I had to euthanize my dog of 11 years last month, I still think about him every day.
I'm sorry to hear that, I have two dogs and know how they become part of the family.
Thanks for realizing my pain. It saddens me that I these lovely companions can't live with us forever. 
I know, it's defenitly painful to have to go through but its part of life. Maybe get a new puppy to start loving/sharing life with, shelters have so many dogs that need homes!
