Side Effects of Heartgard in Dogs

side effects of heartgard

The old saying that prevention is better than a cure is never more right or more important than your pet and worm treatments. Roundworms, hookworms, and heartworms move easily through mosquitoes or feces and therefore usually affect our pets. If left untreated, insects can spread and grow, causing serious complications in your pet’s intestines and respiratory system. Worm infection can cause severe digestive problems, heart failure, and even the death of your pet.

Insects can also be transferred to humans, so you must have an effective worming care plan. Infection protection needs to be done regularly. Fortunately Heartguard Plus is a monthly, easy administration, very safe, and proven treatment for worm control. This prevents insects from developing into a dangerous adult stage and is available for cats, both for dogs.

It is highly likely that every puppy or dog is exposed to insects. Puppies need to worsen every two weeks until women aged 12 weeks and lactating should be treated. Dogs older than 12 weeks require frequent treatment for the rest of their lives.

Heartguard Plus is available in different doses for different weight animals. It comes as a delicious and deliciously delicious tablet (or so I have seen). The dosage is designed to be chewed instead of swallowed whole so that you can always break it down and include it in your pet’s food. You will need to make sure that your pet consumes the full dose, so observe them during administration and after a short time.

You must talk to your vet before starting any treatment for heartworm. Not only to verify the correct dose, but also severe reactions similar to toxic shock can occur, in animals that already have heartworm infection and are then given the drug heartworm. Your dog should be tested before beginning any course of worm control, and if infected, adult heartworms and larvae (microfilaria) are treated.

If you are currently enjoying a good meal, it is best to keep your food aside as we take a closer look at these sinister, villainous little insects.


Roundworms (ascarids) are the most common insects affecting dogs and cats. Virtually every puppy is infected with roundworm at birth or becomes infected with its mother’s milk.

Adult worms are found in the intestine and can be 2-3 mm wide and up to 20 cm long. Roundworms cause diarrhea and vomiting, weight loss, poor growth, pot-bellied appearance, and lethargy. If left untreated or in severe cases, there may be pneumonia and obstruction of the intestine or digestive system.

In infected animals, adult worms lay eggs which are then expelled into the feces. Other animals become infected by entering contaminated soil or eating other infected animals such as rats, rodents, or birds. The eggs then enter the stomach of the animal, feed on the material found here, and develop into adults that lay eggs. Roundworm larvae and adults can also be found in other organs such as the liver and lungs but usually reside in the digestive system.


Hookworms are another intestinal parasite that commonly affects young dogs and cats. Insects feed on the intestinal lining of the host animal and blood, tissue, and fluid. With roundworms, larvae and adult egg-laying insects live in the gut. Some worms attach to other organs and this can be particularly problematic for your pet if they migrate through the respiratory system.

Hookworm eggs are expelled into animal feces. Dogs and cats can be infected with contaminated soil or by skin-penetrating larvae. Puppies can also become infected through their mother’s milk.

Bloody diarrhea is a common symptom of hookworm. Other signs of infection are intestinal disturbances, pale gums, weight loss, growth, and poor coat condition. A large number of insects or puppies may cause severe loss of blood and anemia. In extreme cases, it can cause death.


Heartworm is the deadliest of all parasites, and although dogs are more susceptible to infection, cats are also at risk. Insects live in the lungs, heart, and pulmonary arteries of animals and can cause heart failure or death. Puppies should start the prevention of heartworm by at least 12 weeks of age.

Primarily it is the lungs that are affected by heartworm but the heart, circulatory system, and even liver and kidneys can be damaged. Symptoms that indicate a heartworm infection include shortness of breath, breathlessness, cough, laziness, fainting, blood present in saliva or mucus, weight loss, abdominal bloating, loss of appetite, and vomiting.

Heartworms are transmitted by mosquitoes and when an infected mosquito bites another animal, heartworm larvae (microfilaria) migrate. These reach the lung, heart, and pulmonary arteries via the larval tissue and the circulatory system of the host animal, feed into the blood and grow to maturity, with some insects reaching 30 cm in length and 2 cm in width. Heartworm larvae can live up to two years in the bloodstream of a host animal.

The germs of the heart will cause inflammation of the tissue, blood clots, and thickening of the blood vessel walls this may cause the blood pressure of the animal to increase, and the cardiac strain increases.

Extreme side effects occur if a dog is treated with a prevention medication and is already infected with heartworm.

Side effects of Heartgard

As with any medicine, unpleasant side effects and personal sensitivity for some pets are likely. However, tests show that Heartguard Plus is safe and well-tolerated when used correctly, leading to a very low incidence of digestive and neurological side effects.

Heartguard Plus uses ivermectin which causes paralysis and death of parasitic worms. The dose of ivermectin contained in the Heartgard is relatively low with a low risk of side effects. As mentioned, you mustn’t start a spoilage program before your pet checks for the presence of heartworm.

Check the required dose for your pet as severe side effects often result in a larger dose to be administered than recommended. If the dose given is correct and you notice any of the side effects listed below, take your pet to the vet immediately.

  • Digestive problems: The most common side effects associated with Heartguard Plus are digestive problems such as nausea, vomiting, and diarrhea. In clinical field trials, vomiting or diarrhea within 24 hours of dosing was seen in only 1.1% of cases.
  • Hypersalivation
  • Depression and lethargy. Depression, lethargy, loss of appetite, and lack of interest in activities have been observed in some pets.
  • Lack of coordination (ataxia), disorientation and hind leg paralysis
  • Stumbling may run into walls and furniture or paralysis.
  • Thin pupils (mydriasis) or blindness
  • Cry
  • Low body temperature and hypothermia
  • Seizures and Muscle Tremors: Seizures, tremors, and convulsions are very rare and may mean that your pet has a particular sensitivity, the dose is too high or heartworm was already present.

Susceptible breeds

Some dog breeds have mutations in the multi-drug resistance gene (MDR1), which makes them more sensitive to ivermectin at very high dose levels (16 times higher than recommended levels). In trials, no adverse reactions were observed on dogs ten times the recommended dose of Heartgard.

This gene mutation is known to be most common in breeds such as Collies, Australian Shepherds, Shelties, and long-haired blankets. The level of ivermectin used for the prevention of heartworm is generally safe and at levels appropriate for these dogs. You can talk to your vet about testing your dog for a gene mutation.
