I got some bad news that my 5 yr old male shows signs of kidney failure from what i described to my vet this am. He was 105# in December and today is 80#, He has 2 sunken head spots, black stool and little to no appetite. (NOT GOOD) He will have the blood results tomorrow and know for sure. He even mentioned maybe 90 days. I need insight on making the best of a bad situation. I am shocked and torn up about this. What can i do??? What are my options???
