Sonnet 69, by NY Shakespeare Exchange

Those parts of thee that the world's eye doth view
Want nothing that the thought of hearts can mend;
All tongues, the voice of souls, give thee that due,
Uttering bare truth, even so as foes commend.
Thy outward thus with outward praise is crown'd;
But those same tongues, that give thee so thine own,
In other accents do this praise confound
By seeing farther than the eye hath shown.
They look into the beauty of thy mind,
And that in guess they measure by thy deeds;
Then, churls, their thoughts, although their eyes were kind,
To thy fair flower add the rank smell of weeds:
     But why thy odour matcheth not thy show,
     The soil is this, that thou dost common grow.

Sonnet 69, from The Sonnet Project, by the New York Shakespeare Exchange.

It's a cute move to make the subject of the sonnet a dog.  But this reminds of Prince Hal, in Henry IV (Part 1 and Part 2), who belies, and defies, his royal upbringing by frequenting the neighboring taverns with Falstaff & Co.  I imagine King Henry, the Prince's father, chiding his son for his behavior and company.  I imagine the King referring to Falstaff, in particular, who knows who Prince Hal actually is, but who leads his royal friend into "the rank smell of weeds" and the common soil of villagers.  If I recall correctly, Falstaff bitterly complains of Prince Hal, now King Henry V after the death of Henry IV, treating him like a dog.
