On Wednesday Dougal woke up at 4:30am literally screaming. I have never heard anything like it. He had a back operation 5 years ago and has had problems which have been medically managed ever since - but nothing like this. I tried to comfort him, and for the first time in nearly 11 years he bit me really hard. Took him to the vet - because he was being aggressive, the vet tried to put a muzzle on him but neither him or I could do it, he was so distressed. Vet tried to sedate him with oral sedatives but he still wasn't able to treat him. He told me I could take him home sedated without any treatment or PTS. He was clearly in such pain and distressed I decided on the latter. I am completely broken now and all I can think about was that I should have tried to get him home and get another opinion. Best friend anyone can ever have. RIP Dougal. I am in bits.
