    "Jeffers Ivermec paste"

    I have been using this as my main wormer for my cows, horses and dogs. Even a goat that would stop in now and again. Took some to a friend and wormed their sheep, goats, and chickens by squirting wormer on bread pieces. Use high fat horse feed when I worm the cows and horses with it. Squirt on my finger to worm the dog monthly, as it is the wormer and the heart worm medicine all in one. Nary have I had a dog with a cough and the die in their mid teens, so I must keep it here at all times. TYou

    Great product! Works fabulously and you can't beat the price! Shipping is quick and ordering is easy! Highly recommended! We've been using this wormer for years and we run anywhere between 18-30 headed horses. Thanks Jeffers!

    Works just as well as more expensive brands. Please check stool samples Before using any deworming products. Two of my seven didn't need anything! Rotate products!

    I use this brand in lieu of the pricier brands that contain the exact same ingredients. The results are just as good as the big name brands.
