came home from a mates place today and these little lumps are on my STB horse richie over his left side shoulder and two or three on his back. Are they misquito bites? my mum is usually the one that looks after richie when im out, she didnt see them this morning?? hmm.. p.s. the lump on his whither is permanent from his racing career (u cant really see it from the sunlight), the vets said to leave it.
