Stages of Kidney Failure

[Karlson08]

Hi,
My 11 year old maltese was diagnosed with chronic renal failure in November '14.  She is on Pepcid and blood pressure meds.  A few days ago she was also diagnosed with Demodex and is on oral medicine to cure it.  I am going into the vet's office on Friday for new blood work / check up.  I am have read about other dogs' symptoms and I am wondering if there is any sort of progression with the symptoms.  Last visit my vet didn't give me an amount of time that he thought she would survive.  Izzie goes back and forth between drinking tons of water and not wanting to drink at all.  Recently she has been tremoring off and on throughout the day but does not appear to be bothered by these episodes.  She doesn't eat much dog food but will eat almost any human food I give her.  
My question is, even with without excessive vomiting, diarrhea, weight loss, etc. does the increase in tremoring mean she is close to death?
