Brownian motion

The brown dog in my neighbourhood, who will hereafter be known as Brown Dog, is a frequent recipient of pats from yours truly. Typically, the correspondence between Brown Dog and myself goes like this:

1) I walk up to his house.

2) I see Brown Dog in the front yard.

3) I call Brown Dog over.

4) Brown Dog proceeds to

Flip flip
Lollop lollop
Wiggle wiggle
Flollop flollop

Over to my side.

There is a stick of wood in the front yard along with Brown Dog, and sometimes this makes a slight difference to the distinctive Brownian motion of Brown Dog. The flop flop bit, etc, still happens the same, but it's what happens afterwards that's unique - Brown Dog will

Flump flump
Flounce flounce

Over to the stick, and

Flollop flollop
Bounce bounce

Back over to the fence. Then he will indulge in a perverse game in which he dangles the stick above the fence and then moves the stick back behind the fence so it is unreachable. This is driven by two competing desires in the Brown Doggian heart: the desire to fetch the stick, and the desire to keep the stick. He can never quite decide which is best, with the result that he can stand there, turning to and from the fence for hours.

This morning, however, I arrived at the fence and called Brown Dog over. This time he didn't

Flollop flollop

Nor did he

Nor did he

over to the fence. Rather, his motion was more akin to a

Flop flop
Bloop bloop.

Indeed, there was something distinctly dejected about it. He was certainly an eager recipient, as always, of pats, but one had to wonder what the cause of this sorrowful flopping and blooping was. Why the absence of the typical lolloping and flumping? How did his flollop get broken? What can I do to bring Brown Dog back to his usual flollopsome self?
