I don't think there is anything wrong with letting them know that you helped her in her suffering by having her put down. It's a good way to explain that death happens and being merciful to end her suffering is a good thing.

That's the problem with dogs. You know they are going to die. My 'ol girl is 11 and she's getting up there. Starting to have a lot of problems, as old hound dogs will do. She's comfortable, but I'm not going to take extraordinary measures on her at her age. If she gets bad, I'll put her down.

...and then drink a lot. She's a damn good dog...
