DON'T just get your dog euthanized. For real. Don't. Tell your parents not to. Tell them to talk to a vet and ask when it's time. A vet will be honest with you and tell you, because they're not in their job to kill old dogs. I'm sure that's the last thing they want to do, but it's something they have to do.
If your dog's pain keeps him in bed all day and he can't get up to relieve himself, then it's time. But otherwise, don't use your own judgment to decide when your dog should die. He might still have a good year in him. A vet's going to be the expert on this, not you, and not your parents. And they should know that.
