I'm so sorry for your loss. It always makes me sad and angry to hear about loose dogs, and to see them in my neighborhood. What an awful way to lose such a sweet young pup. I don't know if it will help you, but I found this sonnet and read it to my first greyhound the day he died:
Mindful of you the sodden earth in spring,
And all the flowers that in the springtime grow,
And dusty roads, and thistles, and the slow
Rising of the round moon, all throats that sing
The summer through, and each departing wing,
And all the nests that the bared branches show,
And all winds that in any weather blow,
And all the storms that the four seasons bring.
You go no more on your exultant feet
Up paths that only mist and morning knew,
Or watch the wind, or listen to the beat
Of a bird's wings too high in air to view,--
But you were something more than young and sweet
And fair,--and the long year remembers you.
And, since Hannah left so long ago, and yet your grief is so raw:
Time does not bring relief; you all have lied
Who told me time would ease me of my pain!
I miss him in the weeping of the rain;
I want him at the shrinking of the tide;
The old snows melt from every mountain-side,
And last year's leaves are smoke in every lane;
But last year's bitter loving must remain
Heaped on my heart, and my old thoughts abide!
There are a hundred places where I fear
To go,--so with his memory they brim!
And entering with relief some quiet place
Where never fell his foot or shone his face
I say, "There is no memory of him here!"
And so stand stricken, so remembering him!
Edna St. Vincent Millay
