Parasite Prevention

Fleas, ticks, and heartworm are a constant threat to your pet’s health that must be taken very seriously. Not just irritating, these parasites can cause serious health issues, with heartworm being fatal if not properly treated. The team at Greenwood Animal Hospital works with you and your pet to prevent these diseases from harming your pet.

    • Fleas are small, jumping insects that live off of the blood of animals. They can carry dangerous diseases and will often cause allergic dermatitis” severe itching” in pets.
    • Infestations of fleas can be difficult to get rid of, and, since flea eggs can survive a very long time, it‘s hard to get rid of them completely. It is much better to prevent fleas than to have to try to eliminate them.
    • Greenwood Animal Hospital carries safe, effective flea control products that can be tailored to your needs.


    • Ticks are external parasites that live off of the bodily fluids of animals. They can carry diseases from one animal to another and are the primary cause of the spread of diseases such as Lyme diseaseEhrlichiosis, and Rocky Mountain spotted fever.
    • Dogs and cats that contract a tick-borne disease experience painful symptoms that can leave permanent damage. Prevention is the best course of action.
    • We recommend that both dogs and cats remain on monthly tick preventive. Our knowledgeable staff can help you select the preventive that is best suited for your pet.


    • Heartworm is a parasite that can live in the heart of dogs and cats. Mosquitoes carry the worm from one infected animal to another. Several hundred worms can live in the heart of a dog and infection from the parasite causes significant damage and can be fatal.
    • We recommend that dogs be tested for heartworm once a year and that both dogs remain on heartworm preventive medication. Our experienced staff can help you select the preventive medication that is best suited to your pet.

We’ll be there to make sure these diseases keep their distance from your pet’s life. If you think your pet may be suffering from one of these parasites, please contact us immediately.
