Deworming & Parasite Control: Keeping Your Pet Healthy from the Inside Out
Parasites aren’t always visible, but they can cause serious health issues if left untreated. Deworming and parasite control are key components of your pet’s wellness care—helping protect them from discomfort, illness, and even diseases that can spread to humans.

Whether your pet is an adventurous pup or a stay-at-home cat, regular parasite protection is essential to their health.

Why Deworming and Parasite Control Matter

Intestinal worms, fleas, ticks, and heartworms can impact pets at any age. Some pets show clear signs, like scooting or vomiting, while others have no symptoms at all. Without proper prevention, parasites can lead to:

  • Digestive issues (vomiting, diarrhea, weight loss)

  • Anemia or malnutrition

  • Itchy skin or allergic reactions

  • Life-threatening conditions like heartworm disease

  • Transmission of parasites, such as roundworms and hookworms, to humans

That’s why prevention and routine screening are just as important as treatment.

Common Internal and External Parasites

Internal Parasites (Worms):

  • Roundworms

  • Hookworms

  • Whipworms

  • Tapeworms

  • Giardia

  • Coccidia

External Parasites:

  • Fleas

  • Ticks

  • Mites

  • Lice

How We Protect Your Pet

Our parasite prevention plans are tailored to your pet’s age, lifestyle, and risk factors. We offer:

  • Oral or topical monthly preventatives

  • Flea and tick treatments

  • Deworming protocols for puppies, kittens, and adult pets

  • Annual fecal exams to detect internal parasites

  • Annual heartworm testing and prevention

  • Treatment for diagnosed infections or infestations

If your pet is active outdoors, visits dog parks, travels, or lives in a multi-pet home, more frequent parasite prevention may be recommended.

What to Watch For

  • Visible worms in stools or around the rear

  • Diarrhea or vomiting

  • Weight loss despite normal eating

  • Excessive itching or biting at the skin

  • Scooting or dragging the bottom

  • Coughing (possible sign of heartworms)

If you notice any of these signs, it’s best to schedule a visit so we can test and treat promptly.


Protecting your pet from parasites is easier than treating the effects of an infestation. Regular prevention helps keep your pet comfortable, healthy, and protected year-round.
