Importance of Parasite Control in Dogs

Parasites pose a continuous threat to your dog, ranging from annoyance to life-threatening danger. In this post, our Murfreesboro veterinarians will discuss various parasites and emphasize the crucial importance of preventing infections and implementing parasite control measures for dogs.

What is a Parasite

A parasite is an organism that leeches nutrients from your dog, offering no benefits in return. Some parasites can inflict irreversible damage to your dog's organs.

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

Insect bites, contact with other animal feces, and transmission from mother to unborn pups are all potential sources of infection for your dog. Once a dog contracts an infection, removing certain parasites from its system can prove challenging. Therefore, the most effective approach is to take preventive measures proactively. Common parasites that dogs may harbor include:

Heartworm Disease

Mosquitoes commonly transmit this parasite. When it infects a host, the worm actively grows, reproduces, and swiftly spreads throughout the dog's body. This is why it's referred to as heartworm, as it often embeds itself in the heart muscle but can also be present in the dog's lungs and blood vessels. Diagnosing heartworms poses a challenge since symptoms typically manifest only after the infection has advanced significantly. These worms can cause severe damage to the dog's internal organs. Fortunately, the risk of humans contracting this parasite is minimal.


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 infect humans, particularly children (which makes you question every sandbox you played in as a child). In dogs, this can cause stunted growth and a pot-belly appearance. Worms also emerge from both ends.


These dreadful creatures can infect your dog through three primary methods: consuming the infected mother's milk, eating the eggs, or burrowing into the skin. They are essentially tiny vampires, entering the GI tract and tearing holes in the lining to feed on the blood of animals, leading to ulcers. They pose a lethal threat to young puppies and can induce anemia in adult dogs. Additionally, these heinous creatures can also burrow into human skin. Sandboxes, like roundworms, are notorious for serving as vectors of transmission—raising the question of why we allow kids to play in them.


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 tapeworms.


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

How to Prevent Parasites in Dogs

To prevent parasites in dogs, maintain their vaccination schedule and consult your vet for guidance. Ensure your dog receives an annual wellness check to test for infestations.


Parasites are terrifying and can be fatal to your dog. Please continue to use preventative measures to protect your dog. Dogs and children are disease vectors in outdoor sandboxes.
