Parasite Prevention

Protecting Your Pet From the Inside Out

Parasites can pose serious health risks to pets—and some can even affect people. At O’Connor Animal Hospital, we offer comprehensive parasite prevention care to help keep the pets of Irving healthy, comfortable, and protected year-round.

Flea & Tick Prevention

Fleas and ticks are more than just a nuisance—they can transmit disease and cause skin irritation, anemia, and allergic reactions. We recommend veterinarian-approved flea and tick preventatives tailored to your pet’s lifestyle, size, and risk level.

Heartworm Testing, Treatment & Prevention

Heartworm disease is a serious and potentially fatal condition transmitted by mosquitoes. Our team provides:

• Routine heartworm testing
• Thorough treatment plans when needed
• Safe, effective monthly preventatives to protect your pet year-round
• Consistent prevention is the best defense against heartworm disease.

Intestinal Parasite Screening

Routine fecal exams allow us to detect intestinal parasites such as roundworms, hookworms, whipworms, and giardia. Early detection helps prevent health issues and reduces the risk of transmission to other pets and family members.

Customized Prevention Plans

Every pet is different. We work with you to create a personalized parasite prevention plan based on your pet’s age, health status, lifestyle, and exposure risk—ensuring they receive the right protection at the right time.

Protecting Pets & People

Many parasites can be transmitted from pets to humans. Preventive care not only safeguards your pet’s health but also helps protect your entire household.

Year-Round Protection You Can Trust

With Irving’s climate, parasite risks don’t stop with the seasons. Our veterinarians recommend year-round prevention to provide continuous protection and avoid gaps in coverage.
