They had not gone very far before Sue cried:
"Oh, Bunny! Look! There's that yellow dog—the one that had the tin can tied to his tail—the one that upset our lemonade stand!"
"So it is!" said Bunny.
And, just at that moment, Splash also saw the yellow dog.
With a bark and a wag of his tail, Splash gave a big jump, nearly throwing Bunny and Sue out of the wagon. Then the big dog began to run after the little one.
"Whoa! Whoa!" cried Bunny, pulling on the reins. But Splash would not stop. Faster and faster he ran. He only wanted to see his little yellow dog friend again, and rub noses with him. But I guess the yellow dog was frightened when he saw the express wagon, with the two children in it, following after Splash.
Maybe the yellow dog thought the wagon was tied to the tail of Splash, as the tin can had once been to his own. And maybe the little yellow dog thought some one would now tie an express wagon to his tail. At any rate he ran on faster and faster, And Splash, who just wanted to speak to him, in dog language, ran on faster too.
"Bumpity-bump-bump!" went the wagon with Bunny and Sue in it.
"Whoa! Whoa!" called Bunny.
But Splash would not stop. He was running away, but he did not mean to. He just wanted to catch up to the little yellow dog who was running on ahead.
