The Importance of Parasite Control in Dogs

Parasites are a constant danger to your dog that can range from an annoyance to life-threatening. In this post, our Edgewater vets will go over some of the most common parasites and why it is so important to prevent the infection and practice parasite control for dogs.

What is a parasite?

A parasite is an organism that feeds on your dog without offering any benefit. They steal nutrients from them, and some can cause irreversible damage to your dog's organs.

Why should I worry if my dog doesn’t interact with other animals?

Insect bites, another animal's feces, and even being passed down from mother to child before they are born are all ways for your dog to become infected. And once a dog is infected, it can be difficult to get some parasites out. As a result, the best solution is to take preventative measures. Some parasites that dogs may have include:


Mosquitoes are a common vector of heartworms. Once infected, the worm grows, reproduces, and spreads throughout the dog's body. Because of the worm's habit of embedding in the heart muscle, they were given the name heartworm. Not only can they be found in the heart, but in the lungs and blood vessels of an infected dog too.

The problem with diagnosing them is that by the time the symptoms appear, the infection has progressed quite far. Internal organs can be severely damaged by these worms. It is unlikely that humans will become infected with this parasite from their dog.


This parasite can be transmitted from mother to child before birth. It can also be transmitted through eggs that are excreted and then swallowed. The egg can survive for weeks without a host and can infect humans, particularly children. In dogs, this can cause stunted growth and a pot-belly appearance. Roundworms also emerge from both ends.


The dreadful hookworm can infect your dog by them consuming the infected mother's milk, eating the hookworm eggs, or having the hookworm burrow into the skin. These creatures are tiny vampires that feed on the blood of dogs by entering the GI tract and tearing holes in the lining, causing ulcers. They are lethal to young puppies and can cause anemia in adult dogs. These parasites can burrow into human skin as well. Sandboxes are notorious for being vectors of transmission (why do we let kids play in sandboxes?).


The classic pest that infests your dog’s fur. They are normally an annoyance, constantly biting and causing skin irritation. They can be a disease vector for the different kinds of worms.


These little bugs bury their heads into the flesh of their victim. They can spread Lyme disease and can attack humans

How are parasites prevented in dogs?

Parasites are prevented in dogs by keeping up with their vaccinations. Your vet will be able to advise you of a schedule for inoculation. Make sure your dog goes for an annual wellness check so your vet can test for infestation.


Parasites are terrifying and can be fatal to your dog. Continue to use preventative measures to protect them. And please have your dog's and children avoid sandboxes.
