This song should perhaps remain private, because only
animal-lovers can truly understand the depth of grief
that can be felt at the loss of a canine friend. That
said, other composers have written tributes to their
pets (including the late, great John Barry), and you
may care to study the unique compound time-signature
(6+4) and chromatic cadences in this song. Certainly,
there is more than basic 3-chord harmony here !
