My morganXhaflinger gets sweet itch starting around this time every year. I’ve ruled out NTWs after multiple attempts with the ivermectin protocol. The climate here is a temperate rainforest - ideal for the blasted noseeums to prosper.
He is usually in a Boett or knockoff from just before dusk to just after dawn, naked during the day when the bugs aren’t out and the sun makes it unbearably hot for him in his sheet. Unfortunately they never seem to fit him right. They always end up rubbing the crap out of his shoulders/chest and I always need to alter the neck to fit his gelded-way-too-late neck and stop choking him. He is super compact but THICK. I also end up having to replace the buckles on the leg straps and belly band all the freaking time because the plastic buckles like to break. A LOT. And replacing them makes the straps never adjust quite the same again afterwards which is also super frustrating. The fabric also rips super easily if he catches it on a rough spot on the wood of his stall or if his neighbors play a little too rough. I end up having to replace the bloody thing every season and it is getting really old.
Are there other sheets out there that could work for a sweet itch horse that would be more durable and maybe less restrictive in the shoulders? Maybe something like the Rambo hoody or Amigo aussie barrier? Bucas apparently makes a version of their zebra sheets specifically for sweet itch, but the last fly sheet i tried from them was weird and the belly band had zero adjustability and was so big I probably could have wrapped it all the way around him instead of clipping it to the appropriate rings, but it was so narrow in the chest that I couldn’t remotely close it. So I’m not too optimistic about Bucas.
