Parasite Prevention Products

Consistent parasite prevention is one of the most important components of your pet’s year-round health care. We carry a range of veterinarian-recommended flea, tick, and heartworm prevention products for dogs and cats, including:

Heartgard Plus

A monthly chewable that protects dogs against heartworm disease and treats and controls roundworms and hookworms.

Sentinel

A monthly flavored tablet for dogs that prevents heartworm disease and controls flea populations by interrupting the flea life cycle, while also protecting against roundworms, hookworms, and whipworms.

Nexgard

A monthly beef-flavored chewable for dogs that kills fleas and ticks, including ticks that may carry Lyme disease.

Nexgard Combo for Cats

A topical solution for cats that provides protection against fleas, ticks, roundworms, hookworms, and tapeworms in a single monthly application.

Simparica Trio

A monthly chewable for dogs that combines heartworm prevention with flea and tick control, as well as protection against roundworms and hookworms.

Seresto Collars

A long-lasting flea and tick collar available for both dogs and cats, providing up to eight months of continuous protection.

Our team can help you determine which preventative is the best fit for your pet based on their species, lifestyle, and health history. If you have questions about switching products or starting a new prevention protocol, we encourage you to discuss it with our team at your pet’s next visit.

Why Purchasing Through Your Veterinarian Matters

It can be tempting to search for lower prices on pet medications and health products through third-party online retailers, but purchasing veterinary products outside of an authorized source carries real risks. Products sold through unauthorized channels may be counterfeit, improperly stored, expired, or otherwise compromised in ways that aren’t immediately visible.

When you purchase products through Porter Square Veterinarian or our authorized online store, you have the assurance that every product has been sourced, stored, and handled appropriately. Manufacturer guarantees and rebate programs also typically apply only to products purchased through authorized veterinary channels, meaning you may have additional recourse if a problem arises.

Prescription Diets

For pets managing specific health conditions, the right diet can be just as important as the right medication. Porter Square Veterinarian carries a selection of veterinary prescription diets formulated to support pets with a range of medical needs, including kidney disease, urinary conditions, gastrointestinal disorders, weight management, food sensitivities, and diabetes.

We currently stock prescription diets from the following trusted brands:

Royal Canin Veterinary Diet

A range of condition-specific diets formulated for dogs and cats, covering renal support, gastrointestinal health, urinary care, weight management, and more.

Hill’s Prescription Diet

A well-established line of therapeutic pet foods developed with veterinary input to support pets managing chronic and complex health conditions.

Purina Pro Plan Veterinary Diets

A select range of Purina veterinary-grade diets available in limited supply for pets with specific dietary needs.

Because we maintain a limited in-clinic supply of prescription diets, we ask that existing clients call ahead to confirm availability before making a trip to the clinic. Prescription diets require a valid veterinary prescription and are available only to patients currently under our care.

If you have questions about whether a prescription diet is appropriate for your pet, our team is happy to discuss your pet’s nutritional needs during a visit. Learn more about our approach to pet nutrition on our pet nutritional counseling page.
