections. It does not prevent these parasites from infiltrating your dog’s body, but regularly using Trifexis will quickly treat any resulting infections from these creatures. It’s also important to know that dogs need to be 8 weeks of age or older and weigh 5 pounds or more to use Trifexis.
