I know how you feel.We went through the same thing with Ruffles.First ,he went blind,then deaf,was then tripping over himself and couldn't stand for long periods without falling so it was Dad's decision as hard as it was to have him put down.It was sad seeing him go downhill that last year.He had been so healthy up to then.I guess if he doesn't get better sometime soon,I feel you may have to make a hard choice,but it may be the best way.At least he would be out of pain.
