Best Horse Dewormers of 2026

"Living in a wet climate like Washington, I’m always careful about keeping my horse worm-free. My vet suggested this product for part of our annual deworming rotation. It’s worked reliably for us, keeping my horse healthy and clear of worms. The application process is simple, and my horse doesn’t mind it much. I definitely recommend this for anyone wanting to keep their horse’s gut in good shape!"

"As a veterinarian, I use this product for my horse only when fecal egg counts show a significant parasite load. It’s a dependable dewormer for strongyles and tapes. However, I urge people to avoid over-medicating—targeted deworming based on fecal results is best for long-term effectiveness and animal health. The convenience of online ordering is a plus, though it may cost a bit more than in some stores."

"When I needed to treat my cats for giardia, I carefully calculated the dose and used this product since I couldn't afford multiple vet visits.

"My horses and donkeys take this with no fuss at all—so much easier than using oral paste dewormers. I just mix it in and they eat it right up."

"I’ve been using this for years and my mules always finish their dose. It’s far better than gel types, and I love that it's delivered on time and is more affordable than buying locally."

"Honestly, I didn’t see any results and felt like the product was not as advertised. Customer service was unhelpful when I asked for a refund, which was disappointing. I ended up keeping the product but wouldn’t recommend it based on my experience."
