So sorry for your loss, he was a beautiful boy. I think the following is appropriate at this time of loss:
Some Horses
Some Horses come into our and quickly go
Others stay awhile,
Make hoof prints on our hearts,
And we are never, ever the same
Author Unknown
and to bring some comfort here is another of my favourites
Somewhere
Somewhere in times own space
There must be some sweet, pastured place
Where creeks sing on and tall trees grow
Some paradise where horses go
For by the love that guides my pen
I know great horses live again
Author Unknown
Hugs to all of you
