Into the cart jumped Splash and he barked:

"Bow-wow!"

It was just as if he said:

"Whoa, now!"

I don't know whether or not Toby understood dog talk. But he did understand the next thing that happened. For Splash reached over and took hold of the reins in his teeth, pulling back on the lines.

Toby had been taught to stop whenever he felt a pull on the reins, whether any one said "whoa!" or not. And this time, feeling himself being pulled back, and not knowing it was only Splash who was doing it, Toby stopped.

"Bow-wow!" barked Splash again, sort of down in his throat, for he was still keeping his place in the cart, and holding to the reins. "Bow-wow!"

It was as if he said:

"See what I did now!"

Bunny and Sue, hurrying down the street after their pony that had walked away, saw what their dog had done.
