Hookworm

Hookworms are small, thread-like parasites of the small intestine where they attach and suck large amounts of blood. These parasites are found in almost all parts of the world, being common in dogs, and occasionally seen in cats.

Symptoms are usually diarrhea and weight loss. The parasites can actually suck so much blood that they cause pale gums from anemia, and black and tarry stools. Young puppies can be so severely affected that they die. Infection can be by ingestion of breast milk from an infected mother, by ingestion of infected eggs, or by skin penetration of infected larvae.

Since the adult parasites are so small, they are rarely seen in the stool. Diagnosis of these parasites is by the veterinarian or laboratory finding the microscopic eggs in the stool.

There are a variety of medications that can kill hookworms. The important point to know is that there is no one medicine that will kill all the types of intestinal parasites that exist. Some of the monthly "heartworm preventatives" will also work to treat hookworms.

People exposed to hookworms can develop a rash called cutaneous larval migrans. Infected larvae, usually from contaminated yards, can penetrate human skin and cause red tracts.

Read What Our Clients Say

  • "We've followed Dr.Trefz from his former hospital in Clearwater because we were unable to find a vet that could live up to the high standards Dr.Trefz and his staff provided to our 4-legged family members. The compassion and love shown to us when we lost our best friends to their Heavenly home was such a blessing. Dr. Trefz and his staff are exceptional professionals, friends and great human beings. The 30 minute drive from Clearwater is well worth it for the wonderful care our sweet boy Hunter receives. Love Dr. Trefz and staff!"

  • "Dr. Trefz is the best Vet Doc we have ever had for our dear Katie. He is so caring and really takes an interest in you and your "baby." Dr. Trefz will actually call to check-up on your animal. The entire staff is truly amazing."

  • "We drive over an hour one way to bring our 11 year old Bengal, Sumo, to Dr Trevz. He was Sumos original vet, but when he left the Clearwater practice we "lost him" for a bit. We took a very sick Sumo to Dr Trevz& his staff. We were ready to be told to put him down. But one by one, Dr T tackles his infections and issues...and we almost have him back to perfect health' we are grateful beyond words for the caring and expertise of Dr T & his staff!"
