I am so sorry for the pain that you are going through right now but try to remember all the love that you have shared with your little Max and the joy that you have brought to each other and know that he will always be with you no matter where you are.
And yes there is a

and that is where he will be running and playing and doing all of his favorite things and he will be there watching over you until you are once again reunited with him.
Hugs and prayers to you
Mary
