First time last year the big dog got stung i could see him running through the wood then fall down, get up and fall down, get up and fall down. He wasn't whining or nothing but eventually got to me and he was covered in wasps. I knocked them off but there was loads about so i decided to get out of there pronto incase the other dogs got stung. Got along the road a bit and he fell over again....there was one wee b*****d right up in side his front leg, stinging away.....
