    "Works really well"

    I've been using this particular calming powder for quite some time on Rescue Horse & Dogs, in particular those that have been abused or mistreated. I also use it on burned out Show Horses who are sick of being in a stall during show season. It works very well, yet it does not make animals drowsy, helps them focus if in training, & even calms down Stallions during breeding season. I feed a double dose 2 hrs before breeding a stallion. If you need a calming powder this one works, as I have tried many different ones.

    "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!
