One of my male Goldies has been itchy for ages, even to the extent that the fur on his belly turned bright pink from the saliva and his constant licking and nibbling. He had also been to the vets who reckoned it was a flea allergy (although I was not convinced as he is de-flead on a regular basis), so just to follow vets advice I sprayed the house and the dog. No improvement, as I suspected.
Recently I have tried something called STOP ITCH from Wendals (www.wendals.com) and although I didn't hold out much hope it seems to be working. It is made up of natural herbs (cleavers, dandelion, fenugreek seed, garlic, golden rod, nettles, sage and seaweed).
Hope this helps - good luck!
