Interceptor Plus Vs Heartgard Plus: The Ultimate Review

Interceptor Plus Vs. Heartgard Plus: The Ultimate Review

Dogs are some of the most loyal and friendliest animals in the world and the most desired pets in families. They are perfect role models of friendship because they don’t just follow you like friends, but they also neither complain nor demand anything. Although some dogs can be moody, that’s how they have been raised. Sometimes these beautiful creatures can be in pain and won’t show until you notice it. Therefore, you need to take precautions and make sure you are giving them the care they need.

Some of the biggest threats to dogs are worms and other health issues they can cause. A dog’s life-expectancy is small compared to ours, so let us make sure it is filled with joy and good health. Now there are many products you can choose from for your dog’s care, but Interceptor Plus and Heartgard Plus are considered the best of all. However, you may be wondering which one is better than the other and right for your dog. In that case, this article is perfect for you, so without further ado, let’s get into it.

Heartgard Plus

As the name suggests, Heartgard Plus is the ultimate protection against heartworms, which are deadly for your dog. Heartworms are not a regional threat because they are passed on when a mosquito bites the dog and leaves the heartworm larvae inside the dog. The larvae begin to grow and start affecting different parts of the dog’s body, ultimately reaching the heart and becoming lethal.

The Heartgard Plus is right for all dogs that are above six weeks. The chewable tablets contain ivermectin/pyrantel, which fights against the heartworms and protects against hookworms and roundworms. According to the brand, they assure that the tablet doesn’t just kill the problem but also controls its spread and future risks, which is why you can feed your dog Heartgard Plus once every month and have a whole year of assurance.

How Does It Work – How Often Should You Feed It?

Heartgard Plus’s components are especially effective against heartworm, hookworm, and roundworm and guarantee your dog full safety as long as you feed it on time. The brand offers different packaged doses depending on your dog’s weight, which you need to provide once every month.

Every veterinarian prefers Heartgard Plus when the dog is unprotected against heartworms. However, will your dog eat it without any issues? Yes, it will, because the chewable is made with beef-flavor, which makes the dog eat it without a problem.



  • Since it’s a delicious oral treatment, it’s really easy to feed the dog; in fact, your dog may find it to be its favorite treat. However, make sure you don’t provide more than advised.
  • If you are an owner of more than one dog, then this treatment doesn’t require you to keep them separated, unlike many others. You can feed them both at the same time and have them enjoy time together.
  • Unlike Heartgard, the Plus version shows effectiveness against hookworms and roundworms also.
  • The dose is once a month, which is low compared to other treatments, making this cost-friendly.
Not So Good


  • One of the components is Ivermectin, which can be allergic to some dog breeds; therefore, always ask your vet if your dog is compatible. If your vet says so, then there shouldn’t be anything to worry about.
  • You need to make sure that your dog chews the tablet and not swallows it directly. If the dog doesn’t want to chew, then crush the tablet and sprinkle it over the food.

Interceptor Plus

The competitor Interceptor Plus comes with a unique, powerful punch. Unlike Heartgard, it contains two components: super-effective against most of the worms that your dog needs protection from. The milbemycin works great against heartworms, hookworms, and roundworms, the same as Heartgard Plus. However, the presence of praziquantel makes it effective against four different species of tapeworms and even whipworms. Both of the components have been trusted by the vets for over a few decades, which shows that they aren’t in the testing phase but are far more effective than you think.

How Does It Work – How Often Should You Feed It?

First of all, you need to consult with your veterinarian regarding this, because they know your dog’s health the best. Many people often forget that Interceptor Plus is used when your dog is tested with heartworms, unlike other worm prevention treatments. The treatment makes sure that your affected dog comes out safe and healthy and continues to live well.

Just like Heartgard, you need to feed your dog once a month and make sure that no doses are missed, and the dosing interval is not messed up. If you somehow miss a dose, contact your vet immediately and ask for further guidance.



  • If you think Heartgard is better at killing heartworms in comparison to the Interceptor, then you may be wrong; both are just as effective, which is why the Interceptor is so great for dogs.
  • Unlike Heartgard, Interceptor Plus works great against five types of worms and many species of all these worms. So, giving your dog a monthly dose is a definite assurance that your dog is 100% protected.
  • Both active-ingredients of the treatment are safe and guaranteed to work for many years.
Not So Good


  • Interceptor Plus comes with some side effects; however, if your vet has prescribed this to you, then you are most likely not going to be affected by them.
  • Depression, vomiting, and diarrhea are some of the side effects that are caused by Interceptor Plus.
  • Just like Heartgard Plus, you may want to be careful because some breeds can be allergic to a component found in Interceptor Plus.


Here was all about Interceptor Plus vs Heartgard Plus. It’s safe to say that Interceptor works better than Heartgard in terms of effectiveness, but it depends on what your veterinarian prescribes you. Because they know your dog’s health better than anyone, they are the only ones who can know which one is more beneficial for your dog. Therefore, keep your dogs safe and ensure you feed them properly, and protect them against all worms.

Happy Petting!
