Hee hee

I had a similar experience when in boots asking for benzyl benzoate, its a human scabies treatment which i didnt know until I asked for it!
Ive recentky bought a new boy and he had 'areas of hardened skin' quote vets report, which we assumed was last years sweet itch. He was also totally bald, clipped out with no mane at all and a tail which was in a sorry state of disrepair. So, we knew we would be in for a challenging summer and you may read tales of despair later in the year but for now..he is covered head to toe in a bug rug, it has 3 straps around the belly which I keep pretty tight,it has a really long tail flap and goes up over his ears. I would love a snuggy hood one but they are twice the price of a bug rug so got to save up! Ive already had reports of him skidding along the field on his belly so obviously he is itching already. I go thim some 'Killitch' today which , when I got home, I realised is benzyl benzoate again- wish i got it from a chemist now!
Anyway, hope you sort your pony out, its a horrible thing being itchy and seems increasingly common. Fingers crossed for a midge-less summer!
