3. Excessive Drooling

Drooling is one of the most common features among dogs, even in general. But if your dog is drooling too much, especially after being administered Heartgard, please be cautious. This may indicate that the amount of Heartgard it has consumed is more than the prescribed quantity.

4. Seizures

One of the most severe symptoms of an overdose of Heartgard is violent fits or frequent episodes of seizures.

So, if you find your pet having seizures after consuming Heartgard, immediately contact your veterinarian.

Most veterinarians administer Heartgard to dogs at an early stage to ensure that the infection subsides as soon as possible.

Convenient Once-a-month Chewable Tablet

Heartgard should be given to dogs once a month, and it is best to provide it at a particular date in a month. As the tablets are chewable, people mistakenly give two doses to their dog.

How Much is Too Much Heartgard For Dogs?

Heartgard contains ivermectin and pyrantel. The minimum dosage of this salt combines 2.72 mcg/lb and 2.27mg/lb. Since this combination is strong, administering Heartgard is not favored if your puppy is less than six weeks old. Therefore, it should be administered according to the weight of your dog. Also, if you have a big dog weighing over 100 lb, there are chewable tablets of Heartgard in the market.

Ideally, if your dog weighs up to 25 lb, a 68 mcg of Ivermectin content and 57 mg of Pyrantel content should suffice. If your dog weighs anywhere between 26 lb to 50 lv, 136 mcg of Ivermectin content and 114 mg of Pyrantel content is required. For dogs weighing anywhere between 51 lb to 100 lb: the prescribed dosage of Ivermectin and Pyrantel content is 272 mcg and 227 mg, respectively.

Can I Give My Dog A Higher Dose Of Heartgard?

Dogs with heartworm disease need to be treated carefully. As a pet parent, you should know the proper dosage of Heartgard and what works for them the best.

Many dog owners suffer from this problem because they might need to be aware of the safety of a certain amount of Heartgard for their dogs. Therefore, it is best to inquire about the dosage of Heartgard that can be safely administered to dogs.

Heartworm is a parasitic that can be carried to dogs by the bite of an infected mosquito. One of the simple measures against heartworm illness is administering Heartgard.

Meanwhile, Heartgard is a drug that your veterinarian may advise you to give to your dog in order to assist in avoiding heartworm disease.

The solution largely relies on your dog’s size and body weight when you’re worried about administering a higher dose of Heartgard. Delivering the suggested quantity is generally preferable, rather than providing a lesser or greater dose.

Let us quickly look at the amount of Heartgard that can be given to dogs without posing any serious risk.

Recommendation Of Heart Gard For Different Dogs Of Different Sizes And Bodyweight

As previously noted, your dog’s size and body weight play a critical role in determining the appropriate Heartgard medication. 

Heart Gard pills are available in various sizes and can be given to big, medium, and small-sized dogs, depending on their weight. However, the quantity needs to be increased based on your dog’s size.

Is It Right To Give More Than The Recommended Amount?

You may not be entirely right when you believe that administering more Heartgard will enhance the likelihood that your pet won’t contract heartworm disease. First, administering a higher dose will not increase its effectiveness.

Moreover, it is equally important to question if Heartgard has any adverse effects on your dog’s health. Well, it does, similar to a variety of prescription medications.

If you choose to administer a higher quantity of Heartgard, let us tell you that a greater dose may result in even more difficulties than normal.

Depending on your dog’s weight fluctuations and how they respond to the medication, you might occasionally need to administer greater quantities. 

So it would be best to avoid administering a larger amount of Heartgard. However, there are some additional factors to be considered as well.

Besides, raise it continually based on how the dog responds to the recommended dosage of Heartgard. Because it is created exclusively for dogs, it takes a significant dose to have negative impacts.

Before providing Heartgard to a dog to cure heartworms, a veterinarian should indeed be consulted.

Can I Give My Dog A Lower Dose Of Heartgard?

Dogs are treated with Heartgard to combat heartworm infection. This is an oral drug that is used every month. Heartgard has the advantage of being simple to administer to dogs. Besides, it is considered successful at treating heartworm infections.

The medicine is prescribed at a measured rate for each dog, keeping its size and body weight in mind. Some canines, nevertheless, might be capable of withstanding a lesser amount.

Remember that Heartgard works against a parasitic worm that causes infection in a dog through the bite of a female mosquito that is infected. 

The medication depends entirely on the dog’s body weight and physique. If a dog’s weight is less, the amount of medication is less; if more, the quantity will be more.

Is It All Right To Give A Lower Dose Of Heart Gard?

Yes, Heartgard could be administered to certain dogs at a more minor concentration. But tampering with the prescribed amount of medicine is not at all recommended. 

