I have been at my Mother's bed side three time in the last year. Each time thinking it would be the last. I can sympathise and understand your lose.

One of my best friends (I count very few as best friends) put a gun to his head several years ago. I could think of many reasons not to go to the funeral. The one reason I did go was the wife and family he left behind.

Dogs, well they are part of the family. Loosing one is never easy.

The "gathering" may not be for you. It will mean something to those immediately involved.

Your choice.
