That's a relief to hear. Sweet Itch is very frustrating. Could you perhaps share some farm's websites I could look up?Around 10% of imported horses have it, but those born in the US don't have it nearly as often. This is because of what they are exposed to as foals. I have 3 Icelandics. 1 has mild sweet itch (I fly spray her in the summer & leave a fly sheet on), and my other 2 are fine. It also can run in bloodlines.
