Canine hookworms resistant to treatments

            Hookworms are a common problem in dogs. These worms have a hooklike mouth that attaches to the dog’s intestinal tract. There are serious consequences if a dog in highly infested. Currently the most prevalent breed to have hookworms are Greyhounds. The conditions that they are raised and raced in is conductive to the spread of hookworms.

            Because of the widespread adoption of racing greyhounds’ hookworms are spreading to other dogs as well. A dog does not have to ingest the worms to become infected. The larvae live in the soil and can burrow through the dog’s skin and paws. Also, a female can pass the worm to their puppies through their milk. Hookworms also can infect people.

            What is upsetting is that veterinarian researchers have found high levels of hookworms in dogs that were treated. It is important that dogs are retested after a treatment to ensure that all of the worms have been killed.

            The most upsetting thing about hookworms is that they are becoming resistant to the three medications used to deworm a dog. The researchers are concerned that only the drug resistant hookworms will be left and will spread. Right now, the only deworming medication that is successful in killing the resistant hookworms is emodepside. However, that medication is only approved for cats.

            What a dog owner can do is avoid dog parks, where hookworms can live. Have your dog tested for worms frequently, especially if it is an adopted Greyhound, and make sure if your dog has hookworms, retest after treatment.
