My ds (who's 3) loves my dog (who lives with my parents but we see him lots) and is really good friends with him. He's quite old and has suddenly become quite ill. I think it's not going to be long before he has to be put down. Does anyone have any advice or experience in how to break the news? Should I let ds say goodbye, even come to vets if it happens? My parents are going to be devastated, quite apart from how I feel. I think ds is so young he'll forget easily but he might be more upset by seeing how upset we are... how do you explain death to a 3 year old?
