All right so my dog has been crying and shaking really bad tonight, he is about ten years old and never acted like this, he even growled at my mom at one point when she tried getting close to him, but he hasn't done that since. He cried the most when trying to drink some water. What could possibly be wrong?

He needs to go to the vet. There are too many things it could be including swallowing something that is stuck in his throat. From your description, he is in major pain and discomfort.

Consult your vet.
