Me too, my dog is 11 atm and well shes showing signs of age. I fear the day that she dies cause that dog has saved my life, and I have saved her life (quite litterally) I had to give up dogs before as well and thats almost as bad as them dieing. I feel for you and wish you the best of luck.
Aww man...thats even worse, it's like taking your brother to kvorkian.
You going to get another one? Or maybe you guys aren't ready for another pet yet? Sometimes it can be hard to get over and you just don't want another pet.
