Has anyone come across Gorse allergy in dogs?

My 9mth old Lab comes up in pustules on the top insides of his hind legs if he comes into contact with it.

I have searched books and the net but can't fiind any information on treatment or cure.

very common in horses, especially ones that hunt on Dartmoor...moor fever we call it..there is a simple cure....don't go near gorse!

Thanks, I've seen it in horses too.

Haven't yet found a way to make a gundog understand that he can only retrieve from areas free from specific plants!!
