Parasite Prevention

Fleas, Ticks, Heartworms, and More: What You Need to Know

Pets are beloved members of our families, and keeping them free from parasites is crucial to their overall health. Both external parasites (ectoparasites) like fleas and ticks, and internal parasites (endoparasites) like worms, can affect your pet at any age.

External Parasites

Fleas and ticks aren’t just a nuisance—they can spread diseases like Lyme disease, Rocky Mountain Spotted Fever, and even Bartonella (cat scratch disease). Fleas can also cause flea allergy dermatitis, resulting in itchy, inflamed skin for your pet.

Internal Parasites

Roundworms are the most common internal parasite in pets, but hookworms, whipworms, and tapeworms are also prevalent. Pets typically get infected through accidental ingestion of parasite eggs from contaminated areas or from eating infected rodents or fleas. These parasites can also be transmitted to humans, causing conditions like organ damage or blindness if ingested.

Heartworm Disease

Heartworm is a serious internal parasite transmitted by mosquitoes. While not zoonotic, it can lead to heart failure and death if left untreated. Early stages might show no symptoms, but as the disease progresses, pets can develop coughing, exercise intolerance, or vomiting. Treating heartworm can be risky and expensive, which is why prevention is key.

Preventing Parasite Infestations

Since parasites can pose a risk to both your pet and your family, year-round parasite prevention is essential. Effective preventatives can protect your pet from heartworm, intestinal worms, and tick-borne diseases. In addition, practicing good hygiene—like washing hands frequently, avoiding unwashed raw veggies or undercooked meats, and cleaning up pet waste—can further reduce the risk of zoonotic diseases.
