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.

Grass Lake Animal Hospital FAQs

There is no question too big or too small for our veterinary team.

No, there is no advantage to letting your pet have one litter. However, Grass Lake Animal Hospital advises that there are plenty of advantages to having your pet spayed or neutered. These advantages include decreasing the chances of breast tumors later in life, decreasing the chance of cystic ovaries and uterine infections later in life, decreasing the desire to roam the neighborhood, decreasing the incidence of prostate cancer later in life, helping prevent spraying and marking, and also decreases the surplus of unwanted puppies and kittens. Please discuss any questions you might have about whether to spay or neuter your pet and when to do it with one of our technicians or doctors.

Most procedures involving external skin sutures require them to be removed in 10-14 days following the surgery. Most spays and neuters do not have external skin sutures and do not need to return here at Grass Lake Animal Hospital for suture removal.

This is a blood test that is run here in the clinic of Grass Lake Animal Hospital prior to surgery. It tests the organ functions, blood counts and clotting function of your pet. The pre-anesthetic blood screening is done to assure safety during surgery and the ability to heal following surgery.

Here at Grass Lake Animal Hospital, spaying or neutering can be done at approximately 6 months of age. Your pet is given an exam prior to surgery to help determine whether your pet is healthy enough to undergo the surgical procedure. Current vaccinations, negative fecal and up-to-date heartworm tests if appropriate are required at the time of surgery. A pre-anesthetic blood screen is recommended prior to undergoing anesthesia and surgery. You can find more information in our FAQ about anesthesia.

Payment is required at the time of service. Grass Lake Animal Hospital offers CareCredit as an option for those who need a way to make payments.
