Sorry for your loss! We had to put our 16 year old dachshund to sleep last week. She was gradually getting worse day by day and could see she was in pain, so we had to make a tough choice. But even though it was the right thing to do, losing a pet is never easy. This my second dog I had to put down and it's so difficult. I know what your going through and you'll begin to cherish the memories and still shed a tear out of the blue thinking about him/her as well...
