WOW, Well I think the pink on the back of his head will clear up, possible form a scab and end up being OK, I'm wonder if that bubble of fluids is really attached to him, I'm wondering if it's just gooy stuff stuck to a piece of his skin which would be the "cord". Let me show this to my vet and see what he says.. is he still making noise?.. I'll show this to a couple of other people that might have some advice on this as well... Hang tight will figure out the best thing for him..
