If you can't make a regular schedule, taking oral tablets is the easiest way to administer. Regardless of what oral medication you use, underestimating the power of the good bribe is an omission. Some dogs have a tendency to refuse any kinds of medications so it's best to wrap your oral table in a ball of a very delicious food like cheese and other wet foods. This is a way which cheats your dog gulp the ball down without checking. Below are some of the oral medications for dog heartworm:

Heartgard Plus:

Because main ingredients include Pyrantel Pamoate and Ivermectin, aside from heartworm, it's also very ideal to prevent roundworm and hookworm. The dosage of Heartgard Plus is monthly.

This kind of medication is produced with a unique shape and flavor - beef-flavored chewable cube. If you are an owner of a dog which doesn't love medication, this is a great solution to cheating it. This is just considered as a reward for your dog.

In some areas wherein in the world, Heartgard Plus may be a product which comes with warnings staying away herding breeds such as shepherds, and collies due to its genetic sensitivity to ivermectin. Nonetheless, although this sensitivity relates to the deletion mutation of the mdr1 gene, it just happens with a pretty high dosage such as the use of mange treatment and stimulation of a reaction. No matter which breeds use, the too low dosage in Heartgard is safe and can't end up causing any reaction.


Apart from heartworm prevention, the main ingredient in Interceptor - Milbemycin oxime is one of the reasons to help hookworm, roundworm, and whipworm. The dosage of the Interceptor is monthly.

As a palatable medication product, Interceptor is chewable pills which are smaller than Heartgard Plus. According to feedbacks of previous buyers, their dogs love the flavor of this type of medication. In case your dog is a wise pet so you can't hide medication in its foods anymore, take interceptor as a try.


With the main ingredients including Pyrantel pamoate and Ivermectin, this is a great choice for heartworm, hookworm, roundworm, and whipworm. The dosage of Tri-heart is monthly.

As another generic form of Heartgard Plus, this is a cheaper option with the same ingredients. Thus, if the value of money is what you care about, Tri-heart is a wonderful product available on the market.


The main ingredients include Milbemycin Oxime and Spinosad. Its dosage is monthly. More than other products, Trifexis can prevent not only heartworm, hookworm, roundworm, whipworm but also fleas.

The uniqueness is that it is heartworm and fleas prevention that makes your care easier. However, this potent drug should make you cautious about allowing your dog to use. Apparently, Trifexis can kill the terrible parasites, but it is also the reason which causes an upset stomach.

Topical Liquids:

According to what previous buyers said, the liquid form of this heartworm prevention usually causes messy especially wigglers cause messier. Therefore, if you would like to get the use of topical liquids, I strongly recommend you do some research to know how to do properly before anything else.

Advantage Multi:

Imidacloprid and Moxidectin are 2 main ingredients of Advantage Multi. Like Trifexis, it can prevent heartworm, roundworm, whipworm, and fleas, the dosage is monthly.

Moreover, when it comes to price, this is not a completely wise choice. It's best to make a small investment first to be aware of how your dog reacts. If your dog ends up with a good result, a bigger purchase is right. Looking for some coupons and discounts may be helpful.


Selamectin is its main ingredient. What revolution can prevent is inclusive of ear mites, scabies, ticks, fleas, and heartworm, of course. Like others, the dosage is monthly.

If you own a cat, this is an ideal product which comes with many advantages. With dogs, to get the best outcome, the medication must be applied regularly without being missed. Thus, combining it with an oral medication (Heartgard or Interceptor) is a wise idea.


This is a good choice for owners who are on a busy lifestyle. If a monthly dosage can't be applied because of your schedule, make a purchase of injectable heartworm medication. ProHeart - the only injectable heartworm medication is available on the market so you can easily look for and buy it.


Moxidectin - its main ingredient is useful in heartworm and hookworm prevention. The dosage of ProHeart is 6 months.

Though this is very convenient, not all dogs can use. Keep your dog away ProHeart if it is old or allergic to one of the ingredients in ProHeart. You had better have an appointment with your vet to make sure your dog suits with this kind of medication.

Important note: Whether or not you intend to use Injectable, having an appointment with your vet is a must. He or she will let you know if your dog has heartworm and provide some advice about heartworm prevention.
