Several years ago, HorseTech started selling several canine products as part of our PupSup Products line. PupSup canine products are made right here in Laurens, Iowa--just like the HorseTech equine supplements that you've used for over a decade.

These beneficial strains support normal digestive function, maintaining proper gut flora and pH!
