Dangerous Parasitic Diseases & Conditions in North Charleston

External parasites like fleas, ticks, and mosquitoes love Charleston’s warm and humid climate. They are able to thrive all year long due to the fact that our area does not go through a hard freeze for a long enough period of time to disrupt the parasites’ life cycles. Internal parasites like heartworms, intestinal worms, and protozoal parasites are also extremely common.

Parasites pose several risks to your pet, especially since many of them are able to transmit dangerous and even deadly diseases. Some of these parasites can also be passed from your pet to you or other members of your family.Pet Parasite Prevention in North Charleston, SC


  • These blood-borne parasites are carried in their larval form by the mosquito. Once your cat or dog is bitten, the larvae are transmitted into their bloodstream, developing into adult worms that live in the heart. This is a fatal disease if left untreated. There is no treatment for heartworm disease in cats.

Lyme disease and Ehrlichiosis

  • These diseases/conditions are transmitted by ticks and can cause a variety of symptoms, including fever, inappetence, limb swelling, and neurological signs.

Flea Allergic Dermatitis

  • Although not life-threatening, this condition is extremely uncomfortable for dogs and cats. A flea-allergic pet will experience severe itching and skin irritation for several weeks from one single flea bite.

Why Prevention is Preferable to Treatment
