My horse suddenly stopped sweating in May this year. We tried a few different supplements that other people had on hand. Nothing helped, we couldn’t really ride due to his internal body heat riding too rapidly. An acquaintance from anther barn suggested MetaSweat. I ordered it immediately! My horse has no problem eating it am/pm and the sweating started after one week. It’s been 5 months and he now sweats appropriately for the weather and work. We were able to show this month because he finally became fit enough. MetaSweat really saved my horse. Until your horse doesn’t sweat snd is breathing way too hard you don’t realize the seriousness of anhidrosis…. Thank you Perfect Products!!
