I told the vet this and he said maybe a fleajumped on, bit him andjumped off and the dog had an allergic reaction. I almost laughed but didnt.
yeah that's kinda what he suggested..but surely where there is one flea there would be more..and if it had free access to a dog why would it jump on then jump off again..just doesn't seem to make sense to me!
They shaved the area and I have some cream to put on it to try and stop the itching. Have to go pick up some flea tablets on Tuesday, there goes another $100!

Thanks Anila, it could be mozzies, there have so so many of them around lately. Would they be able to get to his skin through all his fur though?
