Making a poem for a stone for family dog

I've been working on a mosiac gravestone for a family pet. He was a goldern retriver and his name was Fetcher since he would fetch things.

Fetcher, old dog
You’ve been loyal and true
And we all are sad
Saying goodbye to you.
Does Heaven have dogs?
I hope that its so
I guess I’ll find out
When someday I go.
If Heaven has dogs
I know it is true
God saved a great spot
For a good dog like you.

We love you Fetcher!
