My heart slowly dies crumbling

My heart slowly dies
crumbling as it goes
little by little it breaks
and falls away down below.
My best friend may be dying
her four paws tread so weak
each moment without her
I feel incomplete.
She's lived ten long
years, which is grand
Not enough for a woman,
or a man
but long long years
for my four footed friend
I hate you are ill
I ache to make you well
but even the best medicine
only goes so far.
You will always be my best friend
on four feet or two.
An angel in fur, with silly
mad grace. Prancing in snow
or tugging a rope,
you have always been an odd
dog with such a silly face
but I write this vainly in hope
that this is not soon to be the end
for my heart cannot crumble much more
not again.
If God were listening to my prayers day and night
you'd live another twenty years and even that
would not be enough for us to be right.
Such a spirit in you burns so blindingly bright
still I need that spark of light you brought
to me, when all was darkest and I was broke.
I do not wish to bid you adieu others tell
me its a matter of time, far to few years
have we had, and far too many tears have I shed
but it will never be enough to repay one
bit the love you my friend brought to me.
I only hope you know I love you too.
My dear friend and my dog.
