“Ironically, resistance is the direct result of the ready availability and ease of administration of dewormers.”
Harold C. McKenzie III, DVM, MS, Dipl. ACVIM. – Veterinary Practice News

“We now are finding entire classes of dewormers are no longer working against the serious equine parasite threat of small strongyles. One of the significant contributors to that increasing failure is that the majority of horse owners are still rotating dewormers, because it’s what they’ve always done. But it doesn’t work. And indications are strong that these practices may contribute to resistance.”
Frank Hurtig, DVM, MBA, director, Merial Large Animal Veterinary Services

“Most veterinarians continue to recommend anthelmintic treatment programs for horses that are based on knowledge and concepts that are 30-40 years old.”

Horse Care: What you don’t know about Worms will surprise you (2016 Care of Horses Edition is a clear easy-to-understand guide to horse worms and dewormers. Although written in easy language for the layperson, the book is heavily referenced to scientific academic journals. Today, the problem horse worm is the small strongyle yet the vast majority of advice given today for worming horses is still aimed at the old methods of eradicating the large strongyle. Rotation is no longer advocated by equine parasitologists. The book cuts through the claims about worming products, both chemical and natural / herbal, and presents the scientific evidence. When to deworm, resistance, rotational deworming, harrowing, are all covered in this book.
Researcher and equine author Dr. A. Nyland has stripped bare the hype, myths, and advertising claims surrounding horse worms and dewormers, both chemical, and natural / herbal. Dr. Nyland believes we need to be informed about the latest research on worming products so we can make informed decisions about the care of our horses, when to worm, and what products to use. Please note this is all fact and not opinion.

Nyland runs the registered horse rescue charity, Morrigan Horse Rescue and Rehab Inc., in Australia.
