Oh how hard it must be for your Grandma! I'll pray that Charlie has quality of life for a while yet. Your Grandma will know when the time comes.
How ridiculous of the vet to deny meds because it will hurt the liver of a teminal dog! Quality of life is better than quantity of life. Right now Killian is on a drug for autoimmune that is not good for his liver disease. BUT since he is on this drug (necessary for the autoimmune d), the quality of his life has gone way up. He acts so much more normally now. However, it is not good for his liver. In the end, he will most likely die from liver disease and nothing will change that. But for now, he is really enjoying life! So sometimes drugs that give quality of life, do take away quantity of life.

Prayers for Charlie and your Grandma!
