My dear sweet Bella, I am so very sorry. I usually find the words to comfort strangers when this happens to them, but it's not easy when it's someone I know and love.
You've told me so much about Max, even though I never got to meet him. I know how much you love him (I won't say loved, because that love is still there, and always will be).
There aren't any words that can take away the pain. I could tell you that Max had a great life, and he was a very lucky dog to have found you. I could tell you that 12 years of wonderful is better then a lifetime of nothing special. I could tell you all of that, and it's all true, but it won't take away the pain you're feeling now.
I'm crying with you, sending you all my love, hugs, and comfort. I wish I could be there with you right now to hug you in person.
If it should be that I grow frail and weak
And pain should keep me from my sleep,
Then will you do what must be done,
For this -- the last battle -- can't be won.
You will be sad I understand,
But don't let grief then stay your hand,
For on this day, more than the rest,
Your love and friendship must stand the test.
We have had so many happy years,
You wouldn't want me to suffer so.
When the time comes, please, let me go.
Take me to where to my needs they'll tend,
Only, stay with me till the end
And hold me firm and speak to me
Until my eyes no longer see.
I know in time you will agree
It is a kindness you do to me.
Although my tail its last has waved,
From pain and suffering I have been saved.
Don't grieve that it must be you
Who has to decide this thing to do;
We've been so close -- we two -- these years,
Don't let your heart hold any tears.
