Ali,
I came into this late. First let me tell you how sorry I am that your little fellow is so ill. And he is very ill. It would be the kindest thing you could do to put him to sleep. He is suffering. No amount of pills is going to make him any better. And it looks like the group here agrees with me.

He has lived a long life and it has been a good life if you have cared for him all of it. But if it were my pet, I'd put him to sleep to stop his suffering.

I know it will be hard. But think about the suffering you will save him. Putting him to sleep is painless. I've held my own cocker spaniel in my arms when they had to do this and she simply went to sleep.

I'm sorry,
Billye
