Hooray, hooray! Merlin got a clean bill of health at the vets today!!! Tummy all good, and ears totally cleared up as well!!! She agreed that he probably had the bacteria in his gut for weeks if not months, no wonder he sometimes was a bit funny about his food... He has lost quite a bit of weight and weighed 35.6 kilos today, down from over 38 kgs a couple of months ago. He looks good though - I think we will try to keep him at between 36 and 37 kilos, as it is best for his hips for him to be on the slim side.
He was such a good boy; although clearly worried by being at the vets again he still jumped up onto the table when asked, and although he was shaking and trembling he let the vet palpate his stomach and stick the camera thing down his ears. I was really proud of him.
Now he is snoozing next to me on the couch. My good Merlin-Man, lots of fuss and attention and love for you today!
