  1. 4.0 out of 5 stars

    "It works on my stallions"

    With breeding season on us I am often times alone when live cover breeding my stallions to mares. With no help, it can be dangerous work, but this product does a fair job. I add Chastetree Berry Powder for the mares as well. Downside is the price.

    "Loving this product!"

    My husband inherited his grandfathers "pasture ornaments." The horses were rarely worked with. Although they were approachable, they would go crazy when trying to halter, curry or mess with their feet. We could tell a big difference after using this product for a few days and were finally able to trim their feet. Getting ready to re-order!
