Parasite Prevention

Protect your pet from fleas, ticks, heartworms, and more with year-round parasite prevention plans.

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, but 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 Matters

Parasites 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:

  • Itchy, irritated skin

  • Allergic reactions (especially to flea bites)

  • Transmission of Lyme disease, ehrlichiosis, and other tick-borne illnesses

  • Intestinal upset, weight loss, or anemia from worms

  • Potentially fatal heartworm disease

  • Risk of zoonotic transmission (parasites that spread to humans)

With the right plan in place, most of these issues are entirely preventable.

Common Parasites We Guard Against

External Parasites

  • Fleas – cause skin issues and may lead to flea allergy dermatitis

  • Ticks – can transmit serious diseases with just one bite

  • Mites – microscopic pests that lead to ear infections and mange

Internal Parasites

  • Roundworms, hookworms, tapeworms, whipworms – live in the intestines and can cause digestive problems, especially in puppies and kittens

  • Heartworms – transmitted by mosquitoes, heartworms grow inside the heart and lungs and can be life-threatening if untreated

Prevention Options We Offer

We tailor parasite prevention based on your pet’s lifestyle, age, and regional risks. Options include:

  • Monthly chewable or topical preventives

  • Routine deworming (especially for puppies, kittens, or outdoor pets)

  • Annual fecal exams and heartworm testing

Many of today’s preventatives offer broad-spectrum protection—one dose can cover multiple parasites.

What to Watch For

  • Scratching or biting at the skin

  • Scooting or licking around the rear

  • Visible worms in stool or vomit

  • Lethargy, coughing, or changes in appetite (potential signs of heartworm)

If you notice any of these symptoms, it’s best to schedule an exam right away.

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.

Answers to Common Questions

Harbor View Veterinary Hospital keeps track of your pet's weight just like your doctor's office keeps track of your height and weight each time you visit. Having an accurate and current measurement of your pet's weight will help us ensure that we prescribe the right dose of preventives, medications, and any needed anesthetics. It can also help us notice any early clues to health concerns. In addition, a regular weigh-in can help you track and manage your pet's weight.

Call us. Just like doctors, veterinarians sometimes need to try more than one treatment/medication to find the correct solution to cure or manage a pet's condition. Please let us know if something we recommended or prescribed isn't helping. We want to work with you to find the right answers for your pet.

Veterinarians can't diagnose over the phone. Besides being unethical and illegal, diagnosing by phone doesn't allow veterinarians to physically examine a pet. A physical exam is necessary so your veterinarian can provide an accurate diagnosis and proper treatment. Treating a pet for the wrong disease or condition will cost more in the end and could be harmful or even deadly to your pet.

Spaying and neutering can have major benefits for your pet, including lowering or preventing the risk of several diseases and types of cancer. Your veterinarian will be happy to discuss these benefits. In addition, spaying and neutering helps control the pet population by reducing the number of unwanted pets. Spaying and neutering are surgical procedures that require your pet to be put under anesthesia. The cost of these procedures takes into account the anesthesia, your veterinary team's time and expertise, monitoring, drapes, suture material, and hospitalization. Spaying or neutering your pet is much less expensive than feeding and caring for litters of unwanted puppies or kittens or dealing with potential pregnancy complications.

Your veterinarian will determine which vaccinations are appropriate for your dog or cat, based on individual factors, such as lifestyle and health status. Veterinarians commonly recommend that dogs be vaccinated against rabies, distemper, Lyme, and Leptospirosis parvovirus and that cats be vaccinated against rabies and panleukopenia (feline distemper). Additional vaccines, such as feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and Bordetella (kennel cough), Lyme, and Leptospirosis are recommended based on your cat or dog's risk. Many of these diseases can be fatal to your pet. Preventing them is far easier and less expensive than treatment. If you would like more information on vaccines, ask your veterinarian.

For the safety and protection of all clients, patients, and veterinary team members, we require all pets to be on a leash or in a carrier when they arrive at our hospital. They must continue to be restrained while they are in the reception area and while traveling to and from the exam rooms. Your veterinarian or veterinary technician will let you know when it's OK to let your pet off leash or out of his or her carrier. There is often a lot going on at our hospital. Combine that with unfamiliar surroundings and new animals, and any pet-even one that is well trained-might become uneasy or overly excited. We want you and your pet to have as pleasant an experience as possible every time you visit our hospital, so we ask all our clients to respect our policy.
