Product Reviews by Customers

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Best Wormer Ever!! This is the best wormer I have found to date. I have one horse who hates wormer and another who had a bad battle with worms. After using this product my nightmares in both cases are done. Both eat this wormer with no problem and it cured my other horses worms in a matter of days. I will be buying this for my worming needs.

Need good wormer

My horse doesn't like paste wormers.
Jeannie G on Jan 31, 2014
My horses love this wormer. And it is much easier to use than the paste type wormers. Great for rotation.

what is the usual daily dose.....want to order the smallest amt. ..How long will it last?
doris z on Jan 1, 2015
Best Answer: This is a one-time dewormer designed to replace that day's grain ration. If you would like a daily feed-through dewormer, please go to the red "Wormers" tab near the top of our web page and click on "Daily Feed Through" to see all of that type of dewormer.

is this for swine also?
A shopper on Oct 18, 2015
Best Answer: I'm sorry, I have no idea. Best think would be to call a vet specializing in large animals, such as horses, cows, etc.
