Heartworm in Dogs – Common FAQs

Why heartworm preventative treatment is necessary?

Heartworms reside in the infected animal’s heart and lungs. With time, these parasites block surrounding blood vessels. Interrupted blood supply results in lung (organ) damage, cardiac disease, and death in the end. However, heartworm preventatives kill heartworm larvae and thus prevent a major infestation. This is why veterinarians treat mild heartworm infestations with a heartworm preventative during a period of a few months.

How do dogs get heartworm disease?

Heartworm infection is transmitted through mosquito bites. When an infected mosquito bites a dog, the heartworm larvae enter the dog’s bloodstream. Overtime, these heartworm larvae migrate to vital organs like the heart and blood vessels, where they mature into adults and reproduce microfilariae during the course of 6 to 8 months time.

Users Experience:

Many users of Heartgard Plus and Interceptor have confirmed that the taste and flavor of these tablets were enough to induce dogs to take them without hassles. Pet parents did not require making much of an effort in the administration process, especially for Heartgard Plus, due to its chewy feel.

Some dog owners expressed their dissatisfaction with Heartgard Plus, as it couldn’t protect their animals against whipworm infections. However, both Interceptor Spectrum and Heartgard Plus were found to be sharing equal tolerance levels in user dogs.



After going through this comparison, you will be able to choose the right product in accordance with your dog’s requirements. If your aim is to protect your dog against only heartworms, either of these options will work. But if you want to safeguard your fur babies against intestinal worms like roundworms and hookworms along with heartworms, Heartgard Plus is a good choice between the two. What is more, if you want additional protection such as tapeworms and whipworms along with heartworms, roundworms, and hookworms, go for Interceptor Spectrum.
