What Is Pet Parasite Control?

Parasite control covers preventive care against fleas, ticks, heartworm, and intestinal parasites. Because our region rarely sees a hard freeze, these parasites can stay active nearly year-round. Left untreated, parasites can lead to skin irritation, blood loss, or more serious illness in some pets.

We build a prevention plan around your pet’s lifestyle, whether they stay mostly indoors or explore outdoors often. Outdoor cats, hunting dogs, and pets who visit dog parks often need a more robust approach.

What to Expect During Your Visit

A parasite control visit includes a discussion of risk factors and a prevention recommendation for fleas, ticks, and heartworm. We may also recommend a fecal exam through pet laboratory testing to check for intestinal parasites. We often review parasite prevention as part of routine Pet Wellness Exams, though a dedicated visit works too. Our team stays current on the most effective and safe prevention options available.

Why Parasite Prevention Matters

Fleas and ticks can transmit diseases that affect both pets and people, making prevention an important part of care. Heartworm disease is spread by mosquitoes and can cause serious illness in dogs and cats. Routine prevention is generally easier and more affordable than treating an infestation or related illness. Skipping parasite prevention can put your pet at unnecessary risk in a climate like ours.
