Sweet Itch? what's sweet about an itch?!?

This morning I was talking with Henry about why he has not been out with us in the fields or in the Horse Watching sessions, and he explained to me that he gets very bad Sweet Itch. 

We asked Teddy about it and he said Sweet Itch is also know as Summer Seasonal Recurrent Dermatitis, which sounds a bit of a mouthful to me! 

In the hot weather there are lots of nasty little flies about, which none of us like, but for poor Henry they are particularly annoying; he is is allergic to their saliva, so the bites make him very itchy and he rubs himself.

At this time of year we all get fly repellent put on to make us more comfortable, and we get washed off quite often when we have been working which feels great and cools us down. 

Because Henry has such a bad reaction to the flies, he gets to wear some special clothing; he has a fly mask for his face and a fly proof rug for when he is out in the fields.
