very sorry for your loss.
i've had to put two of my dogs down, and even though it was done out of love and because we didn't want our friends to suffer, it was very hard. especially with our border collie who only lived three years due a birth defect. that was sad. but my family always remembers what a great friend she was for the short time she was around.
you'll always remember the good times!
