Parasite Prevention: Protecting Your Pet Inside and Out Parasites may be small, but the problems they cause can be serious. Fleas, ticks, heartworms, and intestinal parasites not only make your pet uncomfortable, they can also lead to major health issues if left untreated. That’s why parasite prevention is a cornerstone of responsible pet care.At our clinic, we take a proactive approach to help keep your pet safe, healthy, and itch-free year-round.Why Parasite Prevention MattersParasites are more than a nuisance. Some carry diseases that affect your pet’s organs, immune system, and even your family. Others, like intestinal worms, may go unnoticed until your pet shows signs of illness.Preventive care helps avoid:<ul><li>Itchy, irritated skin</li><li>Allergic reactions (especially to flea bites)</li><li>Transmission of Lyme disease, ehrlichiosis, and other tick-borne illnesses</li><li>Intestinal upset, weight loss, or anemia from worms</li><li>Potentially fatal heartworm disease</li><li>Risk of zoonotic transmission (parasites that spread to humans)</li></ul>With the right plan in place, most of these issues are entirely preventable.Common Parasites We Guard AgainstExternal Parasites<ul><li>Fleas – cause skin issues and may lead to flea allergy dermatitis</li><li>Ticks – can transmit serious diseases with just one bite</li><li>Mites – microscopic pests that lead to ear infections and mange</li></ul>Internal Parasites<ul><li>Roundworms, Hookworms, Tapeworms, Whipworms – live in the intestines and can cause digestive problems, especially in puppies and kittens</li><li>Heartworms – transmitted by mosquitoes, heartworms grow inside the heart and lungs and can be life-threatening if untreated</li></ul>Prevention Options We OfferWe tailor parasite prevention based on your pet’s lifestyle, age, and regional risks. Options include:<ul><li>Monthly chewable or topical preventives</li><li>Injectable preventatives (for heartworm)</li><li>Routine deworming (especially for puppies, kittens, or outdoor pets)</li><li>Annual fecal exams and heartworm testing</li></ul>Many of today’s preventatives offer broad-spectrum protection—one dose can cover multiple parasites.What to Watch For<ul><li>Scratching or biting at the skin</li><li>Scooting or licking around the rear</li><li>Visible worms in stool or vomit</li><li>Lethargy, coughing, or changes in appetite (potential signs of heartworm)</li></ul>If you notice any of these symptoms, it’s best to schedule an exam right away.<div data-type="horizontalRule"><hr></div>Parasite prevention is simple, affordable, and highly effective. Staying consistent with your pet’s prevention plan protects not only their health—but also your household.💙 Whether it’s a checkup, questions, or care needs, visit us—we’re here to be your partner in your pet’s health.
