Yes dogs can get heartworms from fleas. Fleas are carriers of heartworm larvae and can spread the disease if your dog contracts it. Fleas are tiny, wingless insects that live on their hosts’ blood. In addition to feeding on the host’s blood, fleas also feed on organic matter such as skin flakes and dead tissue, as well as eggs and larval forms of insects such as mosquitoes and mites. It is not uncommon for pets to be infested with thousands of adult fleas at one time. The truth is that while dogs can’t get heartworms from flea bites, they can get heartworms from the saliva in flea bites. If a dog is bitten by a host animal, that animal gets heartworm larvae and stores it in the muscles for about 6 months. When the fleas bite the dog, they are infected with the larvae too and can spread it to other animals and people through their bites. Heartworms, also known as Dirofilariasis, is a disease that is transmitted to canines via mosquitoes and fleas. Fleas are the main culprit for this, as mosquitoes don’t feed on canines. However, it’s important to note that mosquitoes will bite the dog and the fleas at the same time. This means that the canine could get bitten by a mosquito and become infected by heartworms. If you’re asking how dogs contract heartworms, you really must read on to learn more! Heartworm disease is insects’ favorite way to hitch a ride on dogs and then make their way into the pets’ circulatory system, where they can grow in size and number. While it is true that the various species of fleas do not transfer heartworms directly—much to the chagrin of many a pet-owning household—fleas do cause infected mosquitoes to bite, which in turn contributes to the spread of heartworm. Heartworm disease, caused by parasitic worms, has been reported in every state. Heartworms are transmitted from animal to animal or from animal to human, via mosquito bites. Dogs get heartworms (Dirofilaria immitis) from the bite of a mosquito that has fed on an infected host and contains infectious juvenile worms. Fleas are the intermediate host in North America. The worm develops and reproduces inside the flea, which passes the infection during its “blood meal” on an animal or person.

Can Dogs Get Heartworms From Fleas

It is not that common for a dog to get heartworms from fleas

While it can be tempting to simply assume that fleas and heartworms are somehow related, there is no evidence that fleas play a role in the transmission of heartworm disease. Fleas are external parasites that feed on blood, while heartworms are internal parasites (roundworms) that live in the right side of the heart and pulmonary arteries. Heartworm disease is transmitted through mosquito bites: mosquitoes draw up blood infected with microfilariae, which mature into adult worms over a period of months. If a dog has fleas and is bitten by an infected mosquito, it’s possible for him or her to contract both parasites at once. However, this does not increase his or her risk for developing heartworm disease; mosquitoes have no interest in feeding on previously-fed dogs.

How Common is it for a Dog to Get Heartworms From Fleas

While it is not common, dogs can get heartworms from fleas. However, it is important to understand that heartworm disease and fleas are two separate parasites. Fleas are a common parasite and can picked up anywhere. Heartworm disease is a parasite but is fortunately not as common in the US as flea infestations. Heartworm disease occurs when a dog ingests a mosquito carrying microfilariae (heartworm larvae), which then transforms into the adult form of the parasite inside the dog’s bloodstream.

Fleas Can Cause Serious Issues

Fleas can wreak havoc on a dog and their family’s life. If your pet has fleas, they may be more than just an annoyance that causes itching. These tiny pests can carry diseases such as bartonella, tapeworms, and ehrlichia. Fleas also cause flea allergy syndrome in many dogs which is an allergic reaction to their saliva. They can bite other areas of the body besides the skin which can lead to bald spots or “hot spots” (caused by scratching). Flea bites also lead to secondary skin infections from scratching or biting at the site of the bite.

Heartworms Are More Of A Concern For Dog Owners

You should know that heartworms are actually far more dangerous to dogs than fleas. While it’s true that heartworms are transmitted by mosquitoes, they can be fatal if left untreated. It’s estimated that 2 million dogs in the United States are infected with heartworms every year, and less than half of those dogs get treatment. So while only 1% of flea bites lead to tapeworms, heartworm infections kill around 100,000 dogs each year.

The Risk of a Dog Getting Heartworm From Fleas Is Very Low

Dogs get infected with heartworms when they are bitten by a mosquito that is carrying baby worms, called microfilariae. The mosquito deposits the microfilariae in a dog’s bloodstream through its bite. Once in the bloodstream, the microfilariae mature into adult heartworms over the course of six months.

While there have been no documented cases of dogs getting infected with heartworms from fleas, research has shown that it is possible for dogs to become infected this way if enough fleas carrying the disease were biting them at once. However, it’s highly unlikely that this would happen because a dog would need to be exposed to a lot of different fleas in order for them to ingest enough microfilaremiae to even have a chance of becoming infected with heartworm.

A dog would need to be infested with hundreds or thousands of infected fleas (or other insects) at one time for these parasites to transmit enough larvae into their system and cause an infection. And even then, most mosquitoes carry mosquitoes that can infect him or her directly through bites; they don’t carry them indirectly through other insects like ticks or flies on their skin surface.

Most vets will say that the chances of a dog getting heartworm from fleas is only about 1 in 1,000.

Most vets will say that the chances of a dog getting heartworms from fleas is only about 1 in 1,000. However, this doesn’t mean you should skip taking your pet to the vet for its annual exam. Even if they’re only visited once a year, the vet can still spot potential health problems before they become serious in dogs.

For example, your pup could get heartworm from fleas that were on an infected dog or cat that had been biting it and scratching it for several days. Remember, every little bite and scratch matters!

Remember to give your dog preventative treatments for both heartworm and fleas each month. This will help keep them healthy and happy all year long!
