It sure sounds like he is dying. It's just so hard to know for sure but it doesn't sound good for him. Did you try and give him the charcoal? It can be put into water but if he isn't drinking that isn't going to help. Giving him a capsule and making sure it goes down the right way might be tricky too. Have you ever given a pill?It could be dissolved in water and fed by a syringe you just have to be very careful it doesn't go down the wrong hole in the back of his throat.
