Guide to Choosing Great Horse Wormers for the Fall

Worming your horse is an incredibly simple, yet delicate process. It is relatively easy to execute, and incredibly hard to correct once mistakes have been made. Having the best tools, or in this case, products at hand could help prevent the majority of the potential complications that typically arise. But with all things delicate, trial and error, and the help of a professional are the only way to truly prevent devastating losses.

Choosing the Right Chemicals for the Fall Worming

Worming your horses with a “One product fits all” mentality is one of the biggest mistakes you can make when buying wormers. You have to consider the parasites lifecycle, risk of the disease, age of the horse, the resistance of the worms before you buy products for your fall deworming. For the fall, veterinarians typically recommend products with active ingredients like praziquantel, ivermectin, and moxidectin. A combination on any of these actives are fine, but before you buy them, always consult your vet and see if he/she approves of them.

Foals Are a Different Ball Game Entirely

Foals might technically be horses, and in some cases will need the same doses as mature horses, but their developmental requirements starkly vary from the typical thousand-pound horse. It tend to get infected more frequently, and certain parasites prefer them to older horses. They are in more danger than you might know, and that is why you need to treat them and separate them from other horses. Foals typically need fenbendazole, oxibendazole, ivermectin, praziquantel and moxidectin several times a year. Before treating them with any of the active ingredients above, you should see your vet and come up with a solid plan to tackle unforeseen developments.

In this post, we covered some of the best horse wormer for fall worming and talked about how efficient they tend to be. We, however, skipped out on certain tips and general advice that should make your seasonal deworming easier. The first thing you should know about worming your horse, in general, is to always make sure you always confirm after every session that you got them all. If parasites survive each worming session, it kind of defeats its purpose altogether. We recommend getting worming testers. We also recommend taking special attention to the drugs you purchase when treating foals. It’s irresponsible to use a single type of product to treat all types of horses.
