There are many different types of heartworm medication, ranging from chewable tablets to spot on treatments. Learn about the different options here.

When it comes to the prevention of heartworm disease, there are a lot of different options out there. Your vet can give you advice on choosing the best heartworm medication for dogs, but the choice also depends on your dog. If it’s hard for you to convince your pet to swallow a pill or chew a tablet, then a spot on treatment might be a better option. Also keep in mind that some medications are hard workers, warding off other parasites like fleas and ticks, as well as killing larval heartworms.

Generic or Brand Name?

Heartworm preventatives should be taken year-round. You may want to consider opting for a generic medication, which is cheaper than the brand name options. Generic pet medications have the same active ingredients as brand name medicines. Regardless of name, all heartworm medications use one of the following four ingredients: ivermectin, selamectin, moxidectin, or milbemycin oxime. Generic medications may not be available at the veterinarian's office, because they often do not have the space and finances to store a wide variety of medications.
