tommy - I'm so sorry as I know how hard it is. One thing to remember is that you gave him a good loving life and home and that's something that a lot of animals never know. Cherish the good memories and believe me when I say that he will always be with you. It takes a lot of courage to know when it's the right time and even more love to recognize it. For every pet we loose, there is another one out there that needs your love and the security of a good home - you'll know when it's time. Until then, know that others who have had the same experience have you in their thoughts and prayers.
