I am so sorry about Sasha passing away. I have had several pets and it was extremely sad when each of them passed away. People here have given some great advice about helping Sammy with Sasha's death.
I just wanted to say that there is a book I like called "Dog Heaven" that has a lot of very colorful, nice and happy pictures of dogs "in heaven". They look happy and are having a lot of fun. Even if your son doesn't know what heaven is, or even if your beliefs don't include heaven, this book might be helpful because it shows a lot of dogs playing together and having a happy and peaceful time together. It's really a lovely book. (There's one for cats, too, called "Cat Heaven").
I'm sorry you have to deal with this. I'm sure it is very hard. Best wishes to you and your family.
