In the first stanza we address youth. A spry horse to carry along the boot, and the idea that "every dog [has] his day" paired alongside the comments of a young world and queenly lasses provide us with a clear idea that the topic we broach is that of youth. The lines "young blood must have its course, lad, and every dog his day" come across as a call to action, demanding perhaps a busier and more productive youth, one in which much is seen and accomplished because in you "every dog [has] his day". Additionally, we are treated to a slue of natural imagery in the form of green trees, geese, swans, the horse, etc. The allusion to a simple, natural order is a compelling one.
