Here's a couple I use for my dog sympathy cards:
"God promised at the birth of time,
A special friend to give,
His time on earth is short, he said,
So love him while he lives.
It may be six or seven years
Or twelve or then sixteen.
But will you, till I call him back,
Take care of him for me?
A wagging tail and cold wet nose
And silken velvet ears,
A heart as big as all outdoors,
To love you through the years.
His puppy ways will gladden you
And antics bring a smile,
As guardian or friend, he will
Be loyal all the while.
He'll bring his charms to grace your life
And though his stay be brief,
When he's gone the memories
Are solace for your grief.
I cannot promise he will stay
Since all from earth return,
But lessons only a dog can teach
I want you each to learn.
Follow his lead and gain a life
Brim full of simple pleasure,
Whatever love you give to him,
Returns in triple measure.
Enjoy each day as it comes,
Allow your heart to guide,
Be loyal and steadfast in love
As the dog-child at your side.
Now will you give him all your love,
Nor think the labor vain,
Nor hate me when I come to call
To take him back again.
I fancy each of us would say,
"Dear Lord, thy will be done,
For all the joy this dog shall bring,
The risk of grief we'll run.
"We'll shelter him with tenderness,
We'll love him while we may,
And for the happiness we've known,
Forever grateful stay.
"But shall the angels call for him
Much sooner than we've planned,
We'll brave the bitter grief that comes,
And try to understand."
-----------------------------
"May I go now?
Do you think the time is right?
May I say goodbye to pain filled days
and endless lonely nights?
I've lived my life and done my best,
an example tried to be.
So can I take that step beyond
and set my spirit free?
I didn't want to go at first,
I fought with all my might.
But something seems to draw me now
to a warm and loving light.
I want to go. I really do.
It's difficult to stay.
But I will try as best I can
to live just one more day.
To give you time to care for me
and share your love and fears.
I know you're sad and afraid,
because I see your tears.
I'll not be far, I promise that,
and hope you'll always know
that my spirit will be close to you
wherever you may go.
Thank you so for loving me.
You know I love you, too.
That's why it's hard to say goodbye
and end this life with you.
So hold me now just one more time
and let me hear you say,
because you care so much for me,
you'll let me go today."
Dedicated to everyone who has ever had to put down a beloved dog.
I do have another one but will have to look it out and type it up.