Yet, some dogs may be able to withstand such changes in concentration while others will not be able to tolerate the same.

Moreover, consult your vet first if you are thinking of administering a lesser quantity of Heartgard. They will indeed be able to instruct you on the safety of the medication for your dog and the recommended dosage.

As you already know, the most effective way to prevent heartworms in your dog is with Heartgard. Nevertheless, dog owners remain hesitant to administer this medication to their dogs if they don’t fully comprehend it.

Given that it might have minimal adverse effects, they will most likely give a lower dose. At the same time, sometimes, some dog owners purchase smaller doses.

You should know that dogs are divided into three weight groups. The first one is small-sized, the second one is medium-sized, and the last one is large-sized.

Each group has a specific amount of medication. So, when you give your dog a smaller dose than advised, it’s not always the best course of action.

Furthermore, veterinarians say it’s critical to administer a precise amount of Heartgard based on your dog’s size. A lesser dose won’t benefit the dog at all; rather, this can also lessen the medication’s effectiveness.

In the end, it might not be able to eradicate the contamination of heartworm completely. This, in turn, jeopardizes the whole purpose of the medicine.

What Should I Do If I Can’t Remember If I Gave My Dog Heartworm Medicine?

First of all, relax! A medicine like Heartgard is meant to help your pet fight a deadly disease, and the way it works is by killing the worms attacking your pet. The treatment will take time to work, and if you can’t recall if you gave your dog the medicine, you can administer another dose just to be sure.

You can use a few tricks to ensure that you remember to give your pet the medicine next time.

Reminders

Mark your calendar based on the prescription. You can also set reminders on your phone to ensure that you do not miss the day or time when the medication is due.

Mix in Food

If your dog is acting up about taking medicine and is reluctant to follow instructions, you can mix the medicinal drugs in their food to ensure there is no trace of medicine.

Pill Case

Another efficient way is to maintain a pill case. The probability of forgetting to give your dog the required Heartgard dose is significantly reduced when you have a pill case. This is because you will have to open the case and take out the pill every time you need to give it to your dog.

Is It Dangerous If I Give My Dog A Heartworm Pill Early?

Puppies who contract heartworm infections may experience severe and long-lasting consequences. To begin, Heartworms cause abnormalities in the puppy’s cardiovascular system quite early. Your puppies’ cardiovascular system can be weakened even before anything can be noticed.

To make matters worse, vascular swelling in the cardiovascular system is brought on by heartworms. Moreover, the liver and cardiac muscle alone can do heavy damage. 

Unfortunately, when you delay appropriate treatment and the required medication until your puppy exhibits heartworm clinical signs, medication will be significantly difficult, risky, or perhaps hopeless.

By the time the heartworm contamination is discovered and properly treated, harm to the liver, heart muscle, kidneys, and vessels in the lungs may already be done. This implies that your puppy can experience a decreased survival rate due to their heartworm disease.

Can Heartgard Be Administered Early?

Heartworm illness is a terrible health condition and can be fatal for your dog, especially young puppies. It can even cause the death of your cherished pet. Therefore, prevention is crucial in this case! We recommend you not waste time on home remedies and take your pet to the doctor.

You are probably wondering now what will happen in case you have to leave on tour for work or another reason, thereby making it impossible for you to remain at home and administer your dog the medication on time. 

Do you want to skip administering Heartgard while you are away? Or is it acceptable to deliver it before the specified date?

Let us warn you immediately that one of the most hazardous aspects is delaying or skipping the heartworm medication, so take that into account. 

If such an event occurs, heartworm larvae will grow into adults and become adult heartworms, which is what these preventative medications will not be able to halt.

Now, if we come to the previously mentioned question, the answer can be given in two views.

In case of a mild condition

If you are wondering about the possibility of beginning to administer heartworm medication when the condition is still mild, the answer is YES. 

Heartworms survive and reproduce within adult canines, which serve as their hosts. Therefore, they have a negative impact on your dog’s health and can injure the heart, lungs, and vessels.

Therefore, it’s advisable to begin the therapy as promptly as possible. Doing so will result in your dog’s life being saved. However, remember that any medication on your dog must first be evaluated.

Administering the pill before the 30 days cycle

There are some pet owners who have already started administering heartworm treatment and are still determining if they can administer a pill sooner than the recommended 30-day period. In this case, the reply is, once more, a YES.

However, there is a crucial aspect that you need to keep in mind. The rotation of medications should now be restarted, albeit there is no danger in providing it early. This is because the new cycle you receive now corresponds to the new time each month to administer heartworm medication.

Your dog’s system typically retains heartworm medication for 24 to 48 hours. Within this time frame, young larvae will be killed. The medication will then be eliminated from the system.
