Hi. We've decided to let him go
It has been a tough decision, but he has so many things wrong with him and the vet was pretty adamant that he was in pain. The swelling in his leg has not gone down, and that's apparently being caused by his tumour blocking the blood flow. He also has a very sore bum and has had loose stools for about 3 weeks - again probably due to the tumour. Last week was pretty bad - he would just stand staring into space, probably because he couldn't get comfy. It's been tricky because this week he has seemed better. Last week he wouldn't go for walks, but this week he been enjoying a little stroll. But... we've decided the facts are there - he has a tumour in his abdomen that the vet is convinced is causing him a lot of pain, he has a swelled leg which must also be uncomfortable, and he has a very sore bum which is not getting better. Also, the tumour is not going to get any smaller by itself, and he is too old and poorly to think about treating it.
He's just such a little sweetie. Will be so odd without him. The vet is going to come round here to do it. Up to now, I have been adamant that I don't want to be here (my partner will be). But now I'm starting to think maybe I should be here with him when he goes. I don't want to regret not being there for him.
Sorry, long post. Very sad,
