Slipped

I fear your leash has no dog following;
You've spent so many hours leading it,
Loving its moods, enduring hallooing,
Teaching it to roll and beg and sit
What will you do now it's no longer there?
I cannot tell you why it left your side,
Or how it slid from off the leash you bear
In vain. I do not know if it espied
Another dog and sought it on its own,
Or if it simply yearned to be more free;
It might have died and left you all alone,
Or be as lost as you, confusedly.
But if you'd like to hear advice, why then
Search for another dog to lead again.
