Resistant Hookworms in Dogs

[Dr. Jeff]

Recent research out of Georgia shows that the number of resistant cases of hookworms in dogs, which is one of the common intestinal parasites, is increasing.

These super-hookworms seemed to have developed in racing Greyhounds and now are spreading among other dogs.

Panacur/Safeguard, Strongid (pyrantel pamoate), ivermectin, etc. do not kill this parasite.

If your dog, especially if s/he is a Greyhound, has a stubborn case of hookworms, your vet may want to run a special stool test which uses stool samples two weeks apart.

Here is an excerpt from a 4/30/20 vet article:

The only practical method to diagnose anthelmintic resistance in A caninum is the fecal egg count reduction test, in which the number of worm eggs per gram of feces is measured both prior to and 2 weeks after treatment. Most large animal clinicians are familiar with this test, as testing for anthelmintic resistance on livestock farms has long been recommended. Due to the emergence of MDR hookworms in dogs, small animal clinicians should also become familiar with this test, which should be performed in any dog that has persistent hookworms.

NEW RESEARCH: Multiple-Anthelmintic Resistance in the Canine Hookworm

New research has led to several discoveries of veterinary importance relating to anthelmintic resistance in Ancylostoma caninum, the canine hookworm. Discover these findings and how they may impact veterinary patients and clinicians.

Hookworms resistant to all commonly used drugs are another reason to minimize drug use and to optimize intestinal immune function.

You can do that with a varied fresh food diet and rotation through high quality probiotics and enzymes like:
