Guess it must have been a bee or wasp as when I woke and went down to see him this morning he was as bright as a button and back to being his nosey self.
Should have been called Parker not Scoobz.
However, if it happens again it will be straight to the vets.
Also got myself some of that bee sting treatment as I have heard the second or subsequent times, as suggested above, can be worse than the first.
Thanks for all the advice.
