Diagnosis And Treatment

A test called 'fecal float' is recommended by your vet to look for hookworm eggs - if they suspect hookworm infestation in your pet.

Prevention is better than cure, so consult your vet about deworming protocols to avoid getting infected or contaminating the surroundings to prevent hookworm infection as well.

Hookworms in dogs can be treated with a dewormer, or anthelmintic as prescribed by your vet. These are to be taken orally, and will have to be repeated for two to four weeks as recommended by your vet to complete get rid hookworms over the course of a period. The drug kills only adult hookworms and hence is required to be repeated to completely get rid of all hookworms. 

It's rare, but blood transfusion is also required if sever anaemic conditions are developed in your dog.

Since the re-infection is caused by exposure to eggs which are passed on with stool, it's very important to immediately clean and get rid of the stool, to avoid contaminating the environment. One such places are dog kennels where such hygiene protocols are not in place. 

Also speak to your vet to provide hookworm medicines with the schedule for heartworms, and help get rid of both heartworms and hookworms using the same drug.

Last but not the least hookworms can also infect humans, and can cause itch. The infection can happen via the exposure to the moist contaminated soil. The adult hookworms can't infect humans, but if there is exposure to larvae, it can penetrate your skin causing the itch, which is also know as "ground itch" and if the larvae penetrates further into the body like eyes causing blindness and damage to internal organs. Following simple hygiene like regular bathing and washing of hands prevents such infections.
