Man, that sux majorly and I truly feel for you. Had to go through that just a week and a half ago myself when we put down our buddy Cowboy, who was 15. It always hurts. Don't try to hold it in. Mourn him or her well and cherish the memories. I keep ol' Bo's tag on my key ring (he's my avatar <<<<< ), and seeing it and feeling it brings back the good times we had.

The hurt is a testament to your love. And Love endures, and flourishes in spite of adversity, so maybe when the time is right, there'll be enough love for another one. There's a lot of good, wonderful dogs in shelters and with rescue groups that are looking and waiting for good folks to share their love with.

Bring enough gun and know how to use it.

Know that it is not the knowing, nor the talking, nor the reading man, but the doing man, that at last will be found the happiest man. - Thomas Brooks (1608-1680)
