We're waiting for the vet to call back. When we mentioned to our vet what the vet had said in the hospital last time, he also thought it sounded a bit drastic, but if we have to get him flushed through every 2 months and still keep him on the diet food, it's unbearable. If he has the operation, he won't ever have the problem again - and he may even be able to get his favourite treats again. Ohh, it's so hard to decide! Wish I knew more about it! I have been looking for websites about this and know that it can get quite serious very quickly if not treated, but the actual operation I don't know much about.

Will report back later!
