I have been there too with my yorkie tucker, he had a liver shunt, there was no amount of money that was going to stop me to make him better, after having him 4 years, but then after surgery and they said nothing else could be done, I couldn't take looking in his eyes when he would have a really bad episode...I honestly think that was one of the hardest decisions I have had to make in my life....Great story, I knew there were more people out there that loved there animals like me...God bless them....
