Worm infestation is common for horses. There are numerous parasites that can infect your horse, ranging from roundworm to tapeworm, redworm to pinworm, depending on its species, age, pasture, and climate. Have you ever wondered why your horse has such a rough haircoat even after grooming? Or have you noticed that the foals are not growing properly? Do they suffer from diarrhea, constipation, or respiratory issues? This could all be coming from a single issue. Raising a horse is a lot of work and adding multiple vet visits can quickly become pricey.

The symptoms of a parasite infection vary depending on the type and number of worms infecting the horse. Many parasite infections go undiagnosed while the parasite burden is low, but many worms can induce symptoms and have negative effects on the horse’s health.

There are a few things more stressful than noticing the symptoms of worms in your horse. A horse dewormer is used to inhibit the development of internal parasites. It is almost impossible to eradicate the internal parasites, so the purpose of using a dewormer is to keep your horse’s parasitic load at a manageable level.

Choosing the Best: What to Look For

Active Ingredients

Horses have different parasite burdens, and even horses in the same herd can have different worm infestations. As a result, before determining which dewormers to use, it’s important to identify each horse’s worm burden and distinguish the active ingredients in available dewormers. For instance, Fenbendazole-based products exclusively treat roundworms, bloodworms, and pinworms, whereas products containing Ivermectin and praziquantel treat all parasites.

Safety

Another element to consider is the dewormer’s safety. Is it effective on all horses, regardless of their age or physical condition? Are there any downsides? These are some of the questions to consider before deciding on the best dewormer. Some products are not recommended for pregnant mares or foals who are underweight, while others are regarded as safe for all.

Verified Review: User Experience

A user expresses her excitement about the Bimeda Equimax Horse Dewormer: “Maybe it’s odd to have a favorite wormer, but this is mine. The tubes are easy to use, easy to hold, and the actual wormer is kind of… sticky? Gloopy? I’m not sure how to describe it, but if you get it back into their mouth, they have a hard time spitting it out instead of swallowing it. By their reactions, I don’t think it tastes as bad as most either. I’ve been using Equimax for years on multiple horses, and (knock on wood) no one has ever had a bad reaction/tummy ache/etc. And with all these pros, it also gets the job done. Favorite!”

The Quest Gel Wormer Moxidectin is a favorite for spring. One user shares his experience: “Quest is my go-to spring dewormer for most horses. Moxidectin is extremely effective and has lower anthelmintic resistance than most equine dewormers. After getting fecals done, Quest does a great job, and I haven’t had any adverse effects.”
