Bless you, for thinking about your boy, before yourself. Most of us tend to keep a dog alive cause we can't bear how to live with out them, in the mean time, they suffer for us without complaining. I miss my boy more than I think I can bear, but when his liver failed and he was suffering, I had him put down in hours, not days. He was the best thing that ever happened to me. I hope we can both be twice blessed, and be able to have another of God's brilliant creatures to brighten our lives, Thank you, Linda Kearns
