What Does Heartgard Protect Against? Heartgard and Heartgard Plus both protect dogs against heartworm infestation. Heartgard protects against heartworms alone. Heartgard Plus protects against heartworms, hookworms, roundworms, and other ascarids (types of intestinal parasites).

Heartgard Plus treats and controls 3 species of hookworms and 2 species of roundworms. It kills heartworms in the larvae stage and prevents possible serious damage to your dog. Heartgard Plus is well tolerated. All dogs should be tested for heartworm infection before starting a preventive program.

Heartworm disease has been diagnosed in all 50 states. And just one bite from an infected mosquito can transmit this potentially deadly disease to your dog. The risk is real. That's why vets recommend using monthly heartworm disease prevention all year long.

The active ingredients in Heartgard PLUS are Ivermectin and Pyrantel Pamoate. Ivermectin and Pyrantel Pamoate control and kill certain parasites like heartworms, hookworrms, and roundworms.

It contains 2 medications: ivermectin and pyrantel pamoate. Ivermectin prevents heartworm disease by killing heartworm larvae that have infected your dog during the previous 30 days. By killing the larvae, HEARTGARD Plus stops larvae from developing into juvenile and adult heartworms, thereby preventing the disease.

Heartworm treatment is expensive due to several factors: Heartworm medications are relatively new, and their high price is attributed to research and development costs. Moreover, the medication is often imported, making it more expensive to obtain.

The monthly heartworm preventative we prescribe only lasts in a dog's or cat's body for one to two days, not 30 days, due to the lifestyle of the heartworm, it is only necessary for the pet to take the heartworm preventative every 30 days.

Although there are fewer mosquitoes in the winter, there is still a risk that your pet could get heartworms if you stop giving heartworm prevention medication during this season. That's one reason veterinarians strongly recommend pets receive heartworm prevention medication year-round.
